@openzeppelin-5/contracts @1.0.1

Summary

Package name typosquats @openzeppelin/contracts. package.json declares both preinstall and postinstall as node index.js || true , so the payload auto-executes on npm install . index.js harvests process.env entries matching KEY|TOKEN|SECRET|MNEMONIC|WALLET|AWS|GITHUB|NPM and reads installer-side credential files including ~/.aws/credentials, ~/.ssh/id_rsa, ~/.ssh/id_ed25519, ~/.kube/config, ~/.docker/config.json, ~/.netrc, ~/.npmrc, ~/.git-credentials, gcloud/solana/sui/foundry keystores, and local.env files. 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.
