YARA is a tool aimed at helping malware researchers to identify and classify malware samples.
With YARA you can create descriptions of malware families based on textual or binary patterns contained on samples of those families. Each description consists of a set of strings and a Boolean expression which determines its logic.
YARA is multi-platform, running on Windows, Linux and Mac OS X, and can be used through its command-line interface or from your own Python scripts with the yara-python extension.
New in version 1.3:
- C-style include directives
- Rules can contain metadata information
- Multiple files/sources can be compiled at once in yara-python.
