36c3 - FinFisher ev. broke the law

As the software was reversed by Thorsten Schröder and Ulf Buermeyer, it showed hard evidence that the Turkey espionage software was crafted by the germen company finfisher at a time where the export of such thing was already forbidden by german law.

Together with Reporter Without Borders (ROG), the European Center for Constitutional and Human Rights (ECCHR) and netzpolitik.org, the GFF has filed criminal complaints against the managing directors of FinFisher GmbH, FinFisher Labs GmbH and Elaman GmbH.

There are urgent indications that the Munich company conglomerate sold the spy software FinSpy to the Turkish government without the approval of the German government and thus contributed to the surveillance of opposition figures and journalists in Turkey.

Conrad Electronics: Elasticsearch DB with 14 mio. customer records compromised

A big german electronics company (being a supplier for big german companies) has lost his customer data to foreign intruders.
As per the press statement, it included 14 million customer records (but NO passwords and credit card data) that where accessible over the last months to unauthorized attackers.

As this includes names and email addresses, you should be very warily with mails from conrad.de, as this leak could be used (at least) for phishing attempts.

The original (german) statement from Conrad can be found here.

ZDNet: Simjacker attack exploited in the wild to track users for at least two years

 for Zero Day wrote a cool article about SIMJacker being used for the last two years.

The reader that might not have heard about this vulnerability of millions of cell phones, may be interested in below description taken from a very detailed report coming from AdaptiveMobile Systems:

The main attack observed involves two stages:

1) Attack Stage: An SMS ‘Attack Message’ is sent from an attacker to a victim phone number

The Attack Message executable primarily instructs the SIM Card to request Location Information – the current serving Cell-ID of the handset and the IMEI from the Handset, and send the Location and IMEI from the Handset in a 2nd SMS. These instructions are in the form of a series of SIM Toolkit (STK) instructions, which the SIM Card will run to obtain the relevant information.

2) Exfiltration Stage: An SMS ‘Data Message’ is sent from the Victim Handset to a Recipient Phone Number – i.e. the Exfiltration Address.

This activity is not noticeable by the Victim – there is no indication on the handset

Note: This diagram is for illustration. Often the Attackers send the Data Message to a different Recipient Phone Number than that which originated the actual attack.

My personal conclusion:
Despite the information disclosure and GPS tracking ability an attacker has on the victims device, he can use the S@T browser to download/install (in combination of other vulns) any stuff he likes on the device. But think of the "low hanging fruites" of:

  • Fraud Applications
  • Advanced Location Tracking
  • Assistance in Malware Deployment
  • Denial of Service
  • Information Retrieval
  • Misinformation

By the nature of the technology, everything is done with zero-security.

Exploring the MQTT Protocol with ESP8266

Using an RPi as the MQTT broker. We'll explore two-node communication as well as LWT messages (last will).

Story

In any IoT project we have a number of unique requirements and restrictions. The communication strategy to connect devices and send data between them is critically important.

In this guide we will explore a powerful, simple and lightweight messaging protocol over the wire: MQTT

Main Features

  • Data agnostic: you can use it to send sensor data, images or even OTA (over the air) updates
  • Lightweight and bandwidth efficient: smallest frame is only 2 bytes long
  • Per-queue QoS levels
  • Runs on top of the TCP/IP stack, so you can use it to encrypt the data with TLS/SSL and to have a secure connection between clients
  • Simple to develop: clients exist for all operating systems and programming languages
  • Central broker: different devices can communicate with each other without having to worry about compatibility
  • Session awareness: provides an identity-based approach for subscriptions
  • Flexible subscription topics using single-level and multi-level wildcards

Visualize windows eventlogs with LOGONTRACE


Thx to /LogonTracer

While I was busy doing windows event log anaysis the past days, I came across a very cool tool to visualize the different WinEvents with LogonTracer of the JPCERT.

LogonTracer is a tool to investigate malicious logon by visualizing and analyzing Windows Active Directory event logs. This tool associates a host name (or an IP address) and account name found in logon-related events and displays it as a graph. This way, it is possible to see in which account login attempt occurs and which host is used.
This tool can visualize the following event id related to Windows logon based on 
this research.

  • 4624: Successful logon
  • 4625: Logon failure
  • 4768: Kerberos Authentication (TGT Request)
  • 4769: Kerberos Service Ticket (ST Request)
  • 4776: NTLM Authentication
  • 4672: Assign special privileges

While using a docker image, the installation is very easy, so is the use. - Give it a try.

$ docker run \
   --detach \
   --publish=7474:7474 --publish=7687:7687 --publish=8080:8080 \

Google Home Silently Captures Recordings of Domestic Violence and More

 Author Lindsay O'Donnell is writing an article at Threatpost about the same thing as of Alexa now was made public for Google's "Home".

In a Wednesday report, Dutch news outlet VRT NWS said it obtained more than one thousand recordings from a Dutch subcontractor who was hired as a “language reviewer” to transcribe recorded audio collected by Google Home and Google Assistant, and help Google better understand the accents used in the language. Out of those one thousand recordings, 153 of the conversations should never have been recorded, as the wake-up command “OK Google” was clearly not given, the report said.

