Malicious package

Published to npm · OSV MAL-2026-6585

What to do

Remove stake-math from every project, lockfile and image that pulls it in. Treat any host that installed it as compromised: rotate the credentials, tokens and keys it could read, from a clean machine.

Description

The npm package 'stake-math' versions 3.5.2, 3.5.3, and 3.5.4 contains malicious code that executes arbitrary attacker-controlled commands during installation. The package's postinstall script fetches and runs code from an untrusted external source unrelated to the legitimate publisher, leading to full system compromise. The package also impersonates another brand to deceive users. Systems with this package installed should be considered fully compromised, and secrets must be rotated immediately.

Impact

Installing affected versions of 'stake-math' results in arbitrary code execution with the installer's privileges, effectively giving attackers full control over the compromised system. This can lead to theft of secrets, keys, and other sensitive data. The compromise is severe enough that all secrets on the affected machine should be considered exposed and rotated immediately. Removal of the package alone does not guarantee eradication of all malicious artifacts or backdoors.

Defensive guidance

Users should immediately remove versions 3.5.2, 3.5.3, and 3.5.4 of the 'stake-math' package from their systems. Because the package executes attacker-controlled code during installation, any system with these versions installed should be treated as fully compromised. All secrets and keys stored on the affected system must be rotated from a separate, trusted environment. Monitor for and investigate any suspicious activity related to this package. Avoid installing packages from untrusted sources and verify package authenticity before installation.

Summary

The 'stake-math' npm package in versions 3.5.2, 3.5.3, and 3.5.4 includes a postinstall hook that downloads a JSON configuration from a hardcoded, non-publisher-controlled domain (https://www.log-prettier.store), retrieves a tarball URL, downloads and extracts it, runs a nested npm install, and executes a JavaScript file ('peer-math.js') within the installer's Node.js process. This process allows arbitrary code execution controlled by an attacker. The package exhibits identity divergence, with mismatched package name and README branding, and a homepage pointing to the malicious domain, indicating brand impersonation to lure victims. Installing this package version results in full compromise of the host machine.
