Malicious code in @antv/f6-alipay (npm)
The npm account `atool` was compromised and used to publish 631 malicious versions across 314 npm packages, including @antv/f6-alipay, as part of the "Mini Shai-Hulud" supply chain attack campaign. 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/f6-alipaynpm package compromised with malicious preinstall hook
A threat actor compromised the npm account atool and published 631 malicious versions across 314 npm packages in an automated 22-minute burst. This incident is part of the "Mini Shai-Hulud" supply chain attack campaign. The @antv/f6-alipay package was among the affected packages.
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 to steal 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. Stolen credentials are committed to attacker-controlled repositories following Dune-themed naming patterns.
The attack 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 compromise was confirmed by multiple security sources including Amazon Inspector and Google Open Source Security.
Indicators of compromise
- Packages
- @antv/f6-alipay
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/f6-alipay to a known-clean version prior to the attack
- Audit CI/CD workflows for unauthorized `Run Copilot` workflow or other suspicious workflow modifications
- Search for and remove any `kitty-monitor` system daemons from affected systems
- Review GitHub repository commits for suspicious activity and attacker-controlled repositories with Dune-themed names
- Implement npm package integrity verification and consider using npm audit to identify other compromised packages from the 314 affected
- Monitor for unauthorized access patterns and credential usage in AWS, GitHub, GCP, Azure, and other cloud services
