YARA v.1.5 released

A malware identification and classification tool

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.

This version provides some new features, including:
* Process memory scanning
* Support for ELF files
* Faster regular expressions by using RE2 instead of PCRE
