The number of "double spends" (most of which I believe is mutated transactions) for the last 24 hours:
2014-02-11 16960
(will edit OP to reflect this)

It is slightly lower than I anticipated, as it was already above 16k 9 hours before the CET day ended (24 hours). Maybe the attack subsided, or someone is having a break.

this is probably related to the current malleability attack on the bitcoin network (25% of transactions were affected today). it has nothing to do with your theft.

In addition to the above jgarzik is quoted on reddit to have said that one home PC could have done this. One home PC can screw up 25% of transactions!

Hold on. Are there actually any reports of something being screwed, apart from couple of exchanges who stopped withdrawals as a precaution measure?

It depends on what you mean by "screwed up". The attacker can't change the inputs or outputs or fees, however they can change the tx hash of unconfirmed txs. There were over 16,000 tx "mutated" in the last 24 hours. I am sure they weren't all withdraws from exchanges. It would appear the attackers are simply mutating in mass all transactions they are able to and broadcasting the mutated version into the network. If the mutated version of the tx is the one which gets confirmed it can have consequences for any user.

So, don't deliver until the transaction to you is confirmed, is that....news?

Obviously you didn't read the post or link. I said nothing about delivering goods before confirmed.

I am not saying you have said anything wrong, I was referring to the panic. And I don't think such consequences can be considered "screwed up", as an end user I would probably not even notice anything other than a slow-up of the network if I don't pay attention.

You wouldn't notice a transaction you made (or someone made to you) that never confirms due to no fault of your own. By never, I mean never. Not in an hour, or a day, or a year.

Most people would and they probably would consider that "screwed up".

Well, I don't know about you, but when I actually want to see if my tx gets confirmed, I always search for the address and check if there is a new transaction with the correct amount, probably it's just me though...

Once again you might want to read the link. I am not talking about it being confirmed under a new tx id. I am talking about it NEVER confirming because it now has become invalid due to the inputs being invalid.

Well, you said the mutated one gets confirmed, can I find the one or not? Thanks.

EDIT: Okay, I read your OP, I was awfully unaware of the way the reference client works as I have never actually used it, thanks.
