YARA Signatures


MalwareBazaar uses YARA rules from several public and non-public repositories, such as YARAhub and Malpedia. Those are being matched against malware samples uploaded to MalwareBazaar as well as against any suspicious process dumps they may create. Please note that only results from TLP:CLEAR rules are being displayed.

Rule name:Check_Debugger
Rule name:CP_Script_Inject_Detector
Author:DiegoAnalytics
Description:Detects attempts to inject code into another process across PE, ELF, Mach-O binaries
Rule name:DebuggerCheck__API
