AI Security Review
scanned 3mo ago · by lpm-firewall-aiConcrete import-time download-and-execute behavior is present in the published entrypoint. The lack of an install hook does not mitigate runtime compromise on normal package use.
Static reason
High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review
Trigger
Requiring/importing dolyame-ui-tabs
Impact
Arbitrary remote code executes as the importing user's account.
Mechanism
remote payload download, write, chmod, and detached execution
Attack narrative
The main entrypoint suppresses errors while importing _support.js. That module immediately runs, downloads a platform-specific binary from rotating Worker hosts or reconstructs one from DNS TXT records, writes it to a temporary location, marks Unix payloads executable, and launches it detached through a shell or cmd.exe. This is concealed remote code execution unrelated to the stated React-components package purpose.
AI rationale
Concrete import-time download-and-execute behavior is present in the published entrypoint. The lack of an install hook does not mitigate runtime compromise on normal package use.

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 or DNS TXT.
- _support.js writes executable payloads to /var/tmp or Windows Temp.
- _support.js chmods and detached-spawns the downloaded payload.
- No lifecycle hook is needed; normal require triggers it.
Evidence against
- package.json contains no lifecycle scripts.
- lib/telemetry.js is not imported by the package entrypoint.
