YARA File Scanner
Live Engine · Real YARAScan a file with real YARA rules, or write and test your own
Upload any file. This runs the real, open-source YARA pattern-matching engine (the industry standard AV/EDR/threat-intel teams use to write and share detection rules) against it — either a small built-in educational rule set, or a YARA rule you write yourself.
This never executes the uploaded file — pure pattern matching over raw bytes, capped at 5MB. Every result is a real matched rule with real evidence, never a fabricated malicious/clean verdict.