“VRT NWS was able to listen to more than a thousand excerpts recorded via Google Assistant,” according to the report. “In these recordings we could clearly hear addresses and other sensitive information. This made it easy for us to find the people involved and confront them with the audio recordings.”Google for its part on Thursday acknowledged that VRT NWS had obtained authentic recordings, but argued that its language experts only review around 0.2 percent of all audio snippets.

“As part of our work to develop speech technology for more languages, we partner with language experts around the world who understand the nuances and accents of a specific language,” according to David Monsees, product manager at Google Search. “These language experts review and transcribe a small set of queries to help us better understand those languages. This is a critical part of the process of building speech technology, and is necessary to creating products like the Google Assistant.”

Google did acknowledge that some audio may be recorded by Google Home or Google Assistant without the wake-up word being said, due to error.

As of my earlier writing, the "Project Alias" by  had already thought of this security issue and developed a excellent device made around a Raspy PI, that plays white noise to Alexa or Home while not having heard the "wakeup word". This way, if someone is eavesdroping, he only hears garbage. Still, be deactivating the "garbage" when ever the self definable "wakeup word" was heard, the white noise is turned off and the original function is been established.

A very cool and pragmatic solution…!!! Credits and respects to Bjoern.

Logitech keyboards and mice vulnerable to extensive cyber attacks

heise Security has a brilliant article about several devices of Logitech being vulnerable of MouseJack (CVE-2019-13055)

So checkout your devices for the orange asterisk. *

The vulnerabilities allow an attacker to eavesdrop on keystrokes from wireless keyboards. Everything an affected user types, from e-mails to passwords, is readily available to the adversary. But it gets worse: An attacker can send any command to the victim's computer if a vulnerable Logitech-device is installed. And that makes it easy to infect the computer with malicious code without the rightful owner taking notice.

These products are affected

The Logitech Unifying receivers are recognizable by their orange star logo.(Bild: c't)

Any Logitech device that uses the so-called Unifying radio technology is affected. Logitech has been shipping the vulnerable Unifying USB receivers with wireless keyboards and mice since 2009. Unifying is used across Logitech's product range, from inexpensive entry level devices to current high-end models. The vulnerable USB receivers are recognized by a small orange star logo.

In addition, wireless gaming products of the Lightspeed series and the Wireless Presenters R500 and Spotlight are also affected. They use related radio technology. The Presenter R400, R700 and R800, however, are not affected by the vulnerabilities described in this article.

Upgrade Confluence NOW

As per Atlassians advisory, you should upgrade your onprem installation of confluence rather today than tomorrow.

As per  Alert Logic:

Exploit code for a new vulnerability in Confluence (CVE-2019-3396) has been rapidly deployed by attackers and successfully used to breach hosts. We have observed attempts by these campaigns to execute Gandcrab ransomware on the victim hosts via PowerShell and usage of standard toolsets to avoid detection. Readers are encouraged to assess and patch their environments for this vulnerability as soon as possible.

Proof of concept code for the vulnerability was made available in the public domain on the April 10 and by the next day we were observing the first weaponized attack attempts using this new vector. This emphasizes yet again the critical nature of patching as a core component of your security protection. Don’t wait until exploit code appears in the public domain, or you are reading this blog, to react. By then it might well be too late.

French gas stations robbed after forgetting to change gas pump PINs


By  for Zero Day | March 27, 2019

French authorities have arrested five men who stole over 120,000 litres (26,400 gallons) of fuel from gas stations around Paris by unlocking gas pumps using a special remote.

The five-man team operated with the help of a special remote they bought online and which could unlock a particular brand of gas pumps installed at Total gas stations.

The hack was possible because some gas station managers didn't change the gas pump's default lock code from the standard 0000. Hackers would use this simple PIN code to reset fuel prices and remove any fill-up limits.

Crooks would operate in small teams of two to three individuals who visited gas stations at night using two vehicles.

A man in a first car would use the remote to unlock the gas station, and then a second car, usually a van, would come along seconds later to fill a giant tanker installed in the back of the vehicle with as much as 2,000 or 3,000 litres in one go.

The group advertised the fuel they stole on social media, providing a time and place where customers could come and refuel their vehicles or pick up orders for gasoline and diesel at smaller prices.

Their scheme was uncovered in April 2018, when police arrested a suspect in Sagy, a Paris suburb. The suspect was in the possession of a remote at the time of his arrest. Five men, part of the same gang, were arrested on Monday, according to Le Parisien, who first reported the scheme last November.

Win back some privacy with a cone of silence for your smart speaker


A cool HACKDAY post by  after my collegue brought up an related posting doing the same with Arduino.  :-)

To quote the greatest philosopher of the 20th century: “The future ain’t what it used to be.” Take personal assistants such as Amazon Echo and Google Home. When first predicted by sci-fi writers, the idea of instant access to the sum total of human knowledge with a few utterances seemed like a no-brainer; who wouldn’t want that? But now that such things are a reality, having something listening to you all the time and potentially reporting everything it hears back to some faceless corporate monolith is unnerving, to say the least.

