HackTool Named File Stream Creation
This rule detects the creation of a named file stream (Alternate Data Stream - ADS) containing specific Imphash values associated with known hack tools. The Imphash values are for tools such as Mimikatz, PetitPotam, JuicyPotato, RoguePotato, Pwdump, Cobalt Strike beacons, NanoDump, HandleKatz, DripLoader, UACMe, Dumpert, EDRSandBlast, and others. Adversaries often use ADSs to hide malicious executables or data to evade detection by traditional security tools that may not scan alternate data streams.
