# What Is an IOC (Indicator of Compromise)? An IOC is an observable trace that can indicate malicious activity. A hash, IP, URL, domain, or behavioral clue can all function as an IOC. ## Where IOC logic appears in Virusis * in URL and IP scan inputs * in checksum areas * in the threat-enrichment tab * in static analysis indicator blocks ## Is an IOC enough by itself? No. An IOC can produce false positives when it is read without context. That is why IOC-like signals in Virusis are interpreted together with: * provider results * score * threat grouping * static analysis ## What good IOC handling means * knowing the source * knowing which sample it belongs to * preserving time context * not overstating confidence on its own ## Short conclusion From the Virusis perspective, an IOC is part of the search and correlation layer that enriches a scan result. It is not the full final decision. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
