Malicious code in @uh-platform/nadaver2 (npm)

Details

**Severity:** Critical

**Affected versions:** `= 102.0.0`

## Source: amazon-inspector (c35cffdc174427ac57ea3c5e8ac02ec41159f8f25ffe1ef152e0437e5e533458)
The package's package.json declares a preinstall lifecycle hook that runs `node index.js`. index.js invokes child_process.exec on a curl command whose URL embeds `$(hostname)` and `$(whoami)` as DNS subdomains of `nadaver.pa33pg1od9cr4ffnrzec8864jvpmdd12.oastify.com`, a Burp Collaborator (OAST) endpoint. On `npm install`, the installer's hostname and OS username are transmitted to that attacker-controlled collaborator host via DNS and HTTP. The `@uh-platform` scope and the name shape are consistent with a dependency-confusion probe. There is no legitimate SDK, build, or install functionality in the package.
