## What is MAL-2026-17714?

MAL-2026-17714 is a malicious package in @brick-v2/brand, published on 9 Oct 2026. 

### Official description

@brick-v2/brand is a dependency confusion package published to npm on 2026-10-09 by the account s4yhii__, targeting the internal @galicia-toolkit-* / @brick-v2 package namespaces with inflated versions (e.g. 999.0.x). 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.

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.

## What should I do about MAL-2026-17714?

Remove the package from your dependencies and lockfiles, then rotate any secrets on machines where it was installed.

## Fix prompt for AI coding agents

```text
MAL-2026-17714 is a malicious package: @brick-v2/brand (npm). Every version was published to cause harm.

Task:
1. Search this repository's dependency manifests and lockfiles for the package, including transitive dependencies.
2. If it is present, remove it, regenerate the lockfile with the project's package manager, and replace whatever it was used for.
3. List any CI runners, developer machines or containers that installed it, so their secrets can be rotated.
4. If the package is not used anywhere, say so and change nothing.
