ISIS Is Hijacking Western Twitter Accounts To Rebuild Terror Network
Email platform used by Sony hackers is a key part of the process
ISIS is coaching its Twitter army to hijack dormant Western Twitter accounts to evade the microblogging service’s cull of jihadi accounts. Twitter suspended more than 1,400 ISIS accounts since the group released the first video of Kenji Goto, the late Japanese hostage, two weeks ago. Over the past month, Twitter has also purged tens of thousands of ISIS-related accounts. ISIS supporters are circulating a new social media guide with instructions for acquiring accounts undetected.
The guide gives step-by-step instructions on how to claim a dormant Twitter account using “disposable email” platforms such as YOPmail.com or Moakt.com. Hackers involved in the recent Sony data breach used YOPmail.
Users are instructed to pick a dormant account with a Western name and use the email platform to phish for the email address originally used to set it up. Once successful, they can turn it into a new ISIS account after changing the username, password and picture.
Then the guide instructs users to pick a prominent sheikh with ISIS affiliation and a working Twitter account. The guide gives instructions on how to auto-follow their followers en masse using a script injected into the page. The theory goes that some of them will follow back, expanding the user’s circle of followers and plugging them back into the social network of ISIS supporters.
