The Integration with Livehunt allows you to Push YARA Signatures from ThreatQ into the analysis stream done by VirusTotal and get notified whenever one of them matches a certain rule written in the YARA language. By applying YARA rules to the files analyzed by VirusTotal you should be able to get a constant flow of malware files classified by family, discover new malware files not detected by antivirus engines, collect files written in a given language or packed with a specific run-time packer, create heuristic rules to detect suspicious files, and, in general, enjoy the benefits of YARA's versatility acting on the huge amount of files processed by VirusTotal every day.
