ksp-app@100.100.100

ksp-app@100.100.100 is a dependency-confusion-shaped npm package whose only payload is an opaque prebuilt Linux x64 native addon loaded at install time. package.json declares scripts.postinstall="node postinstall.js", which require()s prebuilds/linux-x64/addon.node. The tarball ships no C/C++ source, no binding.gyp, and no build tooling; index.js exports an empty object, so the entire package behavior is in the native binary. On load, the ELF addon reads the environment variables HOSTNAME, npm_package_name, and npm_config_registry and POSTs them over a raw socket to the hardcoded bare-IP endpoint http://64.181.165.115/dc (HTTP/1.0, Host: 64.181.165.115, format string h=%.40s&p=%.40s&u=%.20s&r=%.80s). The version string 100.100.100, inert JS stub, generic "Frontend utilities" description, and a beacon that reports the installer's configured npm registry are the signature of a dependency-confusion exfiltration package used to confirm installs inside victim environments and disclose internal registry URLs to a third party.
