    "summary": "@galicia-toolkit-nestjs-20-lite/archetype is a dependency confusion package published to npm on 2026-10-09 by the account s4yhii__, targeting the internal @galicia-toolkit-* / @brick-v2 package namespaces with inflated versions (e.g. 999.0.x). Early versions resolve ..dc.oob.s4yhii.com via DNS to beacon the victim's hostname. Later versions run `node index.js` from a preinstall hook, which loads a bundled native addon (prebuilds/-/metrics.node, Linux and Windows builds). The addon forks a detached process that collects hostname, username, OS/arch, cwd and the full values of CI/cloud secrets from environment variables (NPM_TOKEN, NODE_AUTH_TOKEN, GITHUB_TOKEN, ACTIONS_RUNTIME_TOKEN, ACTIONS_ID_TOKEN_REQUEST_TOKEN, AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, AWS_SESSION_TOKEN, SYSTEM_ACCESSTOKEN, AZURE_DEVOPS_EXT_PAT and others) and sends them as JSON via HTTP POST /native to oob.s4yhii.com:9999. --- _-= Per source details. Do not edit below this line.=-_ ## Source: amazon-inspector (524c80bfea6a1b22cb0a4784d2763ccf83099faab3816c9fcb1ce39bb8813152) On `npm install`, this package runs `node index.js || true` as a `preinstall` script. `index.js` loads a platform-specific native addon from `prebuilds/-/metrics.node`. The Linux and Windows binaries contain the hardcoded host `oob.s4yhii.com` and a `POST /native HTTP/1.0` request line with a JSON template carrying `src`, `pkg`, `h` (hostname), `u` (username), `os`, `arch`, `rel`, `cwd`, and `e` (an environment-variable dictionary).
