I monitored Cryptsy Bitcoin and other alts wallets through blockchain analysis and it is pretty hard to me to believe that theft is caused by trojan virus infiltration to cold wallet.

First of all Cryptsy cold wallet then was not cold at all,otherwise how virus jumped to it from server?

Blockchain analysis gave me information that theft began not at 13:37:26 as posted on Cryptsy blog,but 5 hours earlier,through attack on hot wallet.Incident occured at 08:27:48,when someone took 500 BTC through 5 txs of 100 BTC each - https://www.walletexplorer.com/wallet/Cryptsy.com-old?page=1202
These txs were:

Cryptsy employees did not notice that their hot wallet was robbed for 5 hours,when big hack happenned to cold wallet.

One thing is interesting - these 500 BTC did not move at all after it - just like 1000s after big hack.In all BTC hacks till now,hackers never wait more than few hours to put stolen BTC in to the mixer.Except in this case.


Also I found Cryptsy DASH and DOGE main wallets.Cryptsy said that they did not hacked,but what happenned with coins in them.In DASH wallet was 456K DASH.Wallet was formed on 27.July.2014:

It is not hacked and from one of his big direct branches came 8433 DASH sent from Cryptsy on 5th.Oct.2015 to big DASH owner known as Otoh(http://i.imgur.com/Cb2ygx7.png):

DOGE main wallet was also formed on the 27.July.2014 - https://bitinfocharts.com/dogecoin/address/DN27P1saQQ1fYesKP1LHT5MdSXBpgqka85  - there was 9.5 billions of DOGE in it

On 5th.Aug 2014,DOGE was removed from that wallet in multiple 1 billion txs(like BTC in the hack,but as we know DOGE wasnt hacked) :

Plus this withdrawal taken place after Cryptsy lockdown wallets - https://www.walletexplorer.com/txid/85a5d1dfb7fd4589cf43321f65a9ed300e994b4e156653063a1c5912f908c18b


So there are a lot of mystery what is really happened with Cryptsy wallets
