Do you really think this is the only one? I would bet EVERY chip, firmware and software in our computers if full of these backdoors. The backdoors are patched but new ones are always found. Just assume someone is watching or listening to you when you use your computer.
Sorry, but I seriously doubt that EVERY chip and piece of software is that compromised. If nothing else, the ‘nix coders would have found it and developed patches to bypass the security ‘features’ as quickly as possible.
