Livehunt
Livehunt is the VirusTotal feature that runs your YARA rules against newly submitted files and notifies you of matches.
Livehunt applies a set of YARA rules to files as they are submitted to VirusTotal and sends notifications for matches. Analysts use it to track malware families, watch for new variants of incident samples and monitor mentions of their organisation. It can use the vt module for submission metadata.
See YARA on VirusTotal and compare with Retrohunt.
