---------------------------------------------
Transparent Tribe, also known as PROJECTM and MYTHIC LEOPARD, is a highly prolific group whose activities can be traced as far back as 2013. Proofpoint published a very good article about them in 2016, and since that day, we have kept an eye on the group. [...] The USBWorm component is real, and it has been detected on hundreds of systems. This is malware whose existence was already speculated about years ago, but as far as we know, it has never been publicly described.

∗∗∗ IBM Db2 Shared Memory Vulnerability (CVE-2020-4414) ∗∗∗
---------------------------------------------
I’ve recently blogged about a shared memory vulnerability in Cisco WebEx Meetings Client on Windows where any user can read memory dedicated to trace data. It turns out that this is a common problem. IBM Db2 is affected by the exact same type of problem. Developers forgot to put explicit memory protections around the shared memory used by the Db2 trace facility. This allows any local users read and write access to that memory area.

According to researchers at Cado Security this is the first-ever worm that comes with AWS credential theft functionality on top of run-of-the-mill cryptomining modules. This botnet uses already infected servers to execute an open-source masscan IP port scanner instance that scans for exposed Docker APIs (and Kubernetes systems as later discovered), installing itself in new containers on any misconfigured servers it finds.

One of our readers, Lukas, shared an unusual malicious executable with us earlier this week - one that was 130 MB in size. Making executables extremely large is not an uncommon technique among malware authors[1], as it allows them to easily avoid detection by most AV solutions, since the size of files which AVs will check is usually fairly low (tens of megabytes at most).

Dharma, a family of ransomware first spotted in 2016, continues to be a threat to many organizations—especially small and medium-sized businesses. Part of the reason for its longevity is that its variants have become the basis for ransomware-as-a-service (RaaS) operations.

The attribution of cyber attacks is hard. It requires collecting diverse intelligence, analyzing it and deciding who is responsible. Rarely does the evidence available to researchers reach a level of proof that would be acceptable in a court of law. Nevertheless, the private sector rises to the challenge to attempt to associate cyber attacks to threat actors using the intelligence available to them.

∗∗∗ Making the Most Out of WLAN Event Log Artifacts ∗∗∗
---------------------------------------------
If you have taken FOR500 (Windows Forensic Analysis) or utilize the FOR500 "Evidence of..." poster, you are probably familiar with the WLAN Event Log listed under the Network Activity/Physical Location section of the poster. This Windows event log (Microsoft-Windows-WLAN-AutoConfig/Operational) records wireless networks that a system has associated with as well as captures network characteristics that can be used for geolocation. In recent testing involving this artifact, a discovery was made that may have implications for investigators. I will outline a scenario that illustrates the issue and present artifacts to help solve it.

∗∗∗ Bypassing MassLogger Anti-Analysis — a Man-in-the-Middle Approach ∗∗∗
---------------------------------------------
The FireEye Front Line Applied Research & Expertise (FLARE) Team attempts to always stay on top of the most current and emerging threats. As a member of the FLARE Reverse Engineer team, I recently received a request to analyze a fairly new credential stealer identified as MassLogger. Despite the lack of novel functionalities and features, this sample employs a sophisticated technique that replaces the Microsoft Intermediate Language (MSIL) at run time to hinder static analysis.