There’s a fix for that, though, with this cone of silence for your smart speaker. Dubbed “Project Alias” by [BjørnKarmann], the device consists of a Raspberry Pi with a couple of microphones and speakers inside a 3D-printed case. The Pi is programmed to emit white noise from its speakers directly into the microphones of the Echo or Home over which it sits, masking out the sounds in the room while simultaneously listening for a hot-word. It then mutes the white noise, plays a clip of either “Hey Google” or “Alexa” to wake the device up, and then business proceeds as usual. The bonus here is that the hot-word is customizable, so that in addition to winning back a measure of privacy, all the [Alexas] in your life can get their names back too. The video below shows people interacting with devices named [Doris], [Marvin], [Petey], and for some reason, [Milkshake].

We really like this idea, and the fact that no modifications are needed to the smart speaker is pretty slick, as is the fact that with a few simple changes to the code and the print files it can be used with any smart speaker. And some degree of privacy from the AI that we know is always listening through these things is no small comfort either.

Malicious applications in circulation! (GanCrab 5.2)


by  | May 8, 2019 | Security Informationen
Original post in German translatet via google translate and put in italcs

Disguised as a professionally designed application mail with an encrypted attachment, an unidentified virus is spreading. This is reported by the Hornetsecurity Security Lab.

Look for emails with the subject "Apply for your job advertisement" or "Apply for the current job advertisement" and an attachment that is encrypted. To open the document, a password will be included in the cover letter of the e-mail. Through the encrypted .pdf, .doc or zip file, cyber criminals try to circumvent local virus scanners because the contained malicious code is thereby "hidden". However, decoding the attachment unloads the virus and infects the computer system.

In order to raise trust with the recipient of this e-mail, a good quality candidate image is often added and referred to the company's website where the alleged candidate has found the vacancy.

As the security researchers from the Hornetsecurity Security Lab now discovered, the spreading malware is a new Gandcrab campaign. Already in January this year and autumn 2018 security experts observed an increased occurrence of this type of malware. The perfidious thing about the spam wave, however, is the encrypted document that downloads the GandCrab Ransomware. The encryption leverages classic checks from the macro code, since a static analysis of the document is not possible. So the encrypted file could not be recognized by any classic anti-virus program.

As soon as the recipient opens and decrypts the attached document, the user is prompted to click the "Enable editing" and "Activate content" buttons. If you do this, the macro in the Office document starts a hidden terminal and runs PowerShell commands to download and run the GandCrab Ransomware from the Internet.

Subsequently, the GandCrab Ransomware encrypts all data on the infected machine and replaces the desktop background with a claim message.


Summary of the key data of the defective e-mail:

Cover letter is written in good German, with professional-looking details of the "applicant"
-The attachment contains an encrypted document in .pdf, .doc or zip format
-The password for decrypting the attachment is also sent in the same e-mail
-The linguistic idiom varies with the sample mail below

Thrangrycat 0Day: Cisco Secure Boot Hardware Tampering Vulnerability

Details

  • An attacker will need to fulfil all the following conditions to attempt to exploit this vulnerability:

    • Have privileged administrative access to the device.
    • Be able to access the underlying operating system running on the device; this can be achieved either by using a supported, documented mechanism or by exploiting another vulnerability that would provide an attacker with such access.
    • Develop or have access to a platform-specific exploit. An attacker attempting to exploit this vulnerability across multiple affected platforms would need to research each one of those platforms and then develop a platform-specific exploit. Although the research process could be reused across different platforms, an exploit developed for a given hardware platform is unlikely to work on a different hardware platform.

Affected products: See this link

China Chopper Malware affecting SharePoint Servers


Number: AL19-006
Date: 23 April 2019

Assessment

The Cyber Centre is aware of a campaign that is currently compromising several versions of Microsoft SharePoint Server in order to deploy the China Chopper web shell. Trusted researchers have identified compromised systems belonging to the academic, utility, heavy industry, manufacturing and technology sectors. The following versions of Microsoft SharePoint are known to be affected:

  • Microsoft SharePoint Enterprise Server 2016
  • Microsoft SharePoint Foundation 2013 SP1
  • Microsoft SharePoint Server 2010 SP2
  • Microsoft SharePoint Server 2019

It is likely that the current campaign is leveraging CVE-2019-0604 in order to deploy the web shell. Microsoft released security updates addressing this vulnerability in February and March 2019; however, many systems remain outdated.

Suggested action

  • All Microsoft SharePoint Server installations should be patched with the latest security update, dated 12 March 2019, using Microsoft Update, the Microsoft Update Catalog or the Microsoft Download Center.
  • If a SharePoint instance serves strictly as an on-premises solution, ensure that the server has no exposure to the Internet.

CVE-2018-12130 ZombieLoad-Attack

Another side channel attack has been discovered

ZDNet has done a post among many others.

And Intel has done an official post about their impacts.

Under certain conditions, data in microarchitectural structures that the currently-running software does not have permission to access may be speculatively accessed by faulting or assisting load or store operations. This does not result in incorrect program execution because these operations never complete, and their results are never returned to software. However, software may be able to forward this speculative-only data to a side channel disclosure gadget in a way that potentially allows malicious actors to infer the data.

Mitigation

Some current processors and future processors will have microarchitectural data sampling methods mitigated in the hardware. For processors that are affected, the mitigation for microarchitectural data sampling issues includes overwriting store buffers, fill buffers, and load ports before transitioning to possibly less-privileged code.

