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:BLOWFISH_Constants
Author:phoul (@phoul)
Description:Look for Blowfish constants
Rule name:ELF_Toriilike_persist

Description:Detects Torii IoT Botnet (stealthier Mirai alternative)
Reference:Identified via researched data
Rule name:SHA512_Constants
Author:phoul (@phoul)
Description:Look for SHA384/SHA512 constants
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.
