xapi-lib@88.2.3, 88.2.5, 90.2.1, and 90.3.1 describes itself as a package for getting IP location and metadata. Its preinstall hook runs on npm install and requests with the hardcoded Authorization value , which is the same in all four versions and differs from the value in each of the account's other packages. The npm account conx3993 published xapi-lib on 2026-10-15, one of 9 packages from that account between 2026-09-30 and 2026-10-15 whose preinstall hook calls realwbx.com. --- _-= Per source details. Do not edit below this line.=-_ ## Source: amazon-inspector (beac62be73c115f383ea095cc364879294d6c105817d3c0eb6bfb30ce7bcf46c) xapi-lib@88.2.3 declares in package.json, and index.js performs an unconditional top-level HTTPS GET to realwbx.com/ip.php (passing and a hardcoded Authorization header) on load. The call fires automatically during , sending the installer's source IP to a hardcoded non-publisher endpoint unrelated to any advertised functionality. The package itself is a one-file stub with no library content, so dependency resolution plus the preinstall beacon is the entire effect of installing it. The destination realwbx.com is not a publisher-aligned domain, the request is not caller-configurable, and no documentation discloses the outbound call.
