Security firm viaForensics has discovered security vulnerabilities in mobile banking smart-phone apps for Google’s Android and Apple’s iPhone. Apps from Bank of America, Chase, TD Ameritrade, USAA, Wells Fargo and Vanguard were all targeted by the firm. Some apps also inadvertently saved passwords, because of the lack of encryption, and some saved data to the phone that had previously been viewed in the app itself. The firm noted