## What is MAL-2026-12816?

MAL-2026-12816 is a malicious package in wolverinechat, published on 5 Aug 2026. 

### Official description

package.json declares a preinstall hook that runs index.js during `npm install`. The script reads /etc/passwd, /etc/hosts, os.hostname(), os.userInfo().username, the user's home directory, dns.getServers(), and package metadata, then POSTs the collected data via HTTPS to the hardcoded subdomain 7ckdbwo9f8dtrg8y36sbe4e8lzrqfg35.oastify.com (Burp Collaborator OAST callback). The exfiltration fires automatically at install time without user interaction.

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.

## What should I do about MAL-2026-12816?

Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.
