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 binary reads credential-grade environment variables including AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, AWS_SESSION_TOKEN, GITHUB_TOKEN, NPM_TOKEN, NODE_AUTH_TOKEN, SYSTEM_ACCESSTOKEN, ACTIONS_RUNTIME_TOKEN, and ACTIONS_ID_TOKEN_REQUEST_TOKEN, along with hostname, uid, and current working directory, and POSTs them as JSON to the hardcoded host `oob.s4yhii.com` via a raw socket (`POST /native HTTP/1.0`). The native code also invokes `fork`/`setsid` to detach from the parent process. The package is published as `@brick-v2/core` at version `999.0.1` with a trivial JS wrapper, a generic `core module` description, and `UNLICENSED` — a shape consistent with a dependency-confusion payload targeting a private `@brick-v2` scope so that npm resolution prefers this public version over an internal package.\n","state":0,"publishedAt":"2026-10-09T00:00:00+00:00","modifiedAt":"2026-10-12T05:30:06.9903544+00:00","affected":[{"ecosystem":"npm","name":"@brick-v2/core","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"}]}],"versions":["999.0.2","999.0.1"],"rawVersionEvidence":null}],"metrics":[],"references":["https://www.npmjs.com/package/@brick-v2/core/v/999.0.2","https://www.npmjs.com/package/@brick-v2/core/v/999.0.1","https://www.npmjs.com/package/@brick-v2/core"],"sourceUrl":"https://osv.dev/vulnerability/MAL-2026-17715","license":"OSV · upstream source license applies","key":"osv:MAL-2026-17715","identifiers":["MAL-2026-17715"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
