What is MAL-2026-15851?
MAL-2026-15851 is a malicious package in @quantixfinance/contracts, published on 3 Sep 2026.
Official description
The package's preinstall lifecycle script iterates process.env and filters keys for credential-shaped substrings (key, secret, token, pass, mnemonic, seed, private, wallet, rpc, infura, alchemy, api), attaches os.hostname(), process.cwd() and process.version, and POSTs the resulting JSON to a hardcoded remote host. The destination is written as an integer literal (759017974, decoding to 45.61.177.246) on port 61289 to evade string-based scanners. The package advertises itself as a contracts/ABI library and has no legitimate need to read or transmit environment secrets or host identifiers.
What should I do about MAL-2026-15851?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
