grafeno-auth
Auth module for Grafeno
This report shows the evidence for grafeno-auth@1.0.0, the only known version.
AI Security Review
scanned 2mo ago · by lpm-firewall-aiSource inspection confirms an automatic install hook that fetches and executes a remote payload, then establishes cron persistence. This is concrete malicious install-hook abuse.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
npm preinstall during package installation.
Impact
An attacker controlling the remote host can run arbitrary commands on the installing machine and retain recurring execution.
Mechanism
Remote shell execution followed by cron persistence.
Attack narrative
The preinstall lifecycle hook invokes curl for a script hosted at 216.126.236.46 and pipes the response into a shell. It then edits the current user's crontab to execute that same remote script every 30 minutes. Both actions occur without a user command beyond installation and suppress errors, enabling remote code execution and persistence.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- A preinstall hook downloads a shell script from 216.126.236.46 and pipes it to Bash.
- The same automatic hook adds a cron job that reruns the remote script every 30 minutes.
- Errors are silently ignored, concealing failed execution or persistence attempts.
Evidence against
- index.js only exports a minimal login stub and has no harmful import-time behavior.
