This report shows the evidence for grafeno-utils@1.0.0, the only known version.
AI Security Review
scanned 2mo ago · by lpm-firewall-aiThis is a concrete install-time remote-code-execution and persistence chain unrelated to the package's exported utilities. The package should be blocked.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
npm installation, before the package is installed
Impact
An attacker controlling the remote host can run arbitrary commands on the installing machine and retain recurring execution.
Mechanism
Preinstall remote shell execution and cron persistence
Attack narrative
During installation, the preinstall command invokes curl for a script hosted at 216.126.236.46 and pipes it into a Bash shell. It then rewrites the current user's crontab to execute the same remote script every 30 minutes. Both actions run without an explicit user command and suppress errors. The package's JavaScript entry point does not require this behavior.
AI rationale
This is a concrete install-time remote-code-execution and persistence chain unrelated to the package's exported utilities. The package should be blocked.

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 remote shell script and immediately runs it with Bash.
- The same automatic hook adds a cron entry that reruns the remote script every 30 minutes.
- Errors are deliberately ignored, reducing visibility of the failed or successful actions.
Evidence against
- The runtime entry point only exports two identity-style utility functions.
- No benign install-time setup is present to justify the remote execution or cron persistence.

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