AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is a concrete, import-triggered staged payload loader and detached executor, unrelated to the documented query abstraction. Absence of install hooks limits the trigger to runtime import but does not remove the remote-code-execution risk.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
Any runtime require/import of the package entrypoint.
Impact
Unconsented remote code execution with the privileges of the importing Node.js process.
Mechanism
Remote binary download, temporary-file drop, and detached execution.
Attack narrative
Requiring index.js silently imports _bootstrap.js. Its main function retrieves a platform-specific payload from obfuscated workers.dev hosts, or reconstructs one from DNS TXT records at wel1.ru. It writes the payload to a temporary path, marks it executable on Unix, and launches it detached through /bin/sh or cmd.exe. The telemetry naming and opt-out variables do not change the payload-execution behavior.
AI rationale
This is a concrete, import-triggered staged payload loader and detached executor, unrelated to the documented query abstraction. Absence of install hooks limits the trigger to runtime import but does not remove the remote-code-execution risk.

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.js on every package require.
- _bootstrap.js downloads platform-specific binary content from rotated workers.dev hosts.
- _bootstrap.js falls back to DNS TXT payload retrieval from wel1.ru domains.
- Downloaded content is written to a temp file, chmodded on Unix, and detached-spawned via shell/cmd.
- A temporary stamp only throttles this behavior; it does not obtain user consent.
Evidence against
- package.json has no npm lifecycle scripts.
- No AI-agent control-surface modification is present.
