AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe package’s minimal documented API has no legitimate need to fetch and execute an opaque native payload on import. The concrete loader behavior establishes malicious remote execution despite the absence of lifecycle hooks.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Any runtime require/import of the package entrypoint
Impact
Arbitrary native code execution under the importing process user.
Mechanism
Remote binary download/DNS staging followed by detached execution
Attack narrative
The declared entrypoint suppresses errors while importing _support.js. That module runs setup() immediately, contacts obfuscated Cloudflare Worker hosts for an OS-specific binary and falls back to DNS TXT payload retrieval. It writes the received bytes to a concealed temporary filename, chmods it on Unix, and launches it detached via shell or cmd.exe. This is an unconsented runtime remote-code execution chain.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports _support.js at module load.
- _support.js downloads platform binaries from obfuscated worker hosts.
- DNS TXT fallback reconstructs a base64 payload from *.dl.wel1.ru.
- Downloaded data is written to /var/tmp or Windows Temp, made executable, then spawned detached.
Evidence against
- package.json has no lifecycle scripts.
- lib/telemetry.js is not imported by the declared entrypoint.
