Re: [Emergency ANN] Bitcoinica site is taken offline for security investigation May 11, 2012, 01:32:55 PM #7 Quote from: znort987 on May 11, 2012, 01:22:52 PM Quote from: zhoutong on May 11, 2012, 01:16:37 PM Today, we have discovered a suspicious Bitcoin transaction that doesn't seem to be initiated by any one of the company owners. Some of them are not online at the moment so this is not conclusive.



Suspicious transaction:



{

"account" : "",

"address" : "182tGyiczhXSSCTciVujNRkkMw1zQxUVhp",

"category" : "send",

"amount" : -18547.66867623,

"fee" : 0.00000000,

"blockhash" : "00000000000003f6bfd3e2fcbf76091853b28be234b5473a67f89b9d5bee019c",

"blockindex" : 1,

"txid" : "7a22917744aa9ed740faf3068a2f895424ed816ed1a04012b47df7a493f056e8",

"time" : 1336738723

},



We have contacted Rackspace to suspend all our servers and lock down our accounts. All your trading and financial data is safe (as far as I know), apart from the Bitcoin loss.



Thank you for your patience and understanding while we investigate this issue in detail.



It's really hard to believe that after the linode debacle, you guys are

still leaving that many coins on hosted systems.



Please learn about offline transactions and how to properly decouple

the wallet from your trading system.



Reading the armory threads would be a good place to start.

We have over 80% of our Bitcoins in offline wallets at the moment before the attack. We had to keep a large balance because the withdrawals are huge! We have over 80% of our Bitcoins in offline wallets at the moment before the attack. We had to keep a large balance because the withdrawals are huge!
