## What is MAL-2026-15849?

MAL-2026-15849 is a malicious package in @quantixfinance/common, published on 3 Sep 2026. 

### Official description

The package's preinstall lifecycle script iterates process.env and collects any variable whose name matches a broad list of secret-shaped substrings (key, secret, token, pass, mnemonic, seed, private, wallet, api, rpc, infura, alchemy, database, supabase, vercel, railway, and others), bundles the matches with hostname, cwd, and Node version, and POSTs the JSON payload to a hardcoded destination written as the 32-bit integer 759017974 (decoding to 45.61.169.70) on port 61289. The numeric-integer form of the hostname evades trivial IP/URL string scanners. The behavior fires automatically on `npm install`, so any environment with wallet mnemonics, cloud credentials, or CI tokens in its environment will have those values shipped to the hardcoded endpoint before any package code is otherwise used.

## What should I do about MAL-2026-15849?

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