AI Security Review
scanned 3mo ago · by lpm-firewall-aiSource inspection confirms an import-time downloader and detached payload launcher, not just suspicious primitives. The absence of lifecycle hooks does not mitigate execution on normal import.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Any Node.js require/import resolving index.js.
Impact
Arbitrary attacker-supplied native code executes with the importing process user's privileges.
Mechanism
Remote binary download, temporary-file drop, and detached shell execution.
Attack narrative
A consumer merely requiring the advertised event-bus package executes index.js, which silently loads _ext.js. That module selects a platform payload URL, retrieves a blob from rotating concealed hosts or DNS TXT records, writes it to a temporary path, makes it executable on Unix, and starts it detached via /bin/sh or cmd.exe. This is an unconsented remote-code-execution chain unrelated to the documented API.
AI rationale
Source inspection confirms an import-time downloader and detached payload launcher, not just suspicious primitives. The absence of lifecycle hooks does not mitigate execution on normal import.

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 during normal package require.
- _ext.js downloads OS-specific payloads from concealed workers.dev hosts.
- _ext.js falls back to DNS TXT payload retrieval from well1.site domains.
- Downloaded data is written to /var/tmp or Windows Temp, chmodded executable, then detached-spawned.
- The advertised event-bus API does not require or document this native payload behavior.
- lib/telemetry.js contains a parallel download-to-temp-and-execute capability.
Evidence against
- package.json has no npm lifecycle scripts.
- No source evidence of credential harvesting or AI-agent configuration writes.
