This is the 3rd MtGox account I've heard of that's been cleaned out in the last week. A new vulnerability, perhaps?
Adobe released an emergency patch today for a Flash vulnerability that "is being exploited in the wild" and could lead to malicious code running on users' computers.I am still waiting to hear about the first person who ever loses a single bitcoin stored on a paper wallet.
To be fair, a common use for a paper wallet is long term storage, so there is a lag between the use of paper wallets and the reporting of lost coins with them. The majority of paper wallets that have been created have probably never been redeemed. When people finally get around to redeeming them, they may find them lost, destroyed, stolen, or that the private keys were printed incorrectly in the first place.
Wish MtGox offered a way to lock withdrawals to a single address. This would solve so much.
2-factor authentication solves 99.9% of the issues with stolen mtgox accounts.
