Well, I had my accounts hacked in Bittrex and HitBTC by 24th July. The hacker also tried to hack into Poloniex, but this one asks for a code sent by email.
It was my fault, I used the same password in the three exchanges, and I was not using 2FA, a foolish attitude from my part. The hacker messed my Bittrex funds, he sold everything he could for bitcoins, except the altcoins below 50k satoshis in value. However, he was not able to withdraw it from Bittrex, since this would require a confirmation by email. I had nothing stored in HitBTC.
The interesting part is that I also have a account in Btc-e, and if I'm not mistaken I was using the same password there too. The attack was nearly the same time people reported Btc-e shutting down.
The exchanges sent emails with logging information, but not Btc-e. The hacker used a proxy and Chrome as browser.
