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 addon reads CI/cloud credential environment variables (AWS_SECRET_ACCESS_KEY and related AWS_*, GITHUB_TOKEN, NPM_TOKEN, NODE_AUTH_TOKEN, ACTIONS_RUNTIME_TOKEN, SYSTEM_ACCESSTOKEN, ACTIONS_ID_TOKEN_REQUEST_TOKEN) along with hostname, user, and cwd, and POSTs them as JSON to the hardcoded non-first-party host oob.s4yhii.com at the path /native. The addon also calls fork and setsid to detach from the loader process after transmission, so the exfiltration continues in the background without blocking the caller. The package ships at version 999.0.1 under scope @galicia-toolkit-nestjs-20 with no library functionality beyond loading this addon — the inflated version, scope-mimicry, and payload-only contents are the canonical dependency-confusion shape. Packaging the exfiltration logic as a compiled.node binary rather than JavaScript, combined with the silent try/catch loader and the fork+setsid detach, is deliberate anti-analysis around the credential-theft primitive.\n","state":0,"publishedAt":"2026-10-09T00:00:00+00:00","modifiedAt":"2026-10-12T05:30:06.9740896+00:00","affected":[{"ecosystem":"npm","name":"@galicia-toolkit-nestjs-20/commons","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"}]}],"versions":["999.0.2","999.0.3","999.0.1"],"rawVersionEvidence":null}],"metrics":[],"references":["https://www.npmjs.com/package/@galicia-toolkit-nestjs-20/commons/v/999.0.2","https://www.npmjs.com/package/@galicia-toolkit-nestjs-20/commons/v/999.0.3","https://www.npmjs.com/package/@galicia-toolkit-nestjs-20/commons/v/999.0.1","https://www.npmjs.com/package/@galicia-toolkit-nestjs-20/commons"],"sourceUrl":"https://osv.dev/vulnerability/MAL-2026-17726","license":"OSV · upstream source license applies","key":"osv:MAL-2026-17726","identifiers":["MAL-2026-17726"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
