Almost everyone with a smartphone knows there’s some risk to carrying around apps that handle passwords, email, photos, personal info, and access to financial information on a device that you can easily leave unattended on a desk or sitting on a counter in a coffee shop. But just how many apps put users at risk? According to Chicago-based digital forensics company ViaForensics, a lot: their new Mobile App Security study finds that a full 10 percent of Android and iOS apps tested store passwords as clear text, completely unprotected if anyone should get ahold of a device. Furthermore, some 76 percent of apps tested store usernames in plain text—and while usernames might not seem terribly important to secure, sometimes they’re just the info a criminal or stalker needs to get to more-important info.
“Based on the results of this study, there is a serious potential threat for identity or financial theft if a lost smartphone should fall into the wrong hands,” ViaForensics wrote. “For instance, if a cybercriminal is able to steal one password, coupled with all of the usernames recovered, would pose a serious threat for someone who uses the same password on many accounts.”
ViaForensics rated apps on a three-stage Pass-Warn-Fail system. A “Pass” rating meant that the company couldn’t find sensitive data it was looking for, or if the data was successfully encrypted. ViaForensics gate an app a “Warn” rating if they were able to uncover data but didn’t believe the exposed information put the user at significant risk, while a “Fail” rating meant ViaForensics was able to pull information like passwords and accounts numbers.
Of the 100 apps tested, 39 received a failing grade. Some 44 apps rated a warning, and only 17 got a “pass” rating.
Broken down by category, some 32 financial applications faired relatively well, with 14 passing and 10 receiving a warning: that means eight failed, including Mint for iPhone and Android, along with Wikiinvest and Square for the iPhone. Social networking apps, however, failed miserably, with none receiving a passing mark and a stunning 14 out of 19 failing. Retail apps also faired badly: of 14 apps tested, none passed, 12 for a warning, and 2 failed.
Overall, ViaForensics noted Apple made significant headway with iOS security with iOS 4.0, but notes that iOS users can’t afford to sit back and ignore potential risks from apps.
