Jesus! Well its all gone now, you couldn't expect the hacker to return it of course. Consider it lost forever. All the while you thought its safe when it can actually be faked, its actually easy to fall for it because it looks very legit. I thought its just the online wallet that can be used for phishing, installing a desktop wallet was the safest I know but now, it can be subjected to suspicions.
The Bitcoin codebase is still so young right now and comparable to the early internet. Devs will learn from these mistakes and carry on. I hope no more people loose money to this exploit.
