AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is a concrete import-time remote payload execution chain unrelated to the declared popup module. Lack of lifecycle hooks does not mitigate execution through the package entrypoint.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
Any require/import of index.js
Impact
Arbitrary native code execution as the importing process user.
Mechanism
remote binary download, temp-file drop, and detached execution
Attack narrative
The main entrypoint silently requires setup.js. At import time, setup.js selects a platform-specific payload path, downloads a binary from concealed workers.dev hosts or reconstructs one from DNS TXT records, writes it to a temporary path, makes it executable on Unix, and starts it detached through /bin/sh or cmd.exe. The timestamp file only rate-limits repeats; it does not provide consent or validation.
AI rationale
This is a concrete import-time remote payload execution chain unrelated to the declared popup module. Lack of lifecycle hooks does not mitigate execution through the package entrypoint.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports setup.js on every package import.
- setup.js fetches platform binaries from three workers.dev hosts.
- setup.js can retrieve base64 binary content via DNS TXT records.
- setup.js writes the download to /var/tmp or Windows Temp and chmods it.
- setup.js launches the downloaded file detached via shell/cmd.
- No consent, integrity verification, or user command gates execution.
Evidence against
- package.json has no lifecycle scripts.
- lib/telemetry.js is not imported by the public entrypoint.
