Malicious code in @antv/data-wizard (npm)
The npm account `atool` was compromised and used to publish 631 malicious versions across 314 packages, including @antv/data-wizard. Each 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/data-wizardMalicious preinstall hook injected; part of Mini Shai-Hulud campaign
A threat actor compromised the npm account atool and launched an automated attack publishing 631 malicious versions across 314 npm packages in a 22-minute burst, part of the "Mini Shai-Hulud" supply chain attack campaign. The @antv/data-wizard package was among those compromised.
Each malicious version injects a preinstall hook that executes a 498KB obfuscated Bun script. The script uses the GitHub API as a covert exfiltration channel and commits stolen credentials to attacker-controlled repositories following Dune-themed naming patterns (e.g., harkonnen-melange-742).
Stolen data includes 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 attack establishes persistence through CI/CD workflow injection (a GitHub Actions workflow named Run Copilot that dumps all secrets), AI agent session hooks, and a system daemon named kitty-monitor.
The incident was detected by Amazon Inspector and Google Open Source Security, indicating the malicious packages were identified and the attack contained.
Indicators of compromise
- Packages
- @antv/data-wizard
Remediation
- Immediately audit and revoke all credentials (AWS keys, GitHub PATs, npm tokens, GCP service accounts, Azure credentials, Kubernetes tokens, SSH keys, Docker configs, database credentials, Stripe keys, Slack tokens) that may have been exposed
- Remove all malicious versions of @antv/data-wizard and other affected packages from npm; do not install or update to any version published during the attack window
- Inspect CI/CD workflows for the injected `Run Copilot` GitHub Actions workflow and remove it; audit all workflow logs for unauthorized secret access
- Search systems for the `kitty-monitor` daemon and remove it; check for unauthorized persistence mechanisms
- Review git commit history in attacker-controlled repositories (Dune-themed naming) for exfiltrated credentials
- Rotate all credentials and implement monitoring for unauthorized access patterns
- Update npm account security: enable 2FA, audit authorized applications, and review publish logs
