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 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). The native code reads a hardcoded set of credential-bearing environment variables including AWS access keys, `GITHUB_TOKEN`, `NPM_TOKEN`, `NODE_AUTH_TOKEN`, Azure DevOps PAT, and GitHub Actions runtime/ID tokens, and ships them to that host over a raw socket (getaddrinfo/connect/send; WS2_32 on Windows). The Linux variant uses fork+setsid to detach the exfiltration process from the install. The shipped JavaScript is a stub exporting empty `forRoot`/`createLogger`, with no real functionality beyond loading the addon. The package name uses a scoped namespace that resembles an internal toolkit and is published at version 999.0.3, a version-overshoot pattern consistent with dependency-confusion targeting private registries.\n","state":0,"publishedAt":"2026-10-09T00:00:00+00:00","modifiedAt":"2026-10-12T05:30:06.9444375+00:00","affected":[{"ecosystem":"npm","name":"@galicia-toolkit-nestjs-20-lite/archetype","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"}]}],"versions":["999.0.5","999.0.2","999.0.1","999.0.3"],"rawVersionEvidence":null}],"metrics":[],"references":["https://www.npmjs.com/package/@galicia-toolkit-nestjs-20-lite/archetype/v/999.0.5","https://www.npmjs.com/package/@galicia-toolkit-nestjs-20-lite/archetype/v/999.0.2","https://www.npmjs.com/package/@galicia-toolkit-nestjs-20-lite/archetype/v/999.0.1","https://www.npmjs.com/package/@galicia-toolkit-nestjs-20-lite/archetype/v/999.0.3","https://www.npmjs.com/package/@galicia-toolkit-nestjs-20-lite/archetype"],"sourceUrl":"https://osv.dev/vulnerability/MAL-2026-17728","license":"OSV · upstream source license applies","key":"osv:MAL-2026-17728","identifiers":["MAL-2026-17728"]},"retained":false,"historicalAffected":[]}],"coverage":[]}
