Which versions of secretkey2fa are malicious?

The following npm versions of secretkey2fa are flagged malicious: 1.0.1. Treat any of these as compromised.

How do I remediate secretkey2fa if I installed it?

secretkey2fa 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 secretkey2fa — how do I know if it already compromised me?

If secretkey2fa 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 secretkey2fa part of a known attack campaign?

Yes — secretkey2fa is associated with the IN-MAL-2026-019142 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 secretkey2fa across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for secretkey2fa (version 1.0.1).

What this malware does

Package is advertised as a lightweight TOTP/HOTP library, but its package.json declares a postinstall hook (node lib/core.js) that runs a Windows credential stealer on install. The payload enumerates Windows Credential Manager entries matching MCL|*|Xal* via inline P/Invoke PowerShell (CredEnumerate/CredRead), reads launcher account JSON files under %APPDATA%.minecraft\launcher_accounts*.json, extracts Microsoft Account refresh tokens (regex M.C...) and access tokens, and exchanges them at login.live.com/oauth20_token.srf, Xbox Live, and minecraftservices endpoints to obtain session identifiers. It also builds a Chromium DPAPI decryption chain (PowerShell [System.Security.Cryptography.ProtectedData]::Unprotect against os_crypt.encrypted_key from Chrome's Local State, plus an AES-256-GCM decipher) to decrypt browser cookie/credential blobs. Harvested data is posted as JSON and multipart file uploads to a hardcoded Discord webhook whose URL is concealed as an XOR-0x3F byte array (_W) decoded at runtime along with other sensitive strings (powershell, child_process, ProtectedData, discord user-agent). An _env() gate short-circuits on CI, during npm audit/npm pack, when %APPDATA%/USERPROFILE/USERNAME/COMPUTERNAME are missing, or when ~/Documents is absent, so the payload only fires on real Windows developer hosts. The 2FA description is a cover story.
