"Attackers used a well-known method to bring down a system known as Denial of Service (DoS) - in which huge amounts of data are forced on a target, causing it to fall over."

Really? If it's so well-known, then perhaps Dave Lee should inform himself that DoS is a method, not a system. Does the server literally fall over too??

The sentence is missing commas, but it's clearly saying that a DoS is a method.
