Validate YARA rule syntax and structure for malware detection patterns.
YARA rules are pattern-matching signatures used by malware analysts and antivirus engines to identify and classify files. This tool checks a rule's basic structure — required sections and syntax — entirely in your browser.
YARA lets analysts write rules describing textual or binary patterns characteristic of malware families. A rule has three parts: meta (descriptive info), strings (the patterns to search for), and condition (the logic for when the rule matches).
This is a structural syntax check, not a full YARA engine — it confirms the rule has the expected shape (keyword, braces, sections) but doesn't execute the rule against real files or validate every condition expression. For production use, validate rules with the official yara CLI or library.
