Malware can be deployed remotely over the web and is supposed to work on the latest iOS 5. Malware will be demonstrated next month at the upcoming International Malware Conference, MalCon in Mumbai, India. The malware works on jailbroken devices – something which over 90% of users have.

The malware can not only intercept calls of users, steal data but also provide a reverse VNC to see remotely all the actions of the victim.
