@openzeppelin-5/contracts is a malicious npm package published by npm account `mssjeep843` that impersonates OpenZeppelin's `@openzeppelin/contracts` (the v5 line) via the look-alike scope `@openzeppelin-5`, 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.

The bundle is POSTed to a hardcoded webhook.site endpoint (path 326b0891-2093-4800-a4c1-686ce3e07b09) via a detached child process spawned with a randomized 60–240 second delay to outlive install-time scanning windows. A hostname regex (/^(scan-|detonation|sandbox|ubuntu-fc-uvm)/i) throws early on known sandbox/scanner hosts as anti-analysis gating.
