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:AutoIT_Compiled
Author:@bartblaze
Description:Identifies compiled AutoIT script (as EXE). This rule by itself does NOT necessarily mean the detected file is malicious.
Rule name:DebuggerCheck__API
Reference:https://github.com/naxonez/yaraRules/blob/master/AntiDebugging.yara
Rule name:SUSP_Imphash_Mar23_3
Author:Arnim Rupp (https://github.com/ruppde)
Description:Detects imphash often found in malware samples (Maximum 0,25% hits with search for 'imphash:x p:0' on Virustotal) = 99,75% hits
Reference:Internal Research
