This is so full of poop as to be insulting. Their security breach has nothing to do with operating systems, and anyone that knows security knows this is an outright lie.
What part of "A root cause of the security breach: a Windows vulnerability in the retailer’s main computer network" DO YOU FAIL TO UNDERSTAND? That was the second sentence of the lede. It was published in the Wall Street Journal. It was asserted by the forensic digital data examiners of the breach.
You can scream and shout all you want that it's an "outright lie," CodeToad, but that is what was found: The breach was made through a Windows vulnerability on Home Depot's main computer network. . .
