Once a transaction has 6 confirmations, it is extremely unlikely that an attacker without at least 50% of the network's computation power would be able to reverse it.

While I lost 2 BTC with 209 other investors on BTCJam to a scammer it is so refreshing to see a refreshing act. Smiley

I'm impressed. With all the new Bitcoin companies sure to come, perhaps being a freelance cryptosecurity hacker might be in your line of work?

What about this claim, was it confirmed? It does not seem to have been picked up by @johoe.

Here is one BCI user who claims to have lost 99 BTC which were not moved to the Good Samaritan's address:

http://www.reddit.com/r/Bitcoin/comments/2oo72b/victim_100_bitcoins_stolen_from_blockchaininfo/

The destination address got two other inputs; perhaps other ursers?

Academic interest in bitcoin only. Not owner, not trader, very skeptical of its longterm success.

That address is listed here near the very end: http://johoe.mooo.com/bitcoin/broken.txt

And johoe said that he didn't swipe them all:
The scale is also much bigger (500 addresses in one day, >200 BTC).  I still count almost 300 unspent outputs (but I'm too lazy to swipe them all).

So I guess somebody else did... Too bad. But maybe it's another Good Samaritan.

Yeah, somebody else took it:

joehoe has been an absolute huge help. I had 100 coins stolen, unfortunately after speaking to him he didn't catch my address.

Your parents should be proud of you, johoe!

Arguing that you don't care about the right to privacy because you have nothing to hide is no different than saying you don't care about free speech because you have nothing to say.

There was a tx signing bug in BitcoinJs which Counterwallet (a Counterparty web wallet) triggered. Counterwallet has been patched, and all users of Counterwallet should indeed generate new accounts and sweep all of their funds there.

See the original announcement.

Just quoting this in case anyone is confused about the whole situation. The issues affecting Blockchain.info have nothing to do with Counterwallet, and everything has been fixed there since ages.

If you could return the funds to address 15tXHJCjehqCEL6zRCkGwvuDY6YzZV5sKP that would be fantastic.

I should also add if that using our admin tools, if users supply us with the correct wallet information, we are able to accurately determine which refund claims are valid and which are not. So far we have processed over 30 refund requests and will be processing more over the rest of this week.

I cannot express my gratitude towards you. Thank you so very much for this. Sort-of a "Faith in Humanity Restored" moment right now.

Do you mind posting a Bitcoin wallet. As soon as I get the coins back from BlockChain.info; I'll be sure to send something.

Thanks! Rep ++ left.
