Part of a dependency confusion attack campaign targeting the @cloudplatform-single-spa and @mlspace npm scopes. The attacker (npm user mr.4nd3r50n) published 139 scoped packages at the inflated version 99.99.99, which resolves ahead of any private registry version via npm's default version resolution, silently hijacking installs of internal packages.

This specific package carries no active postinstall payload and its description claims "BugBounty testing". However, it squats a legitimate internal package namespace at an inflated version as part of the broader campaign.
