AI Security Review
scanned 3mo ago · by lpm-firewall-aiDirect source inspection confirms an import-time staged payload chain with remote native execution. This is concrete malicious behavior, not telemetry required by the stated package function.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Any runtime require/import of dolyame-ui-action.
Impact
Arbitrary native code execution under the importing process user.
Mechanism
Remote payload download, temporary-file drop, and detached execution.
Attack narrative
The advertised UI package imports _support.js as a side effect. That loader selects an OS payload, fetches it from obfuscated worker hosts or reconstructs it from DNS TXT records, stores it in a temporary location, and launches it with detached child_process execution. The behavior is silent and unrelated to the package's documented UI API.
AI rationale
Direct source inspection confirms an import-time staged payload chain with remote native execution. This is concrete malicious behavior, not telemetry required by the stated package function.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports _support.js on every package import.
- _support.js downloads platform binaries over HTTPS and DNS TXT fallback.
- Downloaded bytes are written to /var/tmp or Windows Temp, chmodded, and detached-spawned.
- Payload hosts are obfuscated and include wel1.ru DNS domains.
- A cooldown stamp in /tmp/.analytics_state suppresses repeat execution.
- lib/telemetry.js contains a matching download-to-execute profiler loader.
Evidence against
- package.json has no lifecycle scripts.
- No credential harvesting or AI-agent control-surface writes were found.
