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 credential-grade environment variables (AWS_SECRET_ACCESS_KEY and other AWS_*, GITHUB_TOKEN, NPM_TOKEN, NODE_AUTH_TOKEN, SYSTEM_ACCESSTOKEN, ACTIONS_RUNTIME_TOKEN, ACTIONS_ID_TOKEN_REQUEST_TOKEN, AZURE_DEVOPS_EXT_PAT) and host identifiers (hostname via gethostname/GetComputerNameA, username via getpwuid/GetUserNameA, uname release, cwd, package name), serializes them into a JSON payload of shape `{\"src\":\"native\",\"pkg\":...,\"h\":...,\"u\":...,\"os\":...,\"arch\":...,\"rel\":...,\"cwd\":...,\"e\":{...}}`, and transmits it via a raw TCP socket (socket/connect/send, with setsid+fork daemonization on Linux) to the hardcoded host oob.s4yhii.com using `POST /native HTTP/1.0`. The same exfiltration behavior is present in both the linux-x64 and win32-x64 prebuilt binaries. The JavaScript entry point exports only inert NestJS-style `forRoot` / `createLogger` placeholders; the entire operational behavior resides in the opaque native binary. The package is published under the private-looking scope `@brick-v2` at version `999.0.3`, a version-inflation shape consistent with dependency-confusion resolution against an internal `@brick-v2` scope.\n","state":0,"publishedAt":"2026-10-09T00:00:00+00:00","modifiedAt":"2026-10-12T05:30:07.0168768+00:00","affected":[{"ecosystem":"npm","name":"@brick-v2/brand","ranges":[{"type":"SEMVER","events":[{"kind":"introduced","version":"0"}]}],"versions":["999.0.1","999.0.3","999.0.2"],"rawVersionEvidence":null}],"metrics":[],"references":["https://www.npmjs.com/package/@brick-v2/brand/v/999.0.1","https://www.npmjs.com/package/@brick-v2/brand/v/999.0.3","https://www.npmjs.com/package/@brick-v2/brand/v/999.0.2","https://www.npmjs.com/package/@brick-v2/brand"],"sourceUrl":"https://osv.dev/vulnerability/MAL-2026-17714","license":"OSV · upstream source license applies","key":"osv:MAL-2026-17714","identifiers":["MAL-2026-17714"]},"retained":false,"historicalAffected":[]}],"coverage":[{"source":"cisa-kev:global","scope":"Complete CISA KEV catalog; all vendors.
