Theres really not a whole lot anybody can do to prevent being hacked. You install your firewall, your AV, your anti-malware, you back up regularly. Then you sit back and watch it happen anyway.
One of the NSA memos that was on wikileaks says it all. When Congress ordered the NSA to help private industry create the strongest cyber security protocols possible back in the 1980s, the NSA immediately set about to sabotage all computer security. They deliberately sabotaged every security protocol since the 80s. And now we're supposed to think they're not responsible for all the security holes these days? They may not be doing all the hacking, but they sure had a hand in many of the holes hackers are using these days. You think they learned their lesson? You think they're not doing it anymore? Only a fool would trust anything the NSA says or does anymore.
For my part, I remain as anonymous as possible. I refuse to use social media and only give out throwaway email addresses. Yes, I use credit cards online, but they're prepaid throwaways and often depleted after two or three uses. I refuse to link accounts to one another. That cuts me off from posting at a lot of forums. But not getting targeted is more important than expressing myself.
