Source: amazon-inspector (2242b683433d5fe37b3997185d251799a4606a456e516da08586775d11f0cb7e)

@gsas/gsas-sdk@999.9.15 is a high-version public-registry squat targeting an internal @gsas/gsas-sdk name. package.json declares preinstall: node index.js, and index.js runs on install to collect the installer's hostname, username, home directory, cwd, local/public/resolver IPs, npm registry URL, CI platform with repo/actor/run/workflow/runner, AWS region, git email domain, and the consuming project's name/author/repo/homepage. It also spawns gh api user --jq.login, npm whoami, and git config user.email to capture the developer's authenticated GitHub login, npm login, and email. The collected JSON is hex-encoded, split into 60-character chunks emitted as DNS subdomain queries under da51rv0hb2uc72tg4gvgdepinjcallbk1.oast.fun, and additionally POSTed over HTTP and HTTPS to the same host (path /poc/<uuid>). Public-IP discovery calls out to api.ipify.org, icanhazip.com, and ifconfig.me. Comments in the file describe the multi-channel design as intended to survive corporate egress filtering. An AUTHORISED SECURITY RESEARCH self-label appears in the source but does not correspond to installer consent.
