Researchers find security flaw in Blackberry Playbook

Researchers from the Intrepridus Group have found out a security flaw in the bridge feature of the Blackberry Playbook tablet which could potentially let hackers have complete control over a user's email and calendar. The researchers explain that the Bridge feature involves token files for authentication. Due to a bug in the OS , these token files are accessible in a file which is readable by all users. The chances for damage however remain minimal as the hack requires the presence of a malicious app on the tablet before the hacker can do any damage. RIM has already closed the security hole in its upcoming Playbook OS 2.0 update.
