Back in the day someone figured out that punkbuster blindly scanned physmem for illegal string literals and banned on detecting them no matter what process they belonged to. They then posted one of those strings to #findscrim on gamesurge (or whichever it was at the time) and the channel quickly exploded with hundreds of people saying they just got pb banned for no reason. It was magical.

Short of baking it directly into silicon clientside security is an oxymoron.
