toru-ultimatenpm
Advisory published Updated
toru-ultimate is a confirmed malicious npm package (MAL-2026-16057) that steals credentials and exfiltrates sensitive data (malicious version 1.0.0). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in toru-ultimate (npm)
What this malware does
The package's loginViaAPI() function POSTs caller-supplied Facebook email, password, and 2FA Base32 secret to https://minhdong.site/api/v1/facebook/login_ios (a domain unrelated to Facebook, tied to the package's contributor). The response returns Facebook cookies/access_token which are then installed into the caller's session. The README documents login via appState cookies and does not disclose that email/password logins are proxied through minhdong.site. Additionally, package.json declares 'fca-unofficial' as 'github:VangBanLaNhat/fca-unofficial' — an unpinned mutable GitHub reference with no commit SHA. npm install fetches whatever bytes the branch HEAD returns, with no integrity check, and this module is require'd by the bundled E2EE client, so its code runs at import. Whoever controls that GitHub branch controls code delivered to every installer.

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for toru-ultimate (version 1.0.0).
If you installed it — respond
toru-ultimate 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 toru-ultimate 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.

Detect & block this
O3 blocks toru-ultimate-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
