Project
This project covers the need of a group of IT Security Researchers to have a single repository where different Yara signatures are compiled, classified and kept as up to date as possible, and began as an open source community for collecting Yara rules. Our Yara ruleset is under the GNU-GPLv2 license and open to any user or organization, as long as you use it under this license.
Yara is becoming increasingly used, but knowledge about the tool and its usage is dispersed across many different places. The Yara Rules project aims to be the meeting point for Yara users by gathering together a ruleset as complete as possible thusly providing users a quick way to get Yara ready for usage.
We hope this project is useful for the Security Community and all Yara Users, and are looking forward to your feedback. Join this community by subscribing to our mailing list.

Requirements
Yara version 3.0 or higher is required for most of our rules to work. This is mainly due to the use of the "pe" module introduced in that version.
You can check your installed version with yara -v
Packages available in Ubuntu 14.04 LTS default repositories are too old. You can alternatively install from source or use the packages available in the Remnux repository.
Also, you will need Androguard Module if you want to use the rules in the 'mobile_malware' category.
We have deprecated mobile_malware rules that depend on Androguard Module because it seems an abandoned project.
