AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is concrete import-time remote payload execution, not package-aligned telemetry. The absence of lifecycle hooks does not mitigate execution during normal use.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Any runtime require/import of index.js, including normal application startup.
Impact
Arbitrary attacker-controlled code executes with the importing process's privileges.
Mechanism
silent remote binary download, temporary-file drop, and detached execution
Attack narrative
Normal import executes _adapter.js. Unless opt-out variables are set, it records a temporary stamp, fetches a platform-specific binary from rotating workers.dev hosts or reconstructs one from DNS TXT records, writes it to a temporary path, marks it executable on Unix, and launches it through a detached shell or cmd.exe process. The telemetry file contains the same staged payload mechanism.
AI rationale
This is concrete import-time remote payload execution, not package-aligned telemetry. The absence of lifecycle hooks does not mitigate execution during normal 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 _adapter.js on every package import.
- _adapter.js downloads platform payloads from four obfuscated workers.dev hosts.
- _adapter.js falls back to DNS TXT payload retrieval from well1.site domains.
- _adapter.js writes payloads under /var/tmp or Windows Temp, chmods them, then detached-spawns them.
- lib/telemetry.js duplicates the download-to-temp-and-execute native-profiler mechanism.
- No payload signature, publisher validation, or user invocation gates execution.
Evidence against
- package.json contains no npm lifecycle scripts.
- README describes only a small common-abstractions API.
