Re: Stats on malled transactions

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.
