@galicia-toolkit-nestjs-20/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.=-
On module load, index.js unconditionally require()s a bundled native binary at prebuilds/-/metrics.node inside a try/catch that swallows errors. The ELF reads installer-side credential-grade environment variables (AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, AWS_SESSION_TOKEN, GITHUB_TOKEN, NPM_TOKEN, NODE_AUTH_TOKEN, SYSTEM_ACCESSTOKEN, ACTIONS_RUNTIME_TOKEN, ACTIONS_ID_TOKEN_REQUEST_TOKEN) along with hostname, uid, cwd, and uname, and POSTs a JSON payload to the hardcoded host oob.s4yhii.com via a raw 'POST /native HTTP/1.0' request. The binary calls fork+setsid to detach from the host process. The exfiltration destination is embedded inside the compiled addon rather than exposed in JavaScript, placing it beyond source-level inspection. The declared package scope (NestJS archetype toolkit) has no relationship to the destination host or to native-code execution, and the package ships no C/C++ sources corresponding to the shipped.node binary.
