AI Security Review
scanned 11h ago · by lpm-firewall-aiThe main module starts a loop that renames the current package and publishes it publicly with the user's npm credentials. Although the README describes running the script directly, importing the package also triggers publishing without a distinct request.
Static reason
High-risk behavior combination matched malicious policy.; source fingerprint signature matched known malicious package; routed for review
Trigger
Module import or execution of `autopublish.js`; the publishing function is called at top level.
Impact
An import can publish packages using the user's npm credentials and repeatedly change the project's package name and lockfile without a distinct publish request.
Mechanism
The script rewrites package metadata, invokes `npm publish --access public`, then schedules another publish after a random delay.
Attack narrative
The package's main entry points to `autopublish.js`, which immediately changes the current package name, publishes it publicly, and schedules another publish. Importing it can therefore use the user's npm credentials to publish randomized package names and modify project metadata without a separate publish request. The README documents running the script directly, but the main entry also makes the behavior reachable through import.
AI rationale
The main module starts a loop that renames the current package and publishes it publicly with the user's npm credentials. Although the README describes running the script directly, importing the package also triggers publishing without a distinct request.

Decision evidence
public snapshotAI called this Malicious at 95.0% confidence as Malware with low false-positive risk.
Evidence for block
- `package.json` sets `autopublish.js` as the main module, so requiring the package loads the publishing script.
- The script changes the current package name to a random value and writes the change to `package.json` and `package-lock.json`.
- It runs `npm publish --access public` and schedules further publishing after a delay.
- The script calls `publishWithDelay()` at top level, without requiring a separate command or confirmation.
Evidence against
- The README describes a tool for renaming and publishing packages and tells users to run `node autopublish.js` explicitly.
