Which versions of @quantixfinance/common are malicious?

The following npm versions of @quantixfinance/common are flagged malicious: 1.0.0. Treat any of these as compromised.

How do I remediate @quantixfinance/common if I installed it?

@quantixfinance/common is built to steal secrets, so assume every credential the build or runtime could read is compromised. Remove it from your project and lockfile, then rotate ALL exposed secrets — npm/registry tokens, cloud keys, CI/CD secrets, SSH keys, and any .env values — from a known-clean machine. Audit logs for unauthorized use of those credentials.

I already installed @quantixfinance/common — how do I know if it already compromised me?

If @quantixfinance/common was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

Is @quantixfinance/common part of a known attack campaign?

Yes — @quantixfinance/common is associated with the IN-MAL-2026-019371 campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.

How do I find @quantixfinance/common across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for @quantixfinance/common (version 1.0.0).

What this malware does

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.
