If you have an Instagram account, you may want to take a closer look at your page. Security experts found these victimized accounts have a different biography, image and name than the original page, and sexual photos were uploaded to instruct others to visit the link of a profile outside the social network. Scroll down for video. Security firm Symantec was the first to spot this new attack on Instagram that takes complete control of these accounts and then changes the user's password.
