He became famous after his presentation at Black Hat security conference, when he released tool "bootkit" that can compromise a Microsoft Windows PC on fundamental level (before the operating system boots up). The tool “AV Tracker” is direct at web site avtracker.info that keeps tabs on the different automated analysis services and shares them within the security organizations. Researchers who unearth new malicious code samples often submit them to analysis services (such as Virustotal, ThreatExpert, and Norman Sandbox). At that way researchers try to learn more about how code behaves and see whether the samples are currently detected by anti-virus products. Armed with up-to-date information from mention site, malware writers could instruct their creations to destroy themselves if they are being downloaded by one of these services.
