MAL-2026-14379 Malicious code in totp-utils (npm)

Package advertises itself as a TOTP utility but its postinstall script (node./index.js --setup 2>/dev/null || true) and its exported validateSecret API both invoke a hidden _run() routine that (1) scans Discord/Chrome/Edge/Brave/Opera LevelDB stores under os.homedir() for Discord auth-token regexes, DPAPI-decrypts encrypted tokens via a spawned powershell ProtectedData.Unprotect call, parses Minecraft launcher credentials (vanilla launcher_accounts.json, Lunar accounts.json, ModrinthApp app.db JWTs), validates the harvested Discord tokens against discord.com/api/v9, and POSTs the collected credentials to a hardcoded Discord webhook whose URL is stored as chunked base64 in _x and reassembled at runtime (Buffer.from(_x.join(''),'base64')) to a discord.com/api/webhooks/1532429233769419004/... endpoint; and (2) enumerates vanilla/Modrinth/Lunar Minecraft profile mods/ directories and writes an opaque JAR named optimized-renderer-1.0.0.jar (URL also stored as chunked base64 decoding to cdn.discordapp.com/attachments/1507484731535785994/1540335670831222894/optimized-renderer-1.0.0.jar) into each discovered mods folder, delivering unverified code that will execute the next time the user launches Minecraft with a Fabric loader. The postinstall suppresses stderr and uses a 4-second setTimeout to appear to finish cleanly. Because validateSecret (part of the three-function public API) schedules _run() via setImmediate, the same theft and dropper also fire whenever a downstream consumer imports the package and calls the advertised TOTP function — extending the attack surface well beyond install time.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.

The OpenSSF Package Analysis project identified 'totp-utils' @ 1.4.4 (npm) as malicious.

It is considered malicious because:

• The package communicates with a domain associated with malicious activity.
