Most people I know have had the experience of being hacked into once in their life. Be it their email account, their WordPress blog, their bank account or basic applications - and everyone knows the feeling.
Some people you think are invisible from being hacked, like Google's head of search spam, Matt Cutts.
He shared his story of how and why his Skype account was hacked on Google+. He explains that the Skype account he rarely uses was hacked a month or so ago and he realized recently when he needed to use it for an internet radio show. He said:
As always, it sucks to get hacked. I've talked to a lot of people who have had their website hacked, and it really feels like a violation. In this case, I had a month of distance and the attacker sent me the new password, so it wasn't really that stressful. It does suck that it was Skype's fault though--the best security practices in the world don't help if the vulnerability is on the provider's side. If I had any money stored with Skype, I'd feel more angry and disappointed.
Recently, my company added two factor authentication not just to our emails but to all the web based applications we use at our company that we built from the ground up. This means our web site backends, our financial systems, our timer and task management software, our databases and much more. It adds some piece of mind knowing that there are two steps to get into our secure areas.
But as Matt said, sometimes it is not your fault and it is your providers fault. He pleaded with Skype to add the two-factor method as an option at the end.
So even the best get hacked, in this case, it had nothing to do with Matt Cutts' own doing but everything to do with Skype. You can read the Skype issue at TheNextWeb.
Again, add two-factor to whatever you can! Heck, I even have it on this blog.
