AI Security Review

scanned 10d ago · by lpm-firewall-ai

Importing the declared main entrypoint automatically loads a concealed downloader. It retrieves an OS-specific payload, writes it to temporary storage, and executes it detached.

Static reason

High-risk behavior combination matched malicious policy.

Trigger

Any require/import of dolyame-ui-select.

Impact

Arbitrary remote code execution as the importing process user.

Mechanism

Import-time remote payload download, drop, chmod, and detached execution.

Attack narrative

The public entrypoint silently requires _bridge.js. On import, its main routine fetches an OS-specific binary from obfuscated Workers hosts, falling back to DNS TXT-record payload assembly. It writes the result to a temporary executable path, grants execute permission on non-Windows systems, and starts it detached through a shell or cmd.exe. The package's documented UI purpose does not justify this behavior.

Rationale

This is a concrete, automatic import-time remote-code-execution chain, not merely telemetry functionality. Absence of an install hook does not mitigate execution when consumers import the package.
