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 regular expression, 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]
YARA was originally developed by Victor Alvarez of VirusTotal, and released on GitHub in 2013.[2] The name is an abbreviation of YARA: Another Recursive Acronym or Yet Another Ridiculous Acronym.[3]
YARA by default comes with modules to process PE, ELF analysis, as well as support for the open-source Cuckoo sandbox.
