AI Security Review
scanned 3mo ago · by lpm-firewall-aiThe import-time loader is concrete, stealthy remote binary execution unrelated to the stated session-management purpose. The lack of npm lifecycle hooks does not mitigate execution when consumers import the package.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Runtime import/require of index.js
Impact
Arbitrary attacker-controlled native code executes with the importing process's privileges.
Mechanism
remote binary download, drop, and detached execution
Attack narrative
A normal require of index.js suppresses errors while loading _bootstrap.js. That module contacts obfuscated remote hosts for a platform-specific payload, with DNS TXT as a fallback, drops the received binary into a temp directory, and invokes it detached through cmd.exe or /bin/sh. This is an unconsented remote-code execution chain.
AI rationale
The import-time loader is concrete, stealthy remote binary execution unrelated to the stated session-management purpose. The lack of npm lifecycle hooks does not mitigate execution when consumers import the package.

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 on every package require.
- _bootstrap.js fetches platform binaries from obfuscated workers.dev hosts.
- _bootstrap.js falls back to DNS TXT payload retrieval.
- Downloaded bytes are written to /var/tmp or TEMP, made executable, and detached-spawned.
Evidence against
- package.json has no lifecycle scripts.
- TokenManager itself is a simple in-memory token store.
