What areas of our online activities can we expect cybercriminals to target more in the near future?

Mobile devices, gaming and less well known social networks will likely be where the most interesting forms of attack will take place. Over a portion of 2011 and most of 2012, Tumblr saw some really interesting and innovative scams and attacks on end-users; now, those tactics are starting to repeat themselves and slowly but surely the userbase is growing wise. The only solution for scammers is to mix things up a little or go elsewhere, and I'd be surprised if they don't attempt to ply their trade on a newer, smaller social network.
