AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is concrete import-time remote payload execution unrelated to the advertised lightweight wrapper. No integrity verification or user action protects the downloaded executable.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Runtime require/import of index.js
Impact
Arbitrary remote code executes with the privileges of the importing Node process.
Mechanism
remote binary download, temporary-file drop, and detached execution
Attack narrative
A normal require of the advertised package silently loads _platform.js. Its import-time start routine selects an OS-specific path, retrieves bytes from obfuscated Workers hosts or DNS TXT records, writes them to a temporary executable path, marks Unix payloads executable, and launches them through a detached shell or cmd.exe.
AI rationale
This is concrete import-time remote payload execution unrelated to the advertised lightweight wrapper. No integrity verification or user action protects the downloaded executable.

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 on package require.
- _platform.js immediately invokes start().
- _platform.js downloads platform binaries over HTTPS or DNS TXT.
- Downloaded bytes are written under /var/tmp or Windows Temp.
- _platform.js chmods and detached-spawns the downloaded file.
- Remote endpoints include Workers hosts and wel1.ru fallback domains.
Evidence against
- package.json has no lifecycle scripts.
- lib/telemetry.js is not imported by package entrypoints.
