We've had a careful eye on the multiple Google AdWords accounts that have been hacked, and this forum representation is hardly all of the accounts that really do get attacked. But again, another hapless victim from WebmasterWorld has suffered the fate of being charged too much on Google AdWords and being locked out of his account.
Whatever these guys are doing, they're doing a good job because most of the people I've encountered who have been hacked are actually savvy users. Perhaps they don't have the best passwords (one only wonders), but it's hard to say.
However, this probably won't be the last reports of this. Google, in my opinion, needs to take safety precautions to prevent against this theft.
Maybe it's a good idea at this time to do a phone authorization (with a 4 digit code) for any substantial changes. That should prevent -- or at least mitigate -- the intrusions.
