A detail information on how he hacked you Will be welcomed. For others to learn to avoid such mistake
initially I follow bounty on one website .. I forgot what the name of the website .. just fill in the address and email course conditions. after that there is an incoming email from the website itself. I open the email there is a gmail team warning that the email I received contains a fishing virus .. but already click that email. the next day when I checked the wallet was empty..
Never ever open emails without the real address of the company itself.
This is all your fault.
There is enough warning for everyone and this is actually an old style of an attack.
First ones where the slack channels which have a different MEW website URL and then this one.
Now you know what to do next time. I bet he already cleaned up your address with all your funds.
