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:linux_generic_ipv6_catcher
Author:@_lubiedo
Description:ELF samples using IPv6 addresses
Rule name:Linux_Generic_Threat_3bcc1630
Author:Elastic Security
Rule name:Linux_Trojan_Gafgyt_28a2fe0c
Author:Elastic Security
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.
