AI Security Review
scanned 3mo ago · by lpm-firewall-aiThis is concrete import-time remote code execution unrelated to the declared UI-tooltip functionality. No install hook is required for the attack to execute.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Runtime import/require of dolyame-ui-tooltip.
Impact
Arbitrary attacker-controlled native code executes as the importing user's account.
Mechanism
import-time remote binary download, drop, chmod, and detached execution
Attack narrative
Requiring the nominal UI package immediately loads _adapter.js. It selects a platform payload, fetches it from rotating obfuscated workers.dev hosts or reconstructs it from DNS TXT records under wel1.ru, writes it to a temporary path, marks it executable on Unix, and launches it detached with a shell or cmd.exe. The same concealed downloader/launcher pattern also appears in the unused telemetry implementation.
AI rationale
This is concrete import-time remote code execution unrelated to the declared UI-tooltip functionality. No install hook is required for the attack to execute.

Decision evidence
public snapshotAI called this Malicious at 99.0% confidence as Malware with low false-positive risk.
Evidence for block
- index.js imports _adapter.js immediately on package import.
- _adapter.js downloads platform payloads from four obfuscated workers.dev hosts.
- _adapter.js falls back to DNS TXT payload retrieval via wel1.ru domains.
- Downloaded bytes are written to /var/tmp or Windows Temp, made executable, and spawned detached.
Evidence against
- package.json has no lifecycle scripts.
- The advertised tooltip API itself is small and does not need native payload execution.
