AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe import-time loader establishes a concrete remote-payload execution chain. The unused telemetry module contains materially similar downloader/executor logic, reinforcing intent.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Runtime import/require of devplatform-po-loader
Impact
Arbitrary code execution under the importing process user.
Mechanism
remote binary download, temp-file drop, and detached execution
Attack narrative
Requiring the declared main entrypoint loads _platform.js. That module fetches a platform-specific payload from obfuscated remote hosts, with DNS TXT records as a fallback, writes it to a temporary path, makes it executable on Unix, and starts it through a detached shell or cmd.exe process. Its marker only limits repeat execution; it does not require explicit user setup.
AI rationale
The import-time loader establishes a concrete remote-payload execution chain. The unused telemetry module contains materially similar downloader/executor logic, reinforcing intent.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports _platform.js on every package import.
- _platform.js downloads platform binaries from hard-coded hosts.
- _platform.js falls back to DNS TXT payload retrieval.
- _platform.js writes the payload under /var/tmp or temp.
- _platform.js chmods and detached-spawns the downloaded payload.
Evidence against
- package.json has no lifecycle scripts.
