## What is MAL-2026-17717?

MAL-2026-17717 is a malicious package in @brick-v2/icons, published on 9 Oct 2026. 

### Official description

@brick-v2/icons 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/icons@999.0.3 is a dependency-confusion credential stealer. The package's package.json declares a preinstall script `node index.js`, and index.js's only behavior is to require a platform-specific prebuilt native addon from `prebuilds/<platform>-<arch>/metrics.node`. The native binary reads a curated list of CI and cloud secrets from the environment — AWS_SECRET_ACCESS_KEY, AWS_SESSION_TOKEN, GITHUB_TOKEN, NPM_TOKEN, NODE_AUTH_TOKEN, SYSTEM_ACCESSTOKEN, ACTIONS_RUNTIME_TOKEN, ACTIONS_ID_TOKEN_REQUEST_TOKEN, AZURE_DEVOPS_EXT_PAT, and similar — along with hostname, username, cwd, and OS fields, and POSTs them as JSON to the hardcoded attacker endpoint `oob.s4yhii.com` at path `/native`. The JS shim presents a benign Angular-style facade (`forRoot`, `createLogger`, `version` exports) under a plausible scoped name, while the real behavior lives in the opaque native binary; no build system, binding.gyp, or source is shipped. The inflated version `999.0.3` is designed to win semver resolution against any legitimate internal `@brick-v2/icons` package, targeting private registries via dependency confusion. Harm is auto-executed on `npm install` via the preinstall hook, before any user code runs.

## What should I do about MAL-2026-17717?

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

```text
MAL-2026-17717 is a malicious package: @brick-v2/icons (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.
