@quantixfinance/commonnpm
@quantixfinance/common is a confirmed malicious npm package (MAL-2026-15849) that steals credentials and exfiltrates sensitive data (malicious version 1.0.0). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in @quantixfinance/common (npm)
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.

Detection & response playbook
Credential / info stealerFind it
Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for @quantixfinance/common (version 1.0.0). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging @quantixfinance/common across your stack and pipelines.
If you installed it — respond
@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.
Did it already run?
If @quantixfinance/common was ever installed, its post-install/runtime payload may have already executed. O3's L7 egress monitoring and runtime eBPF sensors detect the credential exfiltration or command-and-control callback after install and block the malicious outbound channel, so you catch and contain the actual compromise — not just the presence of the package.
How O3 protects you
O3 blocks @quantixfinance/common before install through its supply-chain scanner, and if it has already run, detects and severs the exfiltration or C2 callback at runtime through L7 egress monitoring and eBPF.

O3 blocks @quantixfinance/common-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
