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 Create hunting rule
Author:	DiegoAnalytics
Description:	Detects attempts to inject code into another process across PE, ELF, Mach-O binaries

Rule name:	F01_s1ckrule Create hunting rule
Author:	s1ckb017

Rule name:	linux_generic_ipv6_catcher Create hunting rule
Author:	@_lubiedo
Description:	ELF samples using IPv6 addresses

Rule name:	SUSP_XORed_Mozilla_Oct19 Create hunting rule
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.
