## What is MAL-2026-13422?

MAL-2026-13422 is a malicious package in beautiful-ui-monitoring, published on 6 Aug 2026. 

### Official description

beautiful-ui-monitoring@1.0.8 advertises itself as a UI package (description 'creates a beautiful ui design', keywords c/gcc/native) but ships no UI code. Its postinstall script invokes `gcc -shared -fPIC -o /tmp/monitoring.so src/monitoring.c`, compiling a shipped C source into a shared library at a world-writable path. The compiled library declares a `__attribute__((constructor))` that, on load, unlinks every `*.so` file under `/tmp` and writes the current uid/gid to `/tmp/monitoring.log`. The tarball also ships a `test.js` that loads the library via `LD_PRELOAD=/tmp/monitoring.so` and a co-shipped native test-loader that `dlopen`s the same path, demonstrating the intended trigger. The package.json author field is empty and no shipped file implements the advertised UI purpose. Installing the package plants a destructive native artifact in a shared, world-writable location under a misleading package description.

## What should I do about MAL-2026-13422?
