Summary
Malicious code in streak-metricazbd (npm)
Details
On import of the package, dist/index.mjs runs an IIFE that copies a bundled Linux x86_64 ELF (dist/math-core.bin) to /tmp/sm-engine-runtime/math-core.bin and spawns it via child_process.spawn, framed as 'math-core engine calibration' and wrapped in an error-swallowing try/catch. The dropped binary is a full remote-access implant identifying itself as 'RedShell': it beacons to a hardcoded remote server at 217.60.77.63, accepts commands over that channel to execute arbitrary shell commands via /bin/sh and /bin/bash, provides SOCKS5 proxying and TCP port forwarding, downloads and executes additional ELF/shellcode payloads, installs systemd --user persistence disguised as 'svc-update.service', and exposes /ssh_keys, /creds, /dbfind, /env, /dataextract, and /download commands that harvest installer SSH keys, credentials, and arbitrary files and exfiltrate them in chunks via POST /api/extract-receive. Any host that imports this package hands full remote control and credential access to the operator of 217.60.77.63.
