The npm package 'streak-map-cache' version 1.0.0 contains malicious code that executes a bundled Linux ELF binary acting as a RedShell command-and-control implant. This binary runs on every import, communicates with a hardcoded C2 server over HTTP, and supports remote shell commands, proxying, file exfiltration, credential harvesting, and persistence. The malicious binary is disguised as a 'native math accelerator' to evade detection. Any system with this package installed should be considered fully compromised.
