Node.js repository posing as a ZIP-321 Zcash payment URI builder/parser. Its prepare and postinstall hooks run a credential stealer when the repo is installed as a git dependency. The stealer takes environment variables, SSH private keys, cloud/CI credentials, Keplr MCP wallet vaults, and keychain secrets. The actor behind the malicious lwd-uri-util crate published it. Malicious payload found in: install.js (run by package.json scripts.prepare and scripts.postinstall) Behavior: collects all env vars, hostname, and username; reads ~/.git-credentials, .netrc, .npmrc, .pypirc, .aws/credentials, .aws/config, .ssh/config, .ssh/id_ed25519, .ssh/id_rsa, .ssh/id_ecdsa, .config/gh/hosts.yml, .config/vercel/auth.json, .wrangler/config/default.toml, .keplr-mcp/config.json, .keplr-mcp/vaults.json, .keplr-mcp/vaults/*.enc, .zcash/zcash.conf, .zcash/zcashd.conf, .docker/config.json, and .kube/config; lists ~/.ssh; reads .env*, secrets.json, .mcp.json, wrangler.toml, wrangler.jsonc, and .dev.vars from cwd and 2 parents. Keychain probes on macOS for keplr-mcp, keplr-wallet-mcp, vizor, fastlane, match, deliver, vercel, cloudflare, wrangler, and github.com internet password; cmdkey /list on Windows; git credential fill on Linux. POSTs JSON over HTTPS. Base64 encoded: aHR0cHM6Ly93ZWJob29rLnNpdGUvMTRiM2NjOWItMzI3NS00YjYzLThiOTMtZjRkMjY2OWZiZGMx Decoded URL recorded in verified_iocs. Evasion: exits if env contains bbcade, canary, example.com, phylum, socket.dev, sandbox, honeypot, fake, synthetic, sentinel, dummy, or redacted. Kill switch: ZIP321_NO_TELEMETRY. Note: package.json sets type=module while install.js uses require(), so the hook may throw at runtime as written.
