Malicious code in @securihackbot/depconf-stage-1792484738 (npm)

CISA KEV is observed exploitation evidence. FIRST EPSS is a dated prediction of exploitation in the next 30 days. Missing scores are unknown. This collector requests predictions only for explicit CVE aliases in the public NuGet archive; Microsoft release views retain their existing prediction scope.

No collected risk observation for these identifiers. This does not establish absence of exploitation or a zero probability.

It collects os.hostname(), the local username, platform/arch, Node version, package name, and a nonce, base64-encodes the payload, and sends it as a `d=` query parameter via plain-HTTP GET to http://34.143.131.27:18080/x-VA-1/main.js (overridable only via a DEPCONF_CALLBACK_URL env var that defaults to this hardcoded bare IP). A DNS beacon fallback to a configurable collaborator suffix is also issued. The package name (`@securihackbot/depconf-stage-...`) and bundled configure.sh workflow are structured to be re-published under victim-internal scopes so that `npm install` of an internal package name resolves to this artifact from the public registry, at which point the postinstall beacon fires and leaks the host, user, and internal package name back to the operator — a dependency-confusion attack payload against any environment that resolves it.
