If you use mobile phone applications like Netflix, LinkedIn, Foursquare, and Square, Inc. - your information might be susceptible to information thieves. In a report I read from Computer security firm viaForensics (found on Consumer Reports.org)...
From 'appWatchdog' there is a new analysis of many popular cell phone applications (apps): 'Improving mobile app security for consumers'.
"Using forensics to improve data security and protect users. Read our findings from objective analysis of various publicly available mobile apps." You can see their list of apps along with an easy to figure out graphic about each app: appWatchdog's Mobile App Security Findings (their legend is posted here).
This is one of the reasons I am choosing not to utilize any app on my mobile devices that requires or uses any of my private data related to banking, finance, etc. I have just read too many articles how mobile devices may be the next target of hackers and techno-thievery.
If you believe you must have or use apps on your mobile device/s (phone or tablet/pad) here is a bit of advice from the Consumer Electronics Blog "Keep your phone with you at all times, and use a different user name - password combination for each account you create"
