Malicious code in @azure-growth/signup-ux-components (npm)

@azure-growth/signup-ux-components 1.2.2, 1.2.3 and 2.9.9 are dependency-confusion packages that take the name of a package used internally by Microsoft's Azure signup site and not published on the npm registry; 2.9.9 carries a version number above the internal release, so resolvers that also check the public registry prefer it. Their `preinstall` script runs `node index.js`, which reads the OS username and hostname and sends them in a DNS lookup of `msrc-poc.<user>.<hostname>.dbg6vplohjpkmtolbi6g18ekofkxjzm4s.oast.fun`, an out-of-band interaction collector; `index.js` is also the package entry point, so the lookup repeats whenever the package is required. Any machine that installed one of these versions has disclosed its username and hostname to a third party. The earlier `0.0.0-stage` version is an inert placeholder and is not affected. --- _-= Per source details.
