VirusTotal Hunting is a powerful service that allows users to proactively search VirusTotal's extensive malware database using YARA rules and retro-hunting capabilities. Unlike traditional antivirus solutions that rely on signature-based detection, VirusTotal Hunting enables users to define custom rules to identify malware based on patterns, strings, or other characteristics. This allows security professionals to uncover previously unknown malware variants, track the evolution of existing threats, and identify targeted attacks. The service essentially transforms VirusTotal from a passive analysis platform into an active threat hunting tool. This proactive approach is critical for staying ahead of adversaries and mitigating potential risks. For more information on YARA rules, you can read about it here.
