Which versions of @zzzgenesis00/playwrite are malicious?

The following npm versions of @zzzgenesis00/playwrite are flagged malicious: 1.48.0. Treat any of these as compromised.

How do I remediate @zzzgenesis00/playwrite if I installed it?

@zzzgenesis00/playwrite 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.

I already installed @zzzgenesis00/playwrite — how do I know if it already compromised me?

If @zzzgenesis00/playwrite 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.

Is @zzzgenesis00/playwrite part of a known attack campaign?

Yes — @zzzgenesis00/playwrite is associated with the IN-MAL-2026-011524 campaign. Packages in the same campaign often share infrastructure and payloads, so check whether any related packages are also in your dependency tree.

How do I find @zzzgenesis00/playwrite across my projects, lockfiles, and CI pipelines?

Scan your lockfiles (package-lock.json, pnpm-lock.yaml, yarn.lock, requirements.txt, poetry.lock, etc.) and build artifacts for @zzzgenesis00/playwrite (version 1.48.0). O3 Security's supply-chain scanner checks every dependency against known-malicious package intelligence at install time and in CI, flagging @zzzgenesis00/playwrite across your stack and pipelines.

What this malware does

The package @zzzgenesis00/playwrite is a typosquat of playwright. Its exported launch() returns empty stub methods, while postinstall.js (also loaded transitively via index.js) runs on npm install and require. It collects hostname, username, homedir, platform, cwd, node version, npm registry configuration and the output of npm whoami via execSync, and harvests credential-shaped environment variables including NPM_TOKEN, GITHUB_TOKEN, AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, AWS_SESSION_TOKEN, DOCKER_PASSWORD, GCLOUD_ACCESS_TOKEN and NPM_CONFIG. It enumerates ~/.ssh (id_rsa, id_ed25519, id_ecdsa and.pub files), reads ~/.npmrc and ~/.gitconfig, and scans Chrome, Chromium and Firefox profile directories for Cookies and Login Data. The collected data is JSON-POSTed over HTTPS to the hardcoded Serveo reverse-tunnel host 40f955f39128bd79-178-249-214-24.serveousercontent.com at path /collect, with a 2-second setTimeout delay and a try/catch wrapper commented to keep npm install silent on failure.
