What's the best tool to crack a Blockchain.info version 0 wallet? https://github.com/magnumripper/JohnTheRipper/issues/2164 says use btcrecover https://github.com/gurnec/btcrecover/issues/97#issuecomment-322803105 seems to suggest JohnTheRipper So which is it? I have tried btcrecover using the tokens which I thought were in the password without success. So will need to try a dictionary approach (1-2 words followed by 0-4 digits). Also, i seem to have two different versions of the same wallet.aes.json. The one they sent in the original email in early 2012 and the one that is downloaded when i call the https://blockchain.info/wallet/{id}?format=json&resend_code=falseHow can this be, unless they held the original unencrypted wallet and use two different methods (e.g. different PBKDF2 key stretching)? Finally, can anyone tell me whether the 10 character minimum password length was mandatory during early 2012? |

The site says this today.... fingers crossed
Important Notice About the Allcoin.com Takeover
Dear Allcoin customers, thank you and other customers being with us until now, we did have troubles a month ago and we have to close the exchange temporarily.
Our team has received an offer from a very strong company in the industry. After comprehensive consideration, we believe that the acquisition will be Allcoin's best choice.
The new website will replace Allcoin's site system, all user accounts will be reserved. However due to the system switching user assets will not be transferred directly to the new platform, therefore please make sure to withdraw all your Allcoin digital currency funds within 30 days.
Because we've sold out the domain, so we'll use another domain to withdraw you coins in one or two weeks, then you can find the withdraw domain on this page. We'll try our best to fix the wallets and withdraw your coins.
Thank you for your support. In future new AllCoin.com will provide a better service for you!
AllCoin Dev team.

That's a nice find.
That 5 btc balance has accumulated by weeks of deposits. There hasn't been any withdrawals for over a month.

I almost closed my allcoin account numerous times in the past 12 months. My account kept getting frozen and the penultimate time was a few months ago when it took a couple of weeks for Mark? to unfreeze my account. It was pretty obvious it was a one man operation. I also didn't think he was making that much money. The volume of all the alt coins on this exchange has always been very small (going by http://coinmarketcap.com/exchanges/allcoin/ - this doesn't show historic volumes). And if he was only making 0.5% of that, well I did wonder how long he would be motivated. So I reduced my holdings there from 4 to 3 btc. I couldn't bring myself to close out because I had made over 3 btc in the previous month. I reasoned that as it was "profit" it was worth the risk. Greed over sense. I've been taught that old lesson again. Still I would like to believe in Mark's integrity, he didn't strike me as a fraud. I therefore would give him the benefit of the doubt and say the closure might be from sudden illness, or 3rd party theft of coins scenarios. |

Would the SSL cert change require manual intervention?
Might it be a hosted solution so that this is handled by a 3rd party?
I have seen reports in other posts that some support was done about a month ago.
Anyone's guess.

Has anyone had a response from allcoin support within the last 30 days?
I won't speculate as to the reasons, but this exchange does not look like a good risk.

Allcoin has been reasonably profitable for me in the past, so even though I stand to lose 17% of my total coinage, the potential closure of the exchange itself is more saddening.
I still hold out some hope, while the site is operational.

from the sound of what the ceo said that they are moving the bitstamp environment to a more secure server location means that the physical servers were not so secured.
where do they keep their physical servers ?? in their moms basement ?? seems like bitstamp should at least be PCI compliant which means their servers need to be physically secured.
when they do an 'audit' then they need to do a security audit. if their stuff is not secure then they should not be in the business. hiring the engineer is expensive but cheaper than losing 5M a year.
from what i have read it sounds like someone walked in to their datacenter (or moms basement) and stuck a flash drive into the server and walked away with the wallet.dat file.
i not saying that is what happened but gathering what the ceo said and what i have read it sounds like maybe that what happened. whatever the case is they did not have sufficient security.
and what to do if the engineer or auditor cannot resist £5m? if someone walked into their datacenter and used a flashdrive, then they are probably in a police cell as we speak. unfortunately the law in the uk takes a long time, which doesn't bode well for a quick resolution. |

i suppose i had a lucky escape, i never saw reason to keep coins in the bitstamp exchange. i traded out of my bitstamp iou's on rippletrade when the prices went out of sync. i had to take a poor ask price in ripples but at least i got my money. the bitstamp gateway was open long after the initial announcement, and i thought i was being a little paranoid by bailing out with a haircut of about 2%.
now my ~bitstamp iou balance is nil, i had some dust in there. will be interesting to see if it comes back. anyone else see this?
Bitstamp has 200,000 BTC in reserves. Unlike Gox, they only lost a small percentage of total bitcoins during this hack so I think customers' deposits are safe. Poloniex suffered a similar hack which saw them lose 12.3 percent of their total BTC. They made it out fine. Smells like fractional reserves... yes, i agree. it is similar. now, a hacker cannot steal a digital iou, as they could only redeem it from the issuer who would recognise it as stolen and not accept it. the often cited weakness in ripple iou's has benefit in this case. |
