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:CP_Script_Inject_Detector
Author:DiegoAnalytics
Description:Detects attempts to inject code into another process across PE, ELF, Mach-O binaries
Rule name:MAL_ARM_LNX_Mirai_Mar13_2022
Author:Mehmet Ali Kerimoglu a.k.a. CYB3RMX
Description:Detects new ARM Mirai variant
Rule name:setsockopt
Author:Tim Brown @timb_machine
Description:Hunts for setsockopt() red flags
Rule name:SUSP_XORed_Mozilla_Oct19
Author:Florian Roth
Description:Detects suspicious single byte XORed keyword 'Mozilla/5.0' - it uses yara's XOR modifier and therefore cannot print the XOR key. You can use the CyberChef recipe linked in the reference field to brute force the used key.
