Deepfence YaRadare aka “Ya-Radar” which scans container photos, operating Docker containers, and filesystems to search out indicators of malware by using YARA ruleset and scans the assets to determine the presence of malware and the level of compromise.

In the cloud native environment, it can be used in flowing methods

  • At relaxation: scan native container photos, earlier than they’re deployed, to confirm they don’t include malware
  • At runtime: scan operating docker containers, if, for instance, you observe uncommon community site visitors or CPU exercise
  • Towards filesystems: at any time, YaRadare can scan an area listing or filesystem for indicators of compromise

YaRadare is fully open supply (Apache v2 license) and can be used with variety of other YARA rulesets.


YaRadare Roadmap

  • Provide-Chain Poisoning: a malicious actor injects malware into upstream photos. A developer unwittingly consists of these photos in software builds, and the ensuing construct artifacts are deployed to manufacturing or shipped to different customers.
  • Malicious Deployment: a consumer compromises the deployment means of a software, for instance, by making a malicious admission controller or init script that injects malware into an software picture when it’s deployed.
  • Run-Time Compromise: an attacker exploits a vulnerability or weak configuration in a operating software, akin to log4j, to put in malware instruments.

YaRadare will function inside 4 levels of the lifecycle of a software picture:

Lifecycle Stage: Construct and Take a look at

  • Functionality: CI/CD integration. Look at photos throughout construct to determine any malware-like parts inside
  • Function: To detect and block Provide Chain Poisoning
  • Standing: Backlog

Lifecycle Stage: Containers at Relaxation

  • Functionality: Scan container photos ‘at relaxation’, supporting varied private and non-private registries
  • Function: Detect proof of Provide Chain Poisoning
  • Standing: Supported for native containers (pulled from distant registry); Backlog: direct scanning of containers in distant registries

Lifecycle Stage: At Deployment

  • Functionality: Kubernetes Admission Controller (or equal). Examine workloads in the intervening time of deployment and block photos that don’t meet requirements
  • Function: Last backstop for Provide Chain Poisoning checks; determine some cases of malicious deployment
  • Standing: Backlog

Lifecycle Stage: At Runtime

  • Functionality: Examine operating containers for the presence of malware-like parts
  • Function: Detect run-time compromise
  • Standing: Assist for Docker (filesystem photos); Backlog: assist for Kubernetes; Backlog: in-memory scanning

Few points on the backlog are tagged as “assist wanted”, for which the contribution is required

YaRadare in Motion

Construct YaRadare

YaRadare is a self-contained docker-based device, hosted at Clone this repository, then construct:

docker construct –rm=true –tag=deepfenceio/deepfence-yaradare:newest
-f Dockerfile .

Discover Indicators of Compromise in a container picture

Photographs could also be compromised by the setup of a variety of various malware software program instruments. One frequent compromise entails the setup of a cryptominer akin to XMRig, permitting the attacker to amass compute cycles for the needs of mining cryptocurrency.


By scanning a legitimate cryptominer picture that incorporates the same XMRig software program to that which is commonly put in by way of an exploit:

This returns, amongst different issues, clear indication of the presence of XMRig. Be aware that we retailer the output (/tmp/xmrig-scan.json) for fast and straightforward manipulation:

This returns an inventory of attainable IOCs recognized within the container we scanned.
