The npm package dolyame-ui-tooltip, advertised as a UI tooltip component, contains malicious code that downloads and executes opaque binaries from obfuscated remote hosts. The package uses obfuscation techniques to hide network destinations and execution of child processes, which is unusual for a UI tooltip library. This behavior enables full-host remote code execution during installation. Only version 35.8.8 is explicitly identified as affected. No official patch or remediation guidance is provided yet.
