Which versions of test__123q2 are malicious?

The following npm versions of test__123q2 are flagged malicious: 2.1.1. Treat any of these as compromised.

How do I remediate test__123q2 if I installed it?

test__123q2 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 test__123q2 — how do I know if it already compromised me?

If test__123q2 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 test__123q2 part of a known attack campaign?

Yes — test__123q2 is associated with the IN-MAL-2026-019306 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 test__123q2 across my projects, lockfiles, and CI pipelines?

Search your lockfiles and build artifacts for test__123q2 (version 2.1.1).

What this malware does

On npm install, the package's postinstall script sweeps the installer's home directory for crypto wallet and credential material and uploads it to an attacker-controlled Telegram bot. Targets include browser wallet extension profiles for MetaMask (nkbihfbeogaeaoehlefnkodbefgpgknn), Phantom, Trust, Coinbase, OKX, Rabby, Keplr, TronLink, Ronin, Solflare and Exodus; desktop wallets Exodus, Atomic, Electrum, Bitcoin Core (wallet.dat), Ledger Live, Trezor Suite, Wasabi, Sparrow, Guarda, Coinomi and Jaxx; and files under Desktop, Documents, Downloads and Projects matching mnemonic/seed/bip39/privatekey keywords plus.env,.npmrc,.netrc, id_rsa and ~/.aws material. Collected files are tarballed via the tar dependency and POSTed as a document to a hardcoded Telegram Bot API endpoint (https://api.telegram.org/bot<BOT_TOKEN>/sendDocument); the destination is not user-configurable. The package name and version carry no legitimate functionality that would justify this behavior.
