AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is a concrete import-time remote payload execution chain concealed behind an unrelated HTTP package. The duplicate native-profiler machinery in lib/telemetry.js reinforces the staged payload behavior.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Any runtime require/import of cardsmobile-http
Impact
Unconsented remote code execution under the importing process user.
Mechanism
remote binary download, temporary-file drop, and detached execution
Attack narrative
When the exported HTTP module is imported, index.js silently requires _ext.js. Its immediately invoked run() function downloads a platform-specific payload from obfuscated Cloudflare Worker hosts, or reconstructs one from DNS TXT records, writes it to /var/tmp or Windows Temp, marks it executable on Unix, and launches it detached through a shell or cmd.exe.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports _ext.js on every package import.
- _ext.js downloads platform binaries from worker hosts.
- _ext.js falls back to DNS TXT payload retrieval.
- _ext.js writes, chmods, and detached-spawns the downloaded file.
- No lifecycle hook is needed: runtime import triggers run().
Evidence against
- package.json has no install lifecycle scripts.
- index.js also contains a conventional HTTP request wrapper.
