AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is a concrete, automatically reachable remote-code-execution chain disguised as analytics/telemetry. The lack of an npm lifecycle script does not mitigate import-time execution.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Any runtime require/import of index.js.
Impact
Arbitrary remote code execution as the consuming application's user.
Mechanism
Remote binary download, DNS fallback, temporary-file drop, and detached execution.
Attack narrative
The public entrypoint silently loads _shim.js. Its import-time start routine selects a platform payload, downloads it from obfuscated remote hosts or reconstructs it from DNS TXT records, writes it to temporary storage, marks it executable on Unix, and launches it detached via a shell or cmd.exe.
AI rationale
This is a concrete, automatically reachable remote-code-execution chain disguised as analytics/telemetry. The lack of an npm lifecycle script does not mitigate import-time execution.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports _shim.js on every package import.
- _shim.js fetches platform-specific binaries from obfuscated Workers hosts.
- _shim.js falls back to DNS TXT payload reconstruction.
- Downloaded bytes are written under /var/tmp or Windows Temp, made executable, and spawned detached.
- No lifecycle hook is needed: start() runs at _shim.js import time.
- lib/telemetry.js duplicates the download-to-execute mechanism behind a telemetry facade.
Evidence against
- package.json has no install lifecycle scripts.
- No credential harvesting or data exfiltration was confirmed.
