119. RustDesk: An RMM You May Not Heard About

Hello everyone!

I'm sure you are well-informed about various RMMs abused by adversaries. But have you heard about this one - RustDesk?

For example, it was used ITW by Akira ransomware affiliates. The tool is available for various platforms, here's a Windows version.

Let's look at some detection opportunities, and start from the binary itself:

event_type: "processcreatewin"

AND

proc_file_productname: "rustdesk"

You may also hunt for file or folder creation events related to RustDesk:

event_type: "filecreate"

AND

file_path: "rustdesk"

Make sure you checked non-Windows binaries as well!

See you tomorrow!

082. Huniting for Malicious Browser Extensions

Image
Hello everyone! Malicious browser extensions are stopping to be an exotic threat. For example,  Rilide . It was first reported in April 2023, but became a common threat, and this report is another proof of it. Can we hunt for such extensions? Of course, yes! For example, usually threats like Rilide modify browser-reated LNK files to run it with " --load-extension " argument, like this: chrome.exe --load-extension="C:\Users\user\AppData\Local\Temp\MalExt" It means we can hunt for execution of common Chromium-based browsers with this argument: event_type: "processcreatewin" AND proc_file_name: ("chrome.exe" OR "brave.exe" OR "opera.exe" OR "msedge.exe")  AND cmdline: "load-extension" I'm sure you'll get false positives, but this is what we expect from threat hunting, right? Proper filtering will help you, I'm sure! See you tomorrow!

Hello everyone! Everybody loves free courses, right? Have you missed a free course on Google Threat Intelligence ? If the answer is "Yes", it's your chance to check it!  I like this course as it not only overviews the capabilities of Google Threat Intelligence as a product, but also covers various threat intelligence use cases, for example, how to empower incident response and forensic investigations or how to use it for adversary hunting and tracking. I've already got my completion badge: What about you? See you tomorrow!

068. Detecting RMMs from Ransomware Affiliate's Toolkit: MeshAgent

Image
Hello everyone! Let's keep talking about ransomware affiliate's toolkit. This time about remote monitoring and management (RMM) software. If you checked the report I shared yesterday, you may noticed the adversary used a number of RMMs. We are going to talk about one of them - MeshAgent. Another example of MeshAgent abuse is Enigma Wolf, you can read about this ransomware gang in this report. As always, we can search for processes with MeshAgent-related metadata: event_type: "processcreatewin" AND (proc_file_originalfilename: "MeshAgent.exe" OR proc_file_productname: "MeshCentral Agent ") Depending on configuration, you may also observe meshcentral[.]com DNS requests: event_type: "dnsreq" AND dns_rname: "meshcentral.com" If your EDR solution collects PDB data, you can use for detection as well: event_type: "processcreatewin" AND proc_file_pdb_path: "MeshAgent" I'm sure you can find event more detection ...
