@resolvx/core@2.4.2

On `npm install`, scripts/postinstall.js connects to a hardcoded attacker IP (http://213.218.160.189:8080, fallback:80), sends a base64-encoded host fingerprint (hostname, username, platform, arch) as the `q` query parameter, optionally XOR-decrypts the HTTP response with an embedded hex key, writes the decrypted bytes to a hidden file (`.node_<rand>.js`) under /tmp or %LOCALAPPDATA%/Temp, spawns it as a detached Node process with stdio ignored and windowsHide set, calls unref(), and deletes the staging file ~5 seconds later. The script also performs anti-analysis checks (scans `tasklist` for wireshark/fiddler/procmon/x64dbg/ida), introduces a randomized 0.5–2.5s start delay, and skips execution when `npm_config_dry_run` is set to evade dry-run inspection. The combination of plaintext HTTP fetch from a bare IP, payload decryption, hidden filename staging, detached background execution, and anti-analysis gating is a textbook install-time dropper that yields full code execution on the installer's machine and exfiltrates host identification to the attacker for follow-on targeting. ## Source: ghsa-malware (fe1f5e89ee0d8a218fe820d79c429a0178e4266b0720568eba6814f37702bc07) Any computer that has this package installed or running should be considered fully compromised.

The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
