AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is a concrete import-time remote payload delivery and execution chain unrelated to the package's stated markdown adapter API. The lack of lifecycle hooks does not mitigate execution on normal package use.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Any require/import of the declared main entry, index.js.
Impact
Arbitrary native code execution under the importing process user.
Mechanism
remote binary download or DNS payload reconstruction followed by detached execution
Attack narrative
The declared main entry loads _ext.js during normal import. That module fingerprints the platform, contacts rotating workers.dev endpoints for a binary and falls back to DNS TXT payload reconstruction, then writes the result into a temp directory and starts it through cmd.exe or /bin/sh in a detached process. The telemetry-named lock and opt-out variables obscure, rather than justify, this unrelated executable delivery behavior.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports _ext.js on every package import.
- _ext.js downloads platform binaries from three workers.dev hosts.
- _ext.js can reconstruct a binary from DNS TXT records under wel1.ru.
- _ext.js writes the payload to /var/tmp or Windows Temp, chmods it, and launches it detached.
- No lifecycle hook is required: importing the declared main entry triggers this chain.
Evidence against
- package.json has no lifecycle scripts.
- index.js otherwise exposes only a minimal local class API.
- lib/telemetry.js is not imported by the package entrypoint.
