I Used Cracked Windows 10 Activated (download from internet) on my laptop, and installed Electrum wallet.
Is my wallet safe?
is there a spy on the cracked windows? how do know that Cracked didn't inject malware and spyware, and send the data from my laptop to their server?
You shouldn't use wallet in the same PC, mostly including full of malware and common attacks are keylogger (record and steal every key you type) clipboard (steal content you copy) and the most dangerous when you enter btc address to send payment malware will change btc address. I faced this issue so many time but fortunately lost only few bucks.
I will recommend to read this thread and you will know the world top site offering free crack software is stealing fund through malware
