  "details": "js-logger-pack is a fake npm logger that the attacker developed openly on the registry over 23 versions across two weeks (2026-04-01 to 2026-04-15). Version 1.1.20, published hours after initial detection, is a re-obfuscation of the same payload with a new hash \u2014 same C2, same capabilities. Early versions were harmless probes; version 1.1.5 introduced the first weaponized payload with unobfuscated TypeScript source that accidentally leaked the attacker\u2019s SSH RSA public key (bink@DESKTOP-N8JGD6T) and their original C2 domain (api-sub.jrodacooker[.]dev). Subsequent versions replaced the readable source with a 885 KB custom base64 bytecode VM and swapped the domain for a raw Hetzner IP. The payload is a long-running WebSocket agent that: installs the attacker\u2019s RSA key into ~/.ssh/authorized_keys on Linux; exfiltrates Telegram Desktop tdata sessions; drains credentials from 27 crypto wallets and Chromium-family browsers; steals .npmrc, cloud provider tokens, and shell history; and runs a native keylogger on Windows, macOS, and Linux with autostart persistence on all three.\n\n---\n_-= Per source details.
