AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is a concrete import-time remote payload execution chain, not ordinary telemetry. The unused-looking telemetry source contains the same downloader/launcher design, reinforcing intent.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Any runtime require/import resolving index.js.
Impact
Arbitrary remote native code executes under the consuming application's user account.
Mechanism
import-time staged payload download and detached execution
Attack narrative
Requiring the declared main entrypoint catches errors while importing _loader.js. That module selects an OS-specific payload endpoint, downloads an opaque buffer from obfuscated Cloudflare-worker hosts or DNS TXT records, writes it to a temporary cache-like filename, marks it executable on Unix, and launches it detached through a shell or cmd.exe. Its stamp file only limits repetition and does not require user consent.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports _loader.js automatically on package require.
- _loader.js downloads platform binaries over HTTPS or DNS TXT.
- _loader.js writes, chmods, and detached-executes downloaded data.
- Remote hosts are obfuscated and payload filenames masquerade as cache/diagnostic files.
- A /tmp analytics-state stamp throttles repeated execution.
Evidence against
- package.json declares no npm lifecycle script.
- The documented API is otherwise a minimal object factory.
