I found my lost seed and recovered my electrum wallet; only to find that wallet had been emptied. 10.78134 BTC gone, now 0. Can anyone explain to me how that is possible. How did someone successfully hack my account.
Option 1. It may be that you've stored the seed somewhere somebody else had access to it. One of the most common mistakes is to store the seed in electronic systems - cloud, e-mail and so on.
Option 2. Your computer is infected. A malware can look for specific files, a malware can record your keystrokes.. and send everything to its master.
Option 3. You didn't pay attention, you have downloaded a malicious Electrum and also didn't check the signature.
Since the wallet is only a tool handling the keys to your coins, it's not necessary for somebody really access your computer, instead, just by having the seed he can recover to another wallet and spend your funds from there.
I'm really sorry for your loss, it's a huge amount you should have known to keep it on cold storage or at least hardware wallet.
