@openzeppelin-4/contracts is a malicious npm package published by npm account `mssjeep843` that impersonates OpenZeppelin's `@openzeppelin/contracts` (the v4 line) via the look-alike scope `@openzeppelin-4`, falsely describing itself as a "compatibility distribution". It ships no Solidity contracts — only an install-time payload (index.js) run via preinstall/postinstall that harvests credential-shaped environment variables and reads and exfiltrates SSH private keys, cloud credentials (AWS/GCP/Kubernetes/Docker), Solana/Anchor/NEAR/Sui wallet keys, Foundry keystores, `.git-credentials` and local `.env` files to `https://webhook.site/326b0891-2093-4800-a4c1-686ce3e07b09`. It is one of a series of DeFi/crypto impersonation packages from the same account sharing this webhook.site endpoint, which also squat Aerodrome Finance, Camelot AMM, Euler EVC, BoringVault and Uniswap Permit2. --- _-= Per source details.

Delivery uses spawn(process.execPath, ['-e', src], { detached: true, stdio: 'ignore' }) with a randomized 60–240 second delay, and the script bails out when the hostname or username matches sandbox/scanner patterns (scan-, detonation, sandbox, ubuntu-fc-uvm) or when canary env markers are present, evading install-time analysis.
