I work IT... I know what a backdoor is. What info are you gonna get from me (or normal home user) with a backdoor? Even if you get a keylogger in through a back door, you can't even get into my bank account because multi-factor authorization. Hackers are looking to exploit vulnerabilities and back doors when trying to get into company resources, but home users very very very very rarely. The reason people get hacked is from phishing / social engineering and also using the same password for a site login that's the same as your email login. If xyz.com gets hacked and they find your login info (usually email) and your password, then that password is the same as your password for your email address, they can have a field day with that. You have to have tiers of passwords (super important stuff like banking, then email passwords have to be really secure, then like shopping sites that have attached cards/accounts to them, then stuff like Reddit or Escapist) and they can't overlap like a Venn diagram because you can't have say the Escapist getting hacked and then someone knowing your email password basically.
