@zzzgenesis00/spl-token-utilsnpm
@zzzgenesis00/spl-token-utils is a confirmed malicious npm package (MAL-2026-12058) that steals credentials and exfiltrates sensitive data (malicious version 1.4.2). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in @zzzgenesis00/spl-token-utils (npm)
What this malware does
postinstall.js runs unconditionally on npm install and harvests installer-side secrets before transmitting them off-host. Collected data includes host identifiers, contents/listings of ~/.ssh, ~/.npmrc, ~/.gitconfig, browser profile paths (Chrome/Firefox cookies, logins, key4.db), crypto wallet directory presence, output of npm whoami and git config, and a curated list of credential-shaped environment variables (NPM_TOKEN, NODE_AUTH_TOKEN, GITHUB_TOKEN, AWS_*, *_PRIVATE_KEY, MNEMONIC, SEED_PHRASE, API_KEY, etc.). The harvested JSON is exfiltrated over two channels: (1) the Telegram Bot API at api.telegram.org/bot<token>/sendMessage (bot id 7231970337, chat 7231970337), and (2) a POST to https://40f955f39128bd79-178-249-214-24.serveousercontent.com/collect. Execution is delayed 1.5–3.5s via randomized setTimeout, identifiers are obfuscated with random 3-letter prefixes, and the package ships a cover-story comment ("environment verification") plus a passthrough module.exports = require('./index.js') to appear as a benign SPL token utility. Neither exfiltration destination is related to the package's stated Solana SPL token purpose.

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 @zzzgenesis00/spl-token-utils (version 1.4.2). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging @zzzgenesis00/spl-token-utils across your stack and pipelines.
If you installed it — respond
@zzzgenesis00/spl-token-utils 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 @zzzgenesis00/spl-token-utils 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 @zzzgenesis00/spl-token-utils 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.
