You mean like the IT guy running the DNC email server and his password was...(wait for it) PASSWORD?...They claim the most vulnerable sites are Christian and other religious sites that spend far less on security. And because people in those groups tend to be more trusting and have more money.
Or when HC bleached her private email server before giving it to the FBI and Julian Assange told them not to worry, he and the rest of the world had a copy of all of the messages?
Being safe is not that hard:
1. Don't install anything.
2. Don't click on links in emails.
3. Use a different password for login at each different place.
4. Don't open attachments that are from a source that you cannot verify.
4a. Anything that is actually important will be a letter in your mailbox.
5. Have a good defense like McAfee running just in case some idiot sits down at your keyboard.
