YaraHunter

Deepfence YaraHunter scans container images, running Docker containers, and filesystems to find indicators of malware. It uses a YARA ruleset to identify resources that match known malware signatures, and may indicate that the container or filesystem has been compromised.

YaraHunter can be used in the following ways:

Key capabilities:

YaraHunter is a work-in-progress (check the Roadmap and issues list), and will be integrated into the ThreatMapper threat discovery platform. We welcome any contributions to help to improve this tool.

Quick Start

For full instructions, refer to the YaraHunter Documentation.

Example: Finding Indicators of Compromise in a container image

Images may be compromised with the installation of a cryptominer such as XMRig. In the following example, we'll scan a legitimiate cryptominer image that contains the same xmrig software that is often installed through an exploit:

Pull the official yarahunter image:

or Build it from source clone this repo and run below command

Scan

Pull the image that needs to be scanned for example metal3d/xmrig and scan it:

Scan the image:

This returns, among other things, clear indication of the presence of XMRig. Note that we store the output (xmrig-scan.json) for quick and easy manipulation:

Rules can also be cached to use next run by mounting a separate path and passing rules-path argument

This returns a list of the IOCs identified in the container we scanned.

To get table formatted output omit --output=json flag
