## What is MAL-2026-14059?

MAL-2026-14059 is a malicious package in autbank-core, published on 15 Aug 2026. 

### Official description

On `npm install`, preinstall.js enumerates process.env for keys matching credential substrings (KEY, SECRET, TOKEN, PASSWORD, AWS, API, CREDENTIAL, AUTH, PRIVATE, NPM, GIT, GITHUB, GITLAB), reads the working directory's.env and package.json, runs `git remote -v`, and POSTs the collected data via https to a hardcoded webhook.site collector (https://webhook.site/34e76ae9-12e2-4fea-a33a-24f4e1ac5eb2). A companion postinstall.js labeled internally as 'backup exfil' POSTs os.hostname(), os.userInfo().username, and process.cwd() to the same endpoint. Both lifecycle hooks fire automatically on default install, with no relationship to any advertised package functionality.

## What should I do about MAL-2026-14059?

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