I saw many people's account are hacked any how.My question is how can anyone hack accounts? And how we can protect our accounts? I don't know if this topic should be written here but i really need these answer.
There was a database leak in 2015. My guess is most of these hacks are related to this database leak.
I don't think that database leak in 2015 is the main reason of high number of hacked accounts. As I see, biggest number of hacked accounts was made after 2015. So, probably main reason of account hacks is phishing websites and people using weak passwords.
