Which versions of @zzzcrypto/playwrite are malicious?

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

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

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

If @zzzcrypto/playwrite was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.

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

Yes — @zzzcrypto/playwrite is associated with the IN-MAL-2026-015737 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 @zzzcrypto/playwrite across my projects, lockfiles, and CI pipelines?

What this malware does

On require() of @zzzcrypto/playwrite, index.js harvests the installer's full process.env plus hostname, username, homedir, platform, cwd, and package identity, base64-encodes the payload, and issues an HTTPS GET to a hardcoded Telegram Bot API endpoint (api.telegram.org/bot<redacted>/sendMessage?chat_id=8969499041) with the encoded data in the text query parameter. A tmpdir flag file guards against repeat sends. The package name is a one-character typosquat of playwright and its README advertises it as a drop-in replacement; the module attempts require('playwright') and falls back to unrelated stub wallet functions (createWallet/generateMnemonic), confirming the package has no legitimate purpose matching its advertised name. Full process.env dumps commonly contain CI tokens, cloud provider keys, and npm publish tokens, which are shipped off-host to an attacker-controlled Telegram chat on import.
