YARA is the name of a tool primarily used in malware research and detection.

It provides a rule-based approach to create descriptions of malware families based on textual or binary patterns. A description is essentially a YARA rule name, where these rules consist of sets of strings and a boolean expression.[1] The language used has traits of Perl compatible regular expressions.[2][3]


YARA was originally developed by Victor Alvarez of VirusTotal, and released on GitHub in 2013.[4] The name is either an abbreviation of YARA: Another Recursive Acronym, or Yet Another Ridiculous Acronym.[5]


YARA by default comes with modules to process PE, ELF analysis, as well as support for the open-source Cuckoo sandbox.
