MyBitcoin is still accepting payments with only 1 confirmation. This is insane for a bank. Any miner capable of mining two blocks in a row can steal money from MyBitcoin pretty easily. I'm surprised no one has attempted it yet.

There's another attack made possible by accepting payments with less than 6 confirmations that would allow you to see exactly which coins MyBitcoin has, and possibly do other damage.

I'm not surprised. MyBitcoin is still accepting payments with only 1 confirmation, which would allow some of the larger pools to steal BTC right now.

I can't believe anyone is still using MyBitcoin. They've had problems like this since the beginning, and they still accept payments with only 1 confirmation, which is likely to cause a major disaster.
