## What is MAL-2026-2827?

MAL-2026-2827 is a malicious package in js-logger-pack, published on 15 Apr 2026. 

### Official description

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 — 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’s 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’s 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.

The package js-logger-pack was found to contain malicious code.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. 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.

## What should I do about MAL-2026-2827?

Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