There are two methods to clear microarchitectural structures affected by MDS: MD_CLEARfunctionality1 and software sequences. On processors that enumerate MD_CLEAR2, developers can use the VERW instruction or L1D_FLUSH command3 to cause the processor to overwrite buffer values that are affected by MDS, as these instructions are preferred to the software sequences.

Panama Citizens Massive Data Breach



SECURITY DISCOVERY POSTED BY: BOB DIACHENKO MAY 13, 2019 is writing a post of:

On May 10th I identified a massive bulk of data sitting in an unprotected and publicly available Elasticsearch cluster (hence visible in any browser).

This database contained 3,427,396 records with detailed information on Panamanian citizens (labeled as ‘patients‘), plus 468,086 records with records labeled as ‘test-patient‘ (although, this data also appeared to be valid and not purely test data).

Each record contained the following info:

  • full name
  • date of birth
  • national ID number (cedula)
  • medical insurance number
  • phone
  • email
  • address
  • other info

With Panama’s total population number at 4,1M, the exposed number of 3,4-4,8M records would correspond to almost 90% of the country’s citizens.

I have immediately sent a notification alert to CERT Panama, and within 48 hours the database has been secured.

According to Shodan historical data, the IP in question has been indexed since April 24th, 2019 and it is unknown whether anyone else has accessed the data.

The danger of having an exposed Elasticsearch or similar NoSql databases is huge. I have previously reported that the lack of authentication allowed the installation of malware or ransomware on the MongoDB servers. The public configuration allows the possibility of cybercriminals to manage the whole system with full administrative privileges. Once the malware is in place criminals could remotely access the server resources and even launch a code execution to steal or completely destroy any saved data the server contains.

Google: A global hub for privacy engineering, in the heart of Europe

Sundar Pichai CEO of Google in Munich:

Last week at I/O, our annual developer conference in California, I shared how we’re working to build a more helpful Google for everyone. Keeping people safe online, and their information private and secure, is a big part of how we do this. We believe that privacy and safety must be equally available to everyone in the world, and we bring that to life with products that empower everyone with clear and meaningful choices around their data.

To build on that commitment, this week, we’re officially opening the Google Safety Engineering Center (GSEC) in Munich, Germany. We’re growing our operations and doubling the number of privacy engineers in Munich to more than 200 by the end of 2019, making Germany a global hub for Google’s cross-product privacy engineering efforts. The team will work hand-in-hand with privacy specialists in Google offices across Europe and globally, and the products built there will be used around the world.

It’s no accident that we’re building our privacy hub in the heart of Europe, and in a country that in many ways reflects how Europeans think about online safety, privacy and security. Many of our privacy products have been built in Munich, including Google Account, a central place where you can control your privacy when you use Google products. Today, more than 20 million people visit Google Account every day to review their settings, using tools like Privacy Checkup, which provides a quick and easy walk-through of your privacy settings.

German Secret Service should also be allowed to search online in domestic Germany



Golem.de (Moritz Tremmel) is reporting about a new law proposal that shall allow the german secret service (BND) to be allowed to monitor and "hack" within Germany.
As the german law had only foreseen the BNDs activity on outside of Germany to protect the country of outside threats, changing this to inside the contrys activitys as well is a major change to my point of view. Especially as Germany had some historical reasons of limiting the secret service activity. - We should all remember what happend during the 2nd world war times and during the german democratic replic by germans spying on germans.
Although I have great trust in the germans legislative to create controls on such new duties of the BND, it still makes me think ...

The Social Democratic Party (SPD) already stated out that she will NOT support such action. - So vote wise

New Max Planck Institute for Cybersecurity and Privacy in Bochum

Translated from the German article:

Another decisive step has been taken in founding the Max Planck Institute for Cybersecurity and Privacy in North Rhine-Westphalia: The Joint Science Conference today (3 May 2019) approved the plans to set up the institute in Bochum.

Minister President Armin Laschet: "The decision in favor of Bochum is another award for the excellent research landscape in North Rhine-Westphalia: with the Horst Görtz Institute, the Universities of Bochum and Dortmund, a large number of innovative companies in the IT industry and a high-quality startup Scene, the region has become a renowned hotspot for IT security. The planned new institute will benefit from this with its research on key issues of the future. Bochum and the Ruhr Metropolis provide the ideal environment to explore the key cybersecurity technologies. We want to further expand and network innovative cutting-edge research 'Made in North Rhine-Westphalia'. "

"The scientific expertise available at the Bochum site creates excellent cooperation opportunities for cutting-edge research at this new Max Planck Institute," said Isabel Pfeiffer-Poensgen, Minister for Culture and Science. "The state government is committed to creating the best possible starting conditions for the new institute. The aim is to establish a center of excellence for basic research and training of young scientists in the field of cyber security and privacy. "

The focus of the new Max Planck Institute (MPI) will be on top-level, state-of-the-art research on cyber security, cryptography, IT system security and on legal, economic and social aspects of security and privacy. It aims to cover the entire spectrum from theory to data-driven to empirical research, and to network closely with external researchers in the fields of computer science, physics, mathematics, social sciences, economics and law.

