# About

## What is this?

A repo containing some of my privately developed Yara rules.

## Why?

To contribute to the community.

## Can I use these rules?

Of course! That's why I created this repo. 

You can use them in your detection systems. For example, [CAPE sandbox](https://github.com/kevoreilly/CAPEv2), [MalwareBazaar](https://bazaar.abuse.ch/), [UnPac.me](https://www.unpac.me/) and [VirusTotal](https://www.virustotal.com/) (must be logged in, signup is free) and others are using these rules. Furthermore, the rules can work natively with [AssemblyLine](https://www.cyber.gc.ca/en/tools-services/assemblyline) due to the CCCS Yara rule standard adoption.

All rules are TLP:White, so you can use and distribute them freely. Please retain the meta. 

## Help! A generic rule is hitting my software!

If one of the rules in the [generic](https://github.com/bartblaze/Yara-rules/tree/master/rules/generic) rules section hits on your software: this is not a false positive. It is simply an objective fact that, for example, your software has been compiled or wrapped using AutoIT. It equally does **not** mean your software is malicious. 

The Yara rules presented here do **not** influence antivirus detection results in any manner. If your software is detected by an antivirus or antimalware company, **you need to contact them directly**.

Note the `meta` section also mentions `category = "INFO"`, in which case it is a purely generic or informational rule.

## Actions

There's two workflows running on this Github repository:

* [YARA-CI](https://yara-ci.cloud.virustotal.com/): runs automatically to detect signature errors, as well as false positives and false negatives.

* [Package Yara rules](https://github.com/bartblaze/Yara-rules/blob/master/.github/workflows/yara.yml): allows download of a complete rules file (all Yara rules from this repo in one file) for convenience from the Actions tab > Choose the last workflow run > Artifacts. Scroll down and you will be able to download, but you must be logged in to Github:

## Minimum Yara version needed?

**v3.3.0** is minimally needed, as some rules may require a specific module. Note that it's recommended to always use the latest Yara version as found [here](https://github.com/VirusTotal/yara/releases). Yara 4.5.1, likely the last release to be available, works without issue.

## Do the rules work with Yara-X?

[Yara-X](https://github.com/VirusTotal/yara-x), a rewrite of Yara in Rust, should have no difficulty running the rules in this repo. At time of writing, Yara-X v0.6.0 works fine with the rules presented here.

## Feedback?

If you spot an issue or improvement with one of the rules, feel free to submit a PR or open an Issue.
