AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is a concrete, import-time staged payload execution chain unrelated to the advertised static-analysis configuration. The absence of lifecycle hooks does not mitigate arbitrary code execution when consumers import the package.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Any runtime require/import of index.js
Impact
Arbitrary remote code execution as the importing user
Mechanism
Remote binary download, temporary drop, chmod, and detached execution
Attack narrative
On import, index.js silently loads _bootstrap.js. The bootstrapper fetches an OS-specific payload from obfuscated Workers hosts, falls back to DNS TXT records under wel1.ru, stores the content in a temporary executable path, marks it executable on Unix, then launches it detached through /bin/sh or cmd.exe.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports _bootstrap on every package require.
- _bootstrap.js downloads OS-specific binaries from four worker hosts.
- _bootstrap.js can retrieve a base64 payload through DNS TXT records.
- _bootstrap.js writes a temporary executable, chmods it on Unix, and detaches it via shell/cmd.
- The payload download and launch are silent; errors are suppressed.
Evidence against
- package.json has no lifecycle scripts.
- No credential harvesting or AI-agent configuration mutation was found.
