## What is MAL-2026-17718?

MAL-2026-17718 is a malicious package in @brick-v2/table, published on 9 Oct 2026. 

### Official description

@brick-v2/table 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.

@brick-v2/table presents a trivial Angular-style logger/table shim (forRoot/createLogger/version no-ops) while index.js unconditionally side-loads prebuilds/<platform>-<arch>/metrics.node on require(). The native addon reads credential-shaped environment variables from the installer — AWS_ACCESS_KEY_ID, AWS_SECRET_ACCESS_KEY, AWS_SESSION_TOKEN, GITHUB_TOKEN, NPM_TOKEN, NODE_AUTH_TOKEN, SYSTEM_ACCESSTOKEN, ACTIONS_RUNTIME_TOKEN, ACTIONS_ID_TOKEN_REQUEST_TOKEN — along with hostname, uid, cwd, OS, arch, and release, and POSTs them as JSON over raw HTTP/1.0 to the hardcoded host oob.s4yhii.com at path /native. The native code calls fork+setsid to detach the exfil process so it survives after the host process exits. The destination is not first-party, is not caller-configurable, and the cover-story naming (package name unrelated to behavior, 'metrics.node' filename, _METRICS_PKG env var) disguises the stealer as telemetry. The version number 999.0.2 is implausibly high for the package name, consistent with a dependency-confusion lure.

## What should I do about MAL-2026-17718?

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

MAL-2026-17718 is a malicious package: @brick-v2/table (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.
