Update March 22, 13:15 UTC: Wiz Research continues to track TeamPCP activity following the initial Trivy compromise. The threat actor has expanded operations to the npm ecosystem via a worm ("CanisterWorm") leveraging stolen publish tokens. Additionally, the ICP-hosted fallback C2 (tdtqy-oyaaa-aaaae-af2dq-cai) is now actively serving an iteratively developed payload (kamikaze.sh). Aqua has published a blog post and a GitHub Security Advisory.

What happened?

Wiz Research, in concert with other industry parties, identified a multi-faceted supply chain attack targeting Aqua Security's Trivy. The attack compromised multiple components of the Trivy project: the core scanner, the trivy-action GitHub Action, and the setup-trivy GitHub Action.

The attacker also compromised the aqua-bot service account and then abused their access push malicious workflows to tfsec, traceeshark, and trivy-action and steal additional credentials from Aqua (including GPG keys and credentials for Docker Hub, Twitter, and Slack). These secrets were exfiltrated to a Cloudflare Tunnel C2 (plug-tab-protective-relay.trycloudflare.com). Furthermore, 75 out of 76 trivy-action tags were force-pushed to malicious versions, and 7 setup-trivy tags were force-pushed as well. 

The malicious versions of these Actions run a tool self-described as "TeamPCP Cloud stealer", which dumps Runner.Worker process memory, harvests SSH, cloud, and K8s secrets, encrypts the data (using AES-256+RSA-4096), and exfiltrates it to a remote server. The malware is configured to create a repository named tpcp-docs in the victim's GitHub account as a fallback method.

What did the malicious GitHub workflows do?

The attacker injected the same three-stage payload into both trivy-action (in entrypoint.sh) and setup-trivy (in action.yaml). When a downstream workflow executed either action, the payload ran on the victim's GitHub Actions runner:

1. Collection: The malware scraped memory from the Runner.Worker process by reading /proc/<pid>/mem and searching for the pattern {"value":"<secret>","isSecret":true}. It also swept the filesystem for SSH keys, cloud credentials  (AWS, GCP, Azure), Kubernetes tokens, and cryptocurrency wallets across 50+ sensitive file paths.

2. Encryption: Harvested credentials were encrypted using AES-256-CBC with RSA-4096 hybrid encryption and bundled into tpcp.tar.gz

3. Exfiltration: The malware transmitted the encrypted bundle to a typosquatted domain (scan.aquasecurtiy[.]org). As a fallback, it could create a tpcp-docs repository in the victim's GitHub account and upload the stolen credentials  as a release asset.

What did the malicious Trivy binary (v0.69.4) do?

When the malicious binary is executed it starts both the legitimate trivy service and the malicious code in parallel. In our initial analysis the malicious code exfiltrates secrets with a primary and backup mechanism. If it detects it is on a developer machine it additionally writes a base64 encoded python dropper for persistence.

Data Theft

The malicious process gathers environmental variables, sweeps the system for any credentials stored in the filesystem and enumerates the network interface. It then compresses and encrypts the data and attempts to exfiltrate it via post request to https://scan.aquasecurtiy[.]org. If that fails (returns a non-2xx status code), the malware then attempts to use a stolen GITHUB_TOKEN to create a repo tpcp-docs and post the data there. 

Set Persistence

The malicious code attempts to identify if it is on a developer machine by checking if the environmental variable GITHUB_ACTIONS != “true”. If that check passes, the malware attempts to create persistence by writing a python script as ~/.config/systemd/user/sysmon.py and creating a systemd unit that persistently runs the python script.

sysmon.py initially sleeps for five minutes and then polls https://tdtqy-oyaaa-aaaae-af2dq-cai.raw.icp0.io/. If a non-youtube link is found there the dropper downloads to /tmp/pglog and executes it in a new session. 

At the time of analysis (10:30 AM EST/15:30 UTC) the malicious site was set to a RickRoll, but it could be changed by the attacker at any time. 

Which actions should security teams take?

1.  Audit Trivy versions: Check whether your organization pulled or executed Trivy v0.69.4 from any source (GitHub Releases, container registries, etc.). Remove any affected artifacts immediately.

2.  Audit GitHub Action references: Review workflows using aquasecurity/trivy-action or aquasecurity/setup-trivy. If you referenced a version tag rather than a SHA, check workflow run logs from March 19-20 for signs of compromise. Specifically, you can look in the Run Trivy step of trivy-action and the Setup environment step of setup-trivy.

3.  Search for exfiltration artifacts: Look for repositories named tpcp-docs in your GitHub organization, which may indicate successful exfiltration via the fallback mechanism. Hunt based on the IOCs provided below.

Long-term hardening: Pin GitHub Actions to full SHA hashes, not version tags. Version tags can be moved to point at malicious commits, as demonstrated in this attack.

How Wiz can help?

Wiz customers should refer to and monitor the advisory in the Wiz Threat Center for ongoing guidance, pre-built queries, and references to relevant detections they can use to assess the risk  in their environment.
