Now THAT is a hacker in my book. Using timing to exploit running code is a lost art form these days. Having the know how to pull a trick like that off is even rarer. Time was when it was the lion's share of the lore leading up to the keys to the kingdom in the days of phone phreaking. It wasn't just the tones. It was also getting the timing exactly right in order to get in and not trip warning bells or let the dogs off the leash. Small wonder so many old school hackers (in the old meaning of the word) were also usually pretty decent musicians whenever they were away from their keyboard. It didn't mean a thing unless you could swing.
I don't know
about any of this personally
mind you. I've just "been told."
