Original Reddit Post:
So on the 6th of January I spent around half my wallet online time stamped at 18:53. After returning to my wallet yesterday on the 8th there was a transaction made from my wallet on the 7th time stamped 00:56 that I never sent. I use Electrum Wallet version 2.7.12 and note all my transactions hence I know this is not me. How can I have lost bitcoin? Has my computer been accessed remotely? Can you even hack a bitcoin wallet? I can confess I am a newbie when it comes to this, so don't even know where to start to try and get my money back, if I can, and how to prevent whatever has happened from happening again.

Update:

Been told to search on here for more answers, and learnt about this exploit that exists in anything below version 3.0.4 of Electrum. Where do I go from here? Obviously I am now updating my wallet, however how can I retrieve my stolen bitcoin?
