It seems that nowadays most people don’t care about privacy on social networks such as Twitter and Facebook. The new location service rolled out by Twitter and a similar one under development on Facebook, are another source of potential security risks. Tweeting that you are leaving home isn’t such a good idea anymore if you are also sharing your location… It’s almost like leaving your door unlocked.
Other possible threats on social networks are phishing scams of all sorts. Simply by clicking a link you could have your login information stolen, and thus loose your account, with all the private information it contains. Fortunately Twitter is acting to prevent just this. Now all links in Direct Messages and e-mail notifications will be redirected through twt.tl (Twitter’s own URL shortening service) which would enable Twitter to instantly check each link before they are even clicked. And even if they were clicked Twitter is working on a way to protect it’s users.
