Quick Summary
Cryptsy lost 13,000 BTC and 300,000 LTC due to an IRC backdoor in the code of the Lucky7Coin wallet.
Details of the Exploit
The developer of Lucky7Coin had inserted an IRC backdoor into the wallet's code, which functioned as a Trojan or command and control unit. This Trojan had likely been present for several months, gathering enough information to execute the attack. Cryptsy was alerted of a decrease in their safe/cold wallet balances of Bitcoin and Litecoin, as well as a few other minor cryptocurrencies, leading to the discovery of the exploit.
