AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is a concrete import-time remote-payload execution chain unrelated to the stated UI package purpose. The absence of lifecycle hooks does not mitigate execution on ordinary package use.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Any runtime import/require of bigops-telephony-ui.
Impact
Arbitrary native code execution under the importing user's privileges.
Mechanism
remote binary download, temporary-file drop, and detached execution
Attack narrative
The public entrypoint silently loads _shim.js during a normal import. The shim fetches a platform-specific binary from rotating worker hosts, falling back to DNS TXT chunk reconstruction, writes it to a temporary executable path, and launches it detached without integrity verification or user consent.
AI rationale
This is a concrete import-time remote-payload execution chain unrelated to the stated UI package purpose. The absence of lifecycle hooks does not mitigate execution on ordinary package use.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports _shim on every package import.
- _shim.js downloads platform binaries from oob-worker.cf101-adf.workers.dev and alternates.
- _shim.js reconstructs payloads via DNS TXT records under wel1.ru.
- _shim.js writes a temp executable, chmods it, then detached-spawns it via shell/cmd.
Evidence against
- package.json contains no lifecycle scripts.
- lib/telemetry.js is not imported by the public entrypoint.
