The UK's GCHQ cyber arm has moved into commercial hardware for the first time, producing a device aimed at blocking cyberattacks delivered through monitor cables. Details remain scarce, but the fact that a signals intelligence agency is now selling protective gadgets to organisations signals just how seriously physical display infrastructure is being taken as an attack surface.

The reason is Beijing itself, which is actively discouraging Chinese companies from buying American chips in order to accelerate its own domestic semiconductor industry. It's a striking case of a country voluntarily blocking imports to build strategic independence.