As early as November 2018, the Senate of the Max Planck Society had called for the founding of a new Max Planck Institute for Cybersecurity and Privacy at the Bochum location. The next step towards founding is the special financing of a new building.

The Max Planck Society decided on the location of the new institute in Bochum in a location finding process encompassing several possible locations. The institute will eventually have six departments and twelve Max Planck research groups and an annual operating budget of around 20 million euros.

souvereign Runet

(www.rbc.ru) of the Russian Federation and the end: what risks does the project on sovereign Runet bear

Rusia will have it's "own" Internet for Russia-internal internet communication. Not to control traffic or content of the rusians, but to ensure their internal communication works even in case of global Internet outages and stay safe of outside threat.


The State Duma submitted a bill aimed at strengthening the sovereignty of the Runet. Why the document can reduce the quality of Internet access in Russia and lead to a restriction of the freedoms of users, understood RBC

The main provisions of the bill

Internet providers will have to “ensure installation” in their networks of technical means for countering threats. These funds (which are not explained in the document) should be provided to them by Roskomnadzor free of charge. In cases of threats to the integrity, stability and security of the functioning of the Internet of general use, the service may exercise centralized network management in a manner determined by the government. As specified by RBC Klishas, ​​the procedure, terms and technical conditions for the installation of technical equipment, as well as the requirements for communication networks when using such technical equipment will be established in a sub-legal act of Roskomnadzor.

Even if there is no threat to the Runet, Roskomnadzor will block resources prohibited in Russia through the installed equipment. Now providers are doing it themselves.

The system of organizing the exchange of traffic on the territory of the country is changing completely - it must pass only through exchange points entered in a special register (the principle of its formation is not specified) and according to certain rules of Roskomnadzor (which is not specified).

Introduces the ability to deny service providers and organizers of information dissemination on the Internet (ORI, these include instant messengers, social networks, e-mail services, etc.) to connect to traffic exchange points. The refusal will follow if the operators do not comply with the requirements of Roskomnadzor or law enforcement officers (which ones - not specified).

Owners of communication lines that connect Russia with other countries; telecom operators; Individuals with an autonomous system number (combines groups of IP addresses so that the service provider can build a route for traffic); owners of traffic exchange points will be required to participate in the exercise. The position of the exercise will be set by the Russian government.

It is proposed to create a national system for obtaining information on domain names and network addresses, a registry that will duplicate the list of domain names and autonomous system numbers delegated to Russian users.

New Exploits for Unsecure SAP Systems

Alert (AA19-122A)
New Exploits for Unsecure SAP Systems
Original release date: May 02, 2019 | Last revised: May 03, 2019

Although SAP systems should never ever been exposed directly to the internet as they host a massive amount of sensible data, there have been now defined a lot of vulnerabilities due to false configurations. Thanks to OPCDE (Dmitry Chastuhin and Mathieu Geli and their gatherings. When ever you are doing a SAP-pentest, you MUST this first.

Summary

The Cybersecurity and Infrastructure Security Agency (CISA) is issuing this activity alert in response to recently disclosed exploits that target unsecure configurations of SAP components. [1]

Risk

Vulnerable SAP applications can be compromised by a remote unauthenticated attacker having only network access to the system (without the need for a valid SAP user ID and password). Attackers can obtain unrestricted access to SAP systems, enabling them to compromise the platform along with all of its information, modify or extract this information or shut the system down. Order-to-Cash, Procure-to-Pay, Inventory Management, Treasury, Tax, HR & Payroll, and any other business process handled by SAP can be controlled, affecting the integrity of business information used to build the financial statements.

A person abusing this vulnerability would be able to perform critical business transactions including but not limited to:

  • Creating fake vendors
  • Creating fake employees
  • Creating/modifying purchase orders
  • Changing bank accounts
  • Paying any vendor or employee
  • Releasing shipments
  • Changing inventory data
  • Generating corrupted management reports
  • Bypassing automatic business controls

A person performing any kind of fraud would be able to delete any traces or records that prove his or her actions and an action of this kind may not be detected.

Technical Details

A presentation at the April 2019 Operation for Community Development and Empowerment (OPCDE) cybersecurity conference describes SAP systems with unsecure configurations exposed to the internet. Typically, SAP systems are not intended to be exposed to the internet as it is an untrusted network. Malicious cyber actors can attack and compromise these unsecure systems with publicly available exploit tools, termed “10KBLAZE.” The presentation details the new exploit tools and reports on systems exposed to the internet.

SAP Gateway ACL

The SAP Gateway allows non-SAP applications to communicate with SAP applications. If SAP Gateway access control lists (ACLs) are not configured properly (e.g., gw/acl_mode = 0), anonymous users can run operating system (OS) commands.[2] According to the OPCDE presentation, about 900 U.S. internet-facing systems were detected in this vulnerable condition.

SAP Router secinfo

The SAP router is a program that helps connect SAP systems with external networks. The default secinfo configuration for a SAP Gateway allows any internal host to run OS commands anonymously. If an attacker can access a misconfigured SAP router, the router can act as an internal host and proxy the attacker’s requests, which may result in remote code execution.

According to the OPCDE presentation, 1,181 SAP routers were exposed to the internet. It is unclear if the exposed systems were confirmed to be vulnerable or were simply running the SAP router service.

