TGI HUNT - Update January 2024

Hey all, I’ve decided to start being more verbose about this project’s activity in the hope of generating more feedback from people checking it out.


Documentation will slowly appear in the ruleset as reference links to this site. If there is a particular rule you’d like to know more about, simply open a github issue here and I will bump it to the top of the doumentation queue.

Ruleset Housekeeping

  • cleaned up spacing
  • removed some obsolete encoding rules
  • renamed & simplified 2610338
  • removed previously disabled JA3 rules

New Rules

xmrigCC Donation Mining Pool Domain

I found this domain while examining torminer. It is a hardcoded domain found in xmrigCC source code

Suspicious String Inbound (b64 DownloadString)

This was found analyzing malicious powershell downloading an exe file per CrackMapExec web delivery of implant

Powershell.exe Inbound to SQL (UTF-16LE)

This was found surveying MSSQL attack techniques in Metasploit and CrackMapExec

MSSQL Antivirus Error

This error was observed during adversary simulation against MSSQL, when the MSSQL antivirus found something naughty and refused the query/command

Malicious Shell Script Artifact Inbound

These artifacts were observed when a compromised system reached out for a script containing these lines, which are meant to disable command logging at the bash terminal. For example PEASS-ng, a local privesc utility, uses this technique.

MSSQL Configuration Changed Message

This is the output of sp_configure MSSQL stored procedure, which occurs when using any of the Metasploit techniques to execute on MSSQL.

MSSQL Blocked Stored Procedure Message

Observed in MSSQL when using Metasploit

Server blocked access to procedure ‘sys.xp_cmdshell’ of component ‘xp_cmdshell’ because this component is turned off as part of the security configuration for this server. A system administrator can enable the use of ‘xp_cmdshell’ by using sp_configure. For more information about enabling ‘xp_cmdshell’, search for ‘xp_cmdshell’ in SQL Server Books Online.

MSSQL Generic xp_cmdshell

This is a generic xp_cmdshell string observed across many red team github repos

Base64 Encoded EXE File in DNS

This came up in my daily reading, and I found an example from the venerable Didier Stevens. Note that I didn’t specify TXT record type here.
