This report shows the evidence for @biz44/id12-client@1.1.13, the only known version.
AI Security Review
scanned 1mo ago · by lpm-firewall-aiThe package establishes an import-triggered detached process that fetches and executes remotely supplied code. This is concrete remote code execution and persistence-like behavior, not a transparent package feature.
Static reason
One or more suspicious static signals were detected.; source matched previously finalized malicious package; routed for review; source fingerprint signature matched known malicious package; routed for review
Trigger
Importing @biz44/id12-client, or explicitly loading loader.js.
Impact
The endpoint operator can run arbitrary Node.js code in the importing user's environment and leave a background process running.
Mechanism
Detached remote payload loader using HTTPS, base64 decoding, and Function execution.
Attack narrative
When an application imports the package, index.js calls initialize. That function starts loader.js detached with hidden standard streams and writes a PID marker. The loader fetches JSON from api.npoint.io, base64-decodes its code field, and invokes it through Function with Node module loading available. This gives a remote endpoint operator arbitrary code execution in the consumer environment without an explicit user action beyond importing the package.
AI rationale
The package establishes an import-triggered detached process that fetches and executes remotely supplied code. This is concrete remote code execution and persistence-like behavior, not a transparent package feature.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- Importing the main entry immediately initializes the client.
- Initialization launches loader.js as a detached background Node process and records its PID.
- The loader downloads a base64 code field from a remote endpoint.
- The downloaded code is executed with require and module context, enabling remote code execution.
Evidence against
- package.json has no npm install lifecycle hook.
- The inspected source does not explicitly collect credentials or upload local data.

This report applies to @biz44/id12-client@1.1.13.
The versions list below shows the verdict for each recorded version.
- Avoid installing @biz44/id12-client@1.1.13. 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.
