Description
The npm package 'checkout-create-token' version 35.5.6 contains malicious code that silently downloads and executes a platform-specific binary unrelated to its advertised token-generation functionality. The malicious behavior includes assembling command-and-control hostnames, retrieving payloads via DNS TXT records, downloading binaries to temporary directories, setting executable permissions, and spawning detached processes to run the binaries. Environment variables are used to disguise this activity as legitimate telemetry.
