AI Security Review
scanned 3mo ago · by lpm-firewall-aiDirect source inspection confirms a reachable import-time downloader and executor, not merely telemetry behavior. The lack of install hooks does not mitigate runtime execution on package import.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Runtime require/import of boxy-demo-tokens
Impact
Arbitrary remote code execution under the importing process user.
Mechanism
Obfuscated remote payload download/DNS fallback followed by temp-file execution
Attack narrative
On module import, index.js loads _bridge.js. The bridge selects an OS-specific endpoint, downloads a payload from obfuscated hosts or reconstructs one from DNS TXT records, writes it into a temporary directory, makes it executable on Unix, and launches it detached through a shell or cmd.exe. This is an unconsented remote-code-execution chain; the bundled telemetry module contains a parallel payload-extension mechanism.
AI rationale
Direct source inspection confirms a reachable import-time downloader and executor, not merely telemetry behavior. The lack of install hooks does not mitigate runtime execution on package import.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports ./_bridge during every module load.
- _bridge.js downloads platform payloads from obfuscated workers.dev hosts.
- _bridge.js falls back to DNS TXT payload retrieval from wel1.ru domains.
- _bridge.js writes the downloaded payload to /var/tmp or Windows Temp, marks it executable, and spawns it.
- No integrity check or signature verification is performed before execution.
Evidence against
- package.json has no lifecycle scripts.
- index.js token manager itself is an in-memory token utility.
