132. Threat Actors Abuse N‑sight RMM to Attack Brazilian Organizations

Hello everyone!

Adversaries keep showing interest in legitimate tools, especially RMMs. Accoring to Cisco Talos report, the threat actors executed a spam campaign against Brazilian users, weaponizing N‑sight RMM.

It's interesting enough, that N-able also provides security solutions and MDR service. It makes such tools even more trusted. For example, the RMM agent currently has 0 detections on VirusTotal.

For example, we can use product-related metadata to build our hunting query:

event_type: "processcreatewin"

AND

proc_file_productname: "Advanced Monitoring Agent"

Also, you may want to hunt for file creation event in related folders:

event_type: "filecreatewin"

AND

file_path: "Advanced Monitoring Agent"

See you tomorrow!

033. Free Google Threat Intelligence Course

Image
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!

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!

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 ...
