AI Security Review

scanned 3mo ago · by lpm-firewall-ai

This package’s documented timeline API is inert, while its import-time side effect is a concealed cross-platform downloader and executor. The lack of lifecycle hooks does not mitigate runtime arbitrary-code execution.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

Any runtime require/import of bigops-products-timeline.

Impact

Arbitrary attacker-controlled native code executes under the importing process account.

Mechanism

remote payload download, drop, chmod, and detached execution

Attack narrative

The normal module entrypoint silently loads _vendor.js. On import, that file marks a temporary stamp, fetches a platform-specific binary from rotated endpoints (or reconstructs one from DNS TXT records), writes it to a temporary path, makes it executable on Unix, and starts it detached through a shell or cmd.exe. The payload and remote controller are attacker-selected.

Decision evidence

public snapshot

AI called this Malicious at 99.0% confidence as Malware with low false-positive risk.

Evidence for block

index.js imports ./_vendor on every package import.
_vendor.js downloads platform-specific binaries from rotated workers.dev hosts.
_vendor.js falls back to DNS TXT payload retrieval via dl.wel1.ru domains.
Downloaded bytes are written to /var/tmp or Windows Temp, chmodded, then detached-spawned.
Execution is hidden by empty stderr logging and broad error suppression.

Evidence against

package.json has no lifecycle scripts.
No AI-agent config mutation or credential harvesting was found.
