If you're using some social network service like Twitter, Facebook, Google+ you've probably seen your friends posting weird click-bait sites. Maybe you've felt into the trap too.
I've prepared simple demo website that reveals how is it possible, you click "Like" button without even knowing it:
The worst thing is: It's extremely easy to prepare such website. Attacker can make you to click "Share", "Like", "Share on the group, you're member of".
How to protect my accounts?
Like button will be there, but you won't be signed in.
This will boost your security and limit data transfer. Like/share boxes won't load at all.
• Never click anything on suspicious websites.
