It’s also interesting to note that each time PClock2 scans a directory or encrypts a file, it makes an HTTP POST request to the C2 server.


Unfortunately, this specific string is not completely unique to x4k, and is instead found on several GitHub repositories as part of a technique to allow a running executable to delete itself from disk through renaming primary data streams within the file to :wtfbbq.

Typically, attacks against the kernel are used in conjunction with code execution attacks so that an attacker can target a limited privilege user but ultimately gain full control over the system.


Meanwhile, the vulnerabilities we found on the configuration attack surface can be abused to affect the DDS developer or system integrator, potentially compromising the integrity of the software supply chain.

We did not capture the subsequent stages, but assess the attackers did not have exploits for the current version of Chrome (91.0.4472) at that time, but instead used n-day exploits targeting Samsung Browser, which was running an older and vulnerable version of Chromium.


Since the string “ConfuserEx v1.0.0-custom” is present in the module property: [module: KurdishCoderProducts("ConfuserEx v1.0.0-custom")]”, we can surmise that the version of ConfuserEx that was used for CyaX_Sharp was indeed built outside of Git.

The only malicious activity we have seen in our telemetry related to SpringShell involves HTTP requests to URLs containing the tomcatwar.jsp filename associated with the SpringShell proof-of-concept script.


On the same taskbar, we also noticed the Telegram icon, which is a very popular messaging app for chatting – but is also used by threat actors such as LAPSUS$ to post news into specific channels.


The actions to take in response to this event are clear and simple:  As always, we will continue to watch this event closely and provide any updates that we can.

We are actively collaborating with our partners in industry and governments to share our analysis and findings based on our global threat telemetry network.


As this functionality has not migrated outside the Allaple family, either the quality of the code is bad (see: face rolling), or it's simply not available to other malware developers.  The fifth is very likely as a change to the specific functionality these mutexes protect, with every change to any functionality, is simply not a practical method of development.


The attacks we found all arrived through targeted emails (MITRE ATT&CK framework ID T1193).

Method B: Self modifying the APK  This exploit can take advantage of the same vulnerability to mask what permissions the app really requires.  This vulnerability affects Android device users as well as Android app developers.  For Android device users, the users may end up with installing apps that are not the ones they agree to install.  Android app developers are also affected, because app-store apps and mobile ads libraries that do not rely on Google Play store would be likely to save the promoted apps in unprotected storage, e.g. /sdcard.
