Malicious code in @antv/x6-angular-shape (npm)
The npm account `atool` was compromised and used to publish 631 malicious versions across 314 npm packages, including @antv/x6-angular-shape, in an automated 22-minute burst. Each malicious version injects a preinstall hook executing an obfuscated Bun script that exfiltrates credentials and establishes persistence via CI/CD workflow injection and system daemons.

- @antv/x6-angular-shapenpm package compromised with malicious preinstall hook
A threat actor compromised the npm account atool and published 631 malicious versions across 314 npm packages as part of the "Mini Shai-Hulud" supply chain attack campaign. The @antv/x6-angular-shape package was among those compromised, modified to include a malicious preinstall hook.
Each malicious version executes a 498KB obfuscated Bun script that exfiltrates sensitive credentials including AWS keys, GitHub PATs, npm tokens, GCP service accounts, Azure credentials, Kubernetes service account tokens, SSH keys, Docker auth configs, database connection strings, Stripe keys, and Slack tokens. The script uses the GitHub API as a covert exfiltration channel, committing stolen data to attacker-controlled repositories following Dune-themed naming patterns (e.g., harkonnen-melange-742).
Beyond credential theft, the malicious payload establishes persistence through multiple mechanisms: CI/CD workflow injection (a GitHub Actions workflow named Run Copilot that dumps all secrets via toJSON(secrets)), AI agent session hooks, and a system daemon named kitty-monitor. The attack was executed in an automated 22-minute burst, indicating a coordinated, large-scale compromise.
Indicators of compromise
- Packages
- @antv/x6-angular-shape
Remediation
- Immediately revoke all credentials (AWS keys, GitHub PATs, npm tokens, GCP service accounts, Azure credentials, Kubernetes tokens, SSH keys, Docker auth configs, database credentials, Stripe keys, Slack tokens) that may have been exposed
- Remove or downgrade @antv/x6-angular-shape to a known-clean version prior to the malicious publication
- Audit npm account `atool` and all packages it maintains for additional compromises
- Review GitHub Actions workflows for unauthorized `Run Copilot` workflows or other suspicious CI/CD modifications
- Check systems for the `kitty-monitor` daemon and remove if present
- Monitor for unauthorized access to exfiltrated credentials and services
- Enable MFA on all npm, GitHub, AWS, GCP, Azure, and other critical accounts
- Review npm package dependencies for other packages from the 314 affected packages in this campaign