SAP Message Server

SAP Message Servers act as brokers between Application Servers (AS). By default, Message Servers listen on a port 39XX and have no authentication. If an attacker can access a Message Server, they can redirect and/or execute legitimate man-in-the-middle (MITM) requests, thereby gaining credentials. Those credentials can be used to execute code or operations on AS servers (assuming the attacker can reach them). According to the OPCDE presentation, there are 693 Message Servers exposed to the internet in the United States. The Message Server ACL must be protected by the customer in all releases.

Signature

CISA worked with security researchers from Onapsis Inc.[3] to develop the following Snort signature that can be used to detect the exploits:

alert tcp $EXTERNAL_NET any -> $HOME_NET any (msg:"10KBLAZE SAP Exploit execute attempt"; flow:established,to_server; content:"|06 cb 03|"; offset:4; depth:3; content:"SAPXPG_START_XPG"; nocase; distance:0; fast_pattern; content:"37D581E3889AF16DA00A000C290099D0001"; nocase; distance:0; content:"extprog"; nocase; distance:0; sid:1; rev:1;)

 

Mitigations

CISA recommends administrators of SAP systems implement the following to mitigate the vulnerabilities included in the OPCDE presentation:

Complete Mandiant Offensive VM, the first full Windows-based penetration testing virtual machine distribution

For penetration testers looking for a stable and supported Linux testing platform, the industry agrees that Kali is the go-to platform. However, if you’d prefer to use Windows as an operating system, you may have noticed that a worthy platform didn’t exist. As security researchers, every one of us has probably spent hours customizing a Windows working environment at least once and we all use the same tools, utilities, and techniques during customer engagements. Therefore, maintaining a custom environment while keeping all our tool sets up-to-date can be a monotonous chore for all. Recognizing that, we have created a Windows distribution focused on supporting penetration testers and red teamers.

Born from our popular FLARE VM that focuses on reverse engineering and malware analysis, the Complete Mandiant Offensive VM (“Commando VM”) comes with automated scripts to help each of you build your own penetration testing environment and ease the process of VM provisioning and deployment. This blog post aims to discuss the features of Commando VM, installation instructions, and an example use case of the platform. Head over to the Github to find Commando VM.

Chinese hackers poke the Bayer, but German giant says it withstood attack


Pharmaceutical brand says no data lost in Winnti outbreak

By Shaun Nichols in San Francisco 4 Apr 2019 at 22:12

German pharmaceuticals giant Bayer says it has been hit by malware, possibly from China, but that none of its intellectual property has been accessed.

On Thursday the aspirin-flingers issued a statement confirming a report from Reuters that the Winnti malware, a spyware tool associated with Chinese hacking groups, had been detected on some of its machines.

The malware was spotted on Bayer PCs in early 2018, with the company silently monitoring its behavior for more than a year before finally pulling the plug on the operation last month and notifying authorities.

Thunderclap flaws impact how Windows, Mac, Linux handle Thunderbolt peripherals


By  for Zero Day | February 26, 2019 -- 23:46 GMT (23:46 GMT) | Topic: Security

Windows, Mac, Linux, and FreeBSD systems are all impacted by a new vulnerability that was disclosed this week at the NDSS 2019 security conference.

The vulnerability --named Thunderclap-- affects the way Thunderbolt-based peripherals are allowed to connect and interact with these operating systems, allowing a malicious device to steal data directly from the operating system's memory, including highly sensitive information.

The research team behind this vulnerability says that "all Apple laptops and desktops produced since 2011 are vulnerable, with the exception of the 12-inch MacBook."

Similarly, "many laptops, and some desktops, designed to run Windows or Linux produced since 2016 are also affected," as long as they support Thunderbolt interfacing.

WHAT IS THUNDERBOLT?

Thunderbolt is the name of a hardware interface designed by Apple and Intel to allow the connection of external peripherals (keyboards, chargers, video projectors, network cards, etc.) to a computer.

These interfaces became wildly popular because they combined different technologies into one single cable, such as the ability to transmit DC power (for charging purposes), serial data (via PCI Express), and video output (via DisplayPort).

The technology was initially available for Apple devices but was later made available for all hardware vendors, becoming ubiquitous nowadays, especially thanks to the standard's latest version, Thunderbolt 3.

But according to the research team, all Thunderbolt versions are affected by Thunderclap. This means Thunderbolt 1 and 2 (the interface versions that use a Mini DisplayPort [MDP] connector) and Thunderbolt 3 (the one that works via USB-C ports).

Windows Commands Abused by Attackers and their mitigation

Shusei Tomonaga from the JPCERT is providing us with some cool statistics of commonly used windows internal commands by attackers and shows a cool way of mitigation.

Hello again, this is Shusei Tomonaga from the Analysis Center.

In Windows OS, various commands (hereafter “Windows commands”) are installed by default. However, what is actually used by general users is just a small part of it. On the other hand, JPCERT/CC has observed that attackers intruding into a network also use Windows commands in order to collect information and/or to spread malware infection within the network. What is worth noting here is the gap between those Window commands used by general users and by attackers. If there is a huge difference, it would be possible to detect or limit the attackers’ behaviour by monitoring/controlling the Windows command execution.

