ts-toolkit-plusnpm
Advisory published Updated
ts-toolkit-plus is a confirmed malicious npm package (MAL-2026-12812) that steals credentials and exfiltrates sensitive data (malicious version 1.3.2). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in ts-toolkit-plus (npm)
What this malware does
The package's main entry defines a getPlugin() function that performs an HTTPS request to a hardcoded bare-IP endpoint at 31.97.137.157:45000/icons/112 and passes the response field data.credits to new Function('require','module',...,'Promise', data.credits), executing whatever the remote host returns with full Node.js context including require, process, Buffer, and globalThis. The destination URL is assembled from split protocol/separator/domain/path fragments and wrapped in benign 'icon/CDN' naming that hides the code-execution sink. The declared dependencies (@primno/dpapi for Windows DPAPI unwrap of browser-stored secrets, node-machine-id for host fingerprinting, better-sqlite3/sqlite3 for browser profile databases, socket.io-client) do not correspond to the advertised 'crypto checkout' purpose and pre-stage tooling a remote payload can invoke via the injected require() to harvest Windows browser credentials and cookies. Any consumer that require/imports this package and reaches the getPlugin path grants the remote operator arbitrary code execution on the installer's machine.
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.

Detection & response playbook
Credential / info stealerFind it
Search your lockfiles and build artifacts for ts-toolkit-plus (version 1.3.2).
If you installed it — respond
ts-toolkit-plus 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 ts-toolkit-plus 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 ts-toolkit-plus-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the credential exfiltration and severs the channel.
