# MAL-2026-12794: Malicious code in karapace-docs (npm)

## What is MAL-2026-12794?

MAL-2026-12794 is a malicious package in karapace-docs, published on 5 Aug 2026. 

### Official description

The npm package's preinstall hook runs index.js at install time, which collects the installer's hostname, username, home directory, DNS server list, and the contents of /etc/passwd and /etc/hosts, then POSTs a JSON payload over HTTPS to a hardcoded Burp Collaborator subdomain n6usddpvkn7jcauar9va0xvleck48uwj.oastify.com. The package name mimics a documentation package for karapace (a Kafka registry project), consistent with a dependency-confusion / typosquat recon payload. Installer host identity and local system file contents leave the machine to an attacker-controlled OAST endpoint on `npm install` with no 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-2026-12794?

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