Building a large scale Intrusion Detection System

The Swiss CERN is providing us with an exellent article on how to build a large scale IDS. This is really worth reading (and building) as it does not use expensive commercial LMS.

In this paper the implementation of an Intrusion Detection System (IDS) both at the Network (NIDS) and Host (HIDS) level, used at CERN, is presented. The system is currently processing in real time approximately one TB of data per day, with the final goal of coping with at least 5 TB / day. In order to accomplish this goal at first an infrastructure to collect data from sources such as system logs, web server logs and the NIDS logs has been developed making use of technologies such as Apache Flume and Apache Kafka. Once the data is collected it needs to be processed in search of malicious activity: the data is consumed by Apache Spark jobs which compare in real time this data with known signatures of malicious activities. These are known as Indicators of Compromise (IoC). They are published by many security experts and centralized in a local Malware Information Sharing Platform (MISP) instance. Nonetheless, detecting an intrusion is not enough. There is a need to understand what happened and why. In order to gain knowledge on the context of the detected intrusion the data is also enriched in real time when it is passing through the pipeline. For example, DNS resolution and IP geolocation are applied to it. A system generic enough to process any kind of data in JSON format is enriching the data in order to get additional context of what is happening and finally looking for indicators of compromise to detect possible intrusions, making use of the latest technologies in the Big Data ecosystem.

Here comes the Sun (and TheHive 3.3-RC5)

New version of TheHive has been released.

On February 10, 2019, we released TheHive 3.3-RC2. It contained new features such as bulk alert merging, alert sorting, observable tag autocompletion, exporting case tags to MISP & more. Since then your favourite French code Chefs have been beesy refining TheHive 3.3 through new release candidates while getting Cortex 3 ready for prime time.

Over the weekend, Nabil decided he was not working enough already during the week. So he drained his batteries to the very last drop to release TheHive 3.3-RC5 before he crashed headfirst into his bed for a long, reparative sleep. Cumulatively since RC2, we added several features and squashed 10 bugs as described below.

Note that release candidates are beta software. You can get TheHive 3.3-RC5 from the pre-release, beta repositories. As usual, we encourage you to test it and report any bugs or issues you spot so we can address them before the final release. 

Check TheHive Installation guide for further details.

Technical Analysis: Pacha Group Deploying Undetected Cryptojacking Campaigns on Linux Servers

Introduction

Cryptomining malware, also known as cryptojacking or cryptocurrency mining malware, refers to software developed to take over a computer’s resources and use them for cryptocurrency mining without a user’s explicit permission.

There are several reports documenting this newer malware breed and how it has become more popular in the last few years.

Antd is a miner found in the wild on September 18, 2018. Recently we discovered that the authors from Antd are actively delivering newer campaigns deploying a broad number of components, most of them completely undetected and operating within compromised third party Linux servers. Furthermore, we have observed that some of the techniques implemented by this group are unconventional, and there is an element of sophistication to them. We believe the authors behind this malware are from Chinese origin. We have labeled the undetected Linux.Antd variants, Linux.GreedyAntd and classified the threat actor as Pacha Group.

COM XSL Transformation: Bypassing Microsoft Application Control Solutions (CVE-2018-8492)

Introduction

Greetings, Everyone!  It has been several months since I’ve blogged, so it seems fitting to start the New Year off with a post about two topics that I thoroughly enjoy exploring: Application Control/Application Whitelisting (AWL) and the Component Object Model (COM).  As the title suggests, I stumbled upon a technique for bypassing Microsoft Application Control solutions using COM. In a particular case, the technique executes unsigned code to bypass Windows Defender Application Control (WDAC)/Device Guard, including PowerShell Constrained Language Mode (CLM) with an Extensible Stylesheet Transformation (XSLT).  In this post, we will discuss the following:

  • Brief Overview of Microsoft AWL Solutions
  • Brief Overview of PowerShell With Constrained Language Mode
  • Walkthrough of CVE-2018-8492 (WDAC Bypass via COM XSLT)
  • Defensive Considerations

while doing some forensics ...

... using Autopsy I found out, that analysing multiple data images is not suported by the program. After a while of thinking, I found the reason lyaing in the simple-sql being used with the tool that creates a deadlock when using it in analysing multiple images.

So the solution was to setup a "multi user environment" using postgres in the background.

So I started with first setting up a central repository as this wil provide the postgresql needed for the multi user as well.

Hackers KO Malta's Bank of Valletta in attempt to nick €13m


by: By Gareth Corfield 13 Feb 2019 at 17:38

In a statement reported by various local outlets, Maltese prime minister Joseph Muscat told parliament that the attack was detected shortly after the start of business today – and involved assailants, said to be from "overseas", trying to transfer €13m to a variety of banks spread across the UK, US, Czech Republic and Hong Kong.

The bank's website, BOV.com, is inaccessible at the time of writing. Even the domain's nameservers appear to have been wiped, judging from the results of multiple domain lookups attempted by The Register.

And some people still ask me why we need expensive (cyber) security at all ...
I guess the amount the damage costs would have rectified some security on the forehand.

