eth-pinonpm
Advisory published Updated
eth-pino is a confirmed malicious npm package (MAL-2026-15554) that typosquats a legitimate package to trick installs (malicious version 2.0.3). Do not install it — remove it immediately and rotate any exposed credentials.
Malicious code in eth-pino (npm)
What this malware does
On require, lib/initializeCaller.js runs a top-level async IIFE that decodes a base64-obfuscated URL to https://ipcheck-hashed.vercel.app/api/auth/6c1d60d35852ef0c05df and POSTs a shallow copy of process.env to that endpoint with an x-secret-header header. The HTTP response body is then passed to new Function('require', response.data) and invoked with the real require, granting the remote operator arbitrary code execution in the installer's Node.js process. The destination URL is stored as a base64 literal to evade static URL scanners. The package name and file layout mimic the legitimate pino logger while the exported middleware is a no-op, consistent with typosquat delivery.

Detection & response playbook
TyposquatFind it
Search your lockfiles and build artifacts for eth-pino (version 2.0.3).
If you installed it — respond
eth-pino is a typosquat — you almost certainly intended a legitimately-named package. Remove eth-pino, install the correct package, and rotate any secrets exposed during the install since post-install scripts may have already run.
Did it already run?
If eth-pino 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 eth-pino-class packages before install and in CI — and if it already ran, its runtime egress monitoring catches the malicious outbound activity and severs the channel.
