The npm package tinkoff-boxy-gitlab-labels version 20.5.4 contains malicious code that downloads and executes a native binary payload from obfuscated Cloudflare Workers hosts. The payload is saved to temporary directories under disguised filenames and executed silently, potentially compromising the host system. This behavior includes evasion techniques such as runtime hostname reconstruction and periodic execution control. Any system with this package installed should be considered fully compromised.