The Collective

We are a small group, but our reach expands far beyond just our members, not all of who are listed or ever acknowledged by their own preference. We have informally worked together for many years and have developed deep connections in the field of data gathering, research, journalism, activism and technology. In 2018, we decided to pool together our expertise and time to create a unified project representing our shared goals, and provide a platform for others to know and trust.

The modern state of “leaking” organizations has detoriorated rapidly for many years, poisoned by their own egos and interests. Our view is that data is a resource and a record - this data can never tell the whole story. We trust the public to be responsible with data, and open it to them for the rigorous examination of it. In time, the truth can always emerge.

Sophos KB: Resolving outbreaks of Emotet and TrickBot malware

Sophos released a good writing about EMOTET.

The basic avoidence of EMOTET infections come to:

  1. Secure all of your machines
  2. Patch early, patch often
  3. Block PowerShell by default

Overview

This article is designed to help Sophos customers who have detections for the Emotet or TrickBot malware. While these two malware families are different, often networks infected with one will also have the other as well. This is primarily due to Emotet spreading across a network and additionally downloading TrickBot as it goes. These two threats are very advanced and fast moving, they also use different techniques to achieve their goals and removing both of these involves taking the same actions. In this article, we cover the basic points worth knowing about these threats, how to remove them and how to improve your security to help prevent getting infected again in the future.

28th Januarry: European Data Protection Day

Even those who have "nothing to hide" should protect their privacy

January 28, 2019
They talk to a friend in a café. Suddenly, the waiter asks what your phone numbers are, who your friends are and what you are talking about. Do you provide information? Would you post the information if, in return, you did not have to pay the bill? Do you have something to hide if you do not respond to this trade?

Internet users who voluntarily disclose their privacy to free online services often do so, citing that they have "nothing to hide". However, this point of view is untenable. Having nothing to hide may be a desirable state of affairs, but it is fundamentally different from giving up your privacy.

Not informing the waiter does not mean that you have something to hide but that you want to preserve the privacy you deserve. You may be talking about something banal, but you simply do not think the matter concerns the waiter. In addition, you do not know what the waiter could do with the information or where his interest comes from.

Those who do not unknowingly disclose personal information to unknown persons in everyday life should certainly not do that towards online services. Combining different data sources makes it easy to draw a detailed picture of the users, which may reveal much more about them than they would like.

Today is the European Data Protection Day. Protect your privacy, e.g. With

France will engage in offensive cyber warfare

 

I guess this will start a controverse discussion about this way of "fighting fire with fire" philosophy....

France will engage in offensive cyber warfare

French defence secretary Florence Parly announced that France will engage in a policy of using “cyber arms as all other traditional weapons… to respond and attack" (The Register).

It's a significant statement in an area that governments have often been leery of admitting to and is likely to prompt a shift in international discussion and rhetoric on cyber warfare. Meanwhile, French diplomat Jean Heilbronn has suggested that online espionage should be treated as business as usual by international governments, much as its physical equivalent currently is.

Despite of the educational aspect of such doing, sadly the bad guys abuse this action already in the wild. Everything can be used in good and bad ways. I think A. Einstein mentioned something like that.

But as the actual source is available, it will be an excellent example for security analysts to analyse the bot and create mature detectors to alert of such activity found in your network.

Metasploit Framework 5.0 Released!

 announced the new release of Metasploit 5.0 with some cool additions.

The following is a high-level overview of Metasploit 5.0’s features and capabilities.

  • Metasploit users can now run the PostgreSQL database by itself as a RESTful service, which allows for multiple Metasploit consoles and external tools to interact with it.

  • Parallel processing of the database and regular msfconsole operations improves performance by offloading some bulk operations to the database service.

  • A JSON-RPC API enables users to integrate Metasploit with additional tools and languages.

  • This release adds a common web service framework to expose both the database and the automation APIs; this framework supports advanced authentication and concurrent operations. Read more about how to set up and run these new services here.

  • Adds evasion module type and libraries to let users generate evasive payloads without having to install external tools. Read the research underpinning evasion modules here. Rapid7’s first evasion modules are here.

  • The metashell feature allows users to run background sessions and interact with shell sessions without needing to upgrade to a Meterpreter session.

  • External modules add Metasploit support for Python and Go in addition to Ruby.

  • Any module can target multiple hosts by setting RHOSTS to a range of IPs, or by referencing a hosts file with the file:// option. Metasploit now treats RHOST and RHOSTS as identical options.

  • An updated search mechanism improves Framework start time and removes database dependency.

Twitter leak or #BTLEAK

During the end of 2018, just bevore christmas, the germany partys have got a fancy gift from santa via some tweets, promissing valuable information of several prominent politicians of the german parliament.

Although twitter, google and other bigger institutions tried their best to hide the actual information, but the network is designed to overcome an atomic desaster, so hiding is hard within an environment that never forgets.

By the time of writing, I was still able to use some caches and crawler to get me the actual information and follow the several URL's (669) within the head documents.

I'm still busy with reading and evaluating the information so far, but from the first and second sight, it looks not like the very, very finest information. But, it shows how unprofessional and childish polititians use their data.

Never the less of the quality of the information itself, it is an fantastic source of information for trust relationsships that can be used in phishing and are excellent for social engineering. I*m sure further attacks from turla etc. will use it as a valuable tool.
