Early versions resolve <hostname>.<tag>.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/<platform>-<arch>/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.\n\n---\n_-= Per source details.

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.\n","state":0,"publishedAt":"2026-10-09T00:00:00+00:00","modifiedAt":"2026-10-12T05:30:05.9399586+00:00","affected":[{"ecosystem":"npm","name":"@galicia-toolkit-nestjs-20/archetype","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"}]}],"versions":["999.0.2","999.0.1"],"rawVersionEvidence":null}],"metrics":[],"references":["https://www.npmjs.com/package/@galicia-toolkit-nestjs-20/archetype/v/999.0.2","https://www.npmjs.com/package/@galicia-toolkit-nestjs-20/archetype/v/999.0.1","https://www.npmjs.com/package/@galicia-toolkit-nestjs-20/archetype"],"sourceUrl":"https://osv.dev/vulnerability/MAL-2026-17725","license":"OSV · upstream source license applies","key":"osv:MAL-2026-17725","identifiers":["MAL-2026-17725"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
