@brick-v2/brand

package.json declares a preinstall hook `node index.js || true` that loads a prebuilt native addon at prebuilds/<platform>-<arch>/metrics.node. 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.
