What is MAL-2026-16300?
MAL-2026-16300 is a malicious package in @baanx/solana-lib, published on 21 Sep 2026.
Official description
The package declares scripts.install = node index.js, so npm install @baanx/solana-lib automatically executes index.js, which loads lib/core.js. That module reads the installer's username (os.userInfo().username), hostname (os.hostname()), and current working directory basename, concatenates them with a timestamp and the static prefix bxsol, and issues a dns.resolve4() lookup against <prefix>.<user>.<host>.<cwd>.<ts>.oob.algamil7x.xyz — a DNS-based out-of-band beacon that leaks installer identity to a hardcoded non-first-party domain. Helper modules lib/e5f0a2.js and lib/f6a1b3.js reconstruct the strings os, dns, userInfo, hostname, cwd, resolve4, the prefix bxsol, and the destination host oob.algamil7x.xyz from String.fromCharCode byte arrays, and load Node builtins indirectly via module.constructor._load('os') / _load('dns') to conceal the behavior. The package is presented as a Solana library; the char-code-obfuscated destination and the install-time host-recon beacon are inconsistent with any legitimate Solana functionality.
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-2026-16300?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
