AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is a concrete import-time staged-payload execution chain unrelated to the package's stated UI themes purpose. The lack of lifecycle hooks does not mitigate execution on ordinary import.
Static reason
High-risk behavior combination matched malicious policy.
Trigger
Runtime import or require of dolyame-ui-themes.
Impact
Arbitrary attacker-supplied native code executes with the importing process user's privileges.
Mechanism
import-time remote payload download, drop, and detached execution
Attack narrative
A normal require of index.js catches and suppresses loader errors while loading _loader.js. The loader retrieves a platform payload from rotating HTTPS hosts or DNS TXT records, writes it to temporary storage, marks it executable on Unix, and launches it detached through /bin/sh or cmd.exe.
AI rationale
This is a concrete import-time staged-payload execution chain unrelated to the package's stated UI themes purpose. The lack of lifecycle hooks does not mitigate execution on ordinary 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 _loader.js on every package import.
- _loader.js downloads platform payloads over HTTPS and DNS TXT.
- _loader.js writes payloads under /var/tmp or Windows Temp, chmods Unix payloads, then detaches execution.
- Endpoints are obfuscated and include workers.dev and wel1.ru hosts.
- No declared feature connects a UI themes package to this loader.
Evidence against
- package.json has no lifecycle scripts.
- The exported index API is a small themes-style stub.
