Given their incredible seasons, it\u2019s no surprise that the big game will be featuring the Denver Broncos and Carolina Panthers, two of the best defenses in the NFL. While they battle it out on the field, fans will be watching on lots of mobile devices, so\u00a0Appthority took a look at the official team mobile apps to see which one offers the best security.Appthority was started early in 2011 by well versed security professionals who noted the growth of apps in the workplace. While many apps were created for social uses, the explosion of apps on mobile devices has created a lot of risk for enterprises.Those risks are not always malicious and can range from undetected issues in the software developing kits to unintended mistakes from developers. Appthority uses an analysis engine and searches hundreds of thousands of apps for vulnerabilities to find out what risks live in the devices.To prove that security isn't always about finding the bad guys, the Appthority team decided to have a little Superbowl fun. Here's what they found when they analyzed apps that will be heavily used on Sunday.Of the more than 20 Super Bowl Apps tested, the Carolina Panthers Android\u00a0app\u00a0exhibited more risky behaviors than their Super Bowl opponent, the Denver Broncos 365\u00a0app.Be careful if you plan on streaming the game live on the CBS Sports Android\u00a0app\u00a0as it was found to have the highest amount of risky traits.The NFL Fantasy Football\u00a0app\u00a0for Android had the highest combination of risky behaviors, including background access to the phone and device configuration.Domingo Guerra, president and co-founder of Appthority said, "Overall we analyzed every app through our complete set of engines, looking for over 100 different traits from malware to location finder."Because reading your location is different than sending your address book, they applied different weights based on what the apps are capable of doing, so their scores were determined by behaviors.\u00a0They found the CBS app risky, "because of the number of behaviors it was capable of doing. It didn\u2019t have malware, but did have traits we are seeing more and more\u2014like being able to run in the background," said Guerra.The concern with running in background is that these apps are collecting audio or video. It's a behavior tantamount to cookies on a website.\u00a0One other behavior of particular concern to the enterprise is the ability to access the calendar, which Guerra said is not necessarily required for functionality. "The calendar has a lot of information that could be confidential. Dial in numbers, passwords, topics," said Guerra. \u00a0While some might feel indifferent about this behavior, it's worth pausing to think about what access to a calendar can reveal. Appointments, dial in numbers, passcodes, contact information. Topics being discussed in a conference call. All of which can result in a breach of more critical data.The CBS app also sends PII, and Guerra said, "It's one of the few apps that did. Your name, birthday, username\u2014it was encrypted, but it is concerning. More 3rd\u00a0parties can potentially gain access to our personal data and track our locations."The most alarming behavior is that the app replaces a random number generator, "which is not following best practices for security," said Guerra. "Android and iOS create a random number generator specifically to help with encryption," and replacing that number can create encryption problems, which makes the app more vulnerable.[ ALSO ON CSO:\u00a0 Network security vs. app security: What's the difference, and why does it matter? ]So, the final prediction if we are basing the outcome of the game on the strength of their app defense, "The Broncos app has a little better security because it showed fewer risky behaviors," said Guerra. "Neither is sending PII. One is tracking location the other isn\u2019t, but the Panthers app replaces the random number generator."Maybe users are thinking,\u00a0it's just a team app, but if they are logging in with the same username and password that they use on other applications, websites, or networks, the risky behaviors of that team app become far more important to enterprise security.If you didn't have your money on the Broncos before now, perhaps you want to hedge your bets, just don't use the NFL fantasy football app to do it.
