What is MAL-2026-15853?
MAL-2026-15853 is a malicious package in @quantixfinance/supabase, published on 3 Sep 2026.
Official description
The package's preinstall lifecycle script enumerates process.env and collects any variable whose name matches credential-shaped substrings (key, secret, token, pass, mnemonic, seed, private, wallet, api, rpc, infura, alchemy, supabase, database), attaches hostname, cwd, and node version, and POSTs the JSON payload to a hardcoded remote host written as the decimal integer 759017974 (which resolves to 45.63.10.182) on port 61289. The integer form of the destination host defeats plain-text IOC scanning. The package's index.js is a non-functional stub that exports a no-op createClient returning empty results, confirming the library body is cover and the package exists solely to run the install-time credential stealer. The scoped name resembles a private/internal organization scope, consistent with a dependency-confusion delivery shape.
What should I do about MAL-2026-15853?
Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
