Early versions resolve \u003chostname\u003e.\u003ctag\u003e.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/\u003cplatform\u003e-\u003carch\u003e/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\nThe package's main entry `index.js` loads a prebuilt native binary at `prebuilds/\u003cplatform\u003e-\u003carch\u003e/metrics.node` inside a top-level try/catch, executing native code within the Node process as soon as the module is required. 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.","ecosystems":["npm"],"exploits":{"exploitdb":null,"first_seen":null,"github_poc":null,"max_poc_stars":null,"metasploit":null,"nuclei":null,"refs":[],"tier":null},"has_fix":false,"headline":"Malicious code in @brick-v2/core (npm)","id":"MAL-2026-17715","indexable":true,"kev":null,"kind":"malicious","links":{"ecosystem":"npm","product":null,"products":[],"type":null,"year":"2026"},"n_packages":1,"n_references":null,"packages":[{"ecosystem":"npm","fixed":[],"introduced":["0"],"last_affected":[],"package":"@brick-v2/core","purl":"pkg:npm/%40brick-v2/core","source":"MAL-2026-17715"}],"products":null,"published":"2026-10-09","related":[],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"OpenSSF Malicious Packages","prefix":"MAL"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":null,"updated":null,"vendors":null},"summary":null,"url":"https://insights.sbomify.com/MAL-2026-17715/"}
