## What is MAL-2026-16362?

MAL-2026-16362 is a malicious package in @uh-platform/webcard, published on 21 Sep 2026. 

### Official description

@uh-platform/webcard@99.0.0 declares a preinstall hook that runs index.js, which shells out to curl against a unique Burp Collaborator subdomain at http://pa33pg1od9cr4ffnrzec8864jvpmdd12.oastify.com/. This fires unconditionally on npm install and confirms code execution and DNS/HTTP callback from the installer's host to an attacker-controlled out-of-band collector. The package version is 99.0.0 under an org scope with a self-referential dependency on @uh-platform/webcard@1.0.2 and a redacted SDK description, matching the canonical dependency-confusion shape aimed at hijacking resolution of an internal scoped package name.

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-2026-16362?

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