AI Security Review

scanned 10d ago · by lpm-firewall-ai

Importing the package triggers an unconsented remote payload downloader. It persists a temporary binary and executes it detached.

Static reason

High-risk behavior combination matched malicious policy.; source matched previously finalized malicious package; routed for review

Trigger

Runtime require/import of dolyame-ui-utils

Impact

Remote code execution with the importing process user's privileges.

Mechanism

remote binary download, temporary-file write, chmod, and detached shell execution

Attack narrative

index.js suppresses errors while requiring _polyfill.js. That module runs setup at import time, retrieves a platform-specific payload over HTTPS or reconstructed DNS TXT records, stores it in /var/tmp or Windows Temp, makes it executable on Unix, and starts it detached through a shell or cmd.exe.

Rationale

This is concrete import-time remote payload execution, not legitimate utility behavior. The lack of an npm lifecycle hook does not mitigate runtime execution on require.
