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_AllMal_Detector
Author:DiegoAnalytics
Description:CrossPlatform All Malwares Detector: Detect PE, ELF, Mach-O, scripts, archives; overlay, obfuscation, encryption, spoofing, hiding, high entropy, network communication
Rule name:ELF_Mirai
Author:NDA0E
Description:Detects multiple Mirai variants
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.
