Some third party BlackBerry 10 apps are security risks
Other high risk apps named in the report use a multiple of the bandwidth that the original app uses, indicating that user data is being submitted to an analytics site. Nemory Studio's Twittly submits analytics and data from Google Translate. Personal data belonging to Twittly users is being sent in plain text over HTTP making it easy to steal. 10 ads per second are sent to Smaato although none are seen by users.
BlackBerry users need to stay away from those third party apps that were found to be a poor security risk. It is amazing when you think about all of the machinations that go on behind the scenes. If you currently have some of those high risk apps installed on your 'Berry, you might want to uninstall them now.
