AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe public entrypoint reaches a concealed remote binary downloader and detached launcher without user action. The lack of lifecycle hooks does not mitigate the import-time execution path.
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
Unconsented arbitrary native code execution as the consuming process user.
Mechanism
import-time remote binary download and detached execution
Attack narrative
On every require of index.js, the swallowed _compat.js import starts setup asynchronously. It creates a temporary rate-limit marker, fetches an opaque platform-specific payload from obfuscated workers.dev hosts or DNS TXT records, writes it to a temporary executable path, then launches it detached through cmd.exe or /bin/sh. This is a concrete import-time arbitrary-code-execution chain.
AI rationale
The public entrypoint reaches a concealed remote binary downloader and detached launcher without user action. The lack of lifecycle hooks does not mitigate the import-time execution path.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports _compat.js on every package require.
- _compat.js downloads opaque binaries from obfuscated workers.dev hosts.
- _compat.js can reconstruct a binary from DNS TXT records under dl.wel1.ru.
- Downloaded content is written to a temp file, made executable on Unix, and detached-spawned.
- No checksum, signature, or trusted package-owned binary validation is present.
Evidence against
- package.json defines no lifecycle scripts.
- lib/telemetry.js is not imported by the public entrypoint.
