grafeno-client
HTTP client for Grafeno APIs
This report shows the evidence for grafeno-client@1.0.0, the only known version.
AI Security Review
scanned 2mo ago · by lpm-firewall-aiDirect source inspection confirms an automatic install hook that executes an unverified remote script and creates cron persistence. The benign-looking runtime stub does not mitigate this install-time attack.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
npm installation activates the preinstall lifecycle hook.
Impact
An attacker controlling the remote payload can execute arbitrary commands and retain recurring execution on the installing host.
Mechanism
Remote shell execution followed by cron persistence.
Attack narrative
The package runs a shell command during preinstall that pipes a script fetched from 216.126.236.46 into Bash. It then alters the user's crontab to repeat that download-and-execute command every 30 minutes. This provides remote code execution and persistence before the package's normal runtime API is used.
AI rationale
Direct source inspection confirms an automatic install hook that executes an unverified remote script and creates cron persistence. The benign-looking runtime stub does not mitigate this install-time attack.

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 and executes a remote shell script without user action.
- The same hook adds a cron job that re-downloads and executes the remote script every 30 minutes.
- Errors are suppressed, which hides failed download and persistence attempts.
Evidence against
- The runtime entry point is an inert minimal HTTP-client stub.
- No additional package source files were present.

Affected versions and remediation
This report applies to grafeno-client@1.0.0.
The versions list below shows the verdict for each recorded version.
- Avoid installing grafeno-client@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.
