Overview
knot-date-utils-rb is a malicious package.
This package is part of a malicious cluster of Ruby gems published by the threat actor knot-theory. Designed to impersonate legitimate utilities, it executes a payload upon installation that harvests environment variables, SSH keys, AWS credentials, and configuration files.
Stolen data is exfiltrated to an external endpoint, specifically targeting developer systems and CI environments. All versions are compromised and should be removed immediately.
Note: While earlier versions may have appeared benign to evade detection, the maintainer's intent was malicious, and all versions should be considered compromised.
