Shut the fuck off, dont you see that this thread is from MAY 2017? are you blind? Or you are simple just not reading the entire thread before posting? came on, do not be so lazy, what a shit poster.
As long as oyu kept your keys safe, this is impossible to happen. So it's most likely someone has either access to your pc or you go infected with malware that can steal data i.e. keylogger.
And you do not need to be an expert to know that you can not share your private key, and that you need to keep it safe, are you a newbie or what? I am tired of this kind of people who are always trying to justify everything without not even knowing how to use an offline wallet.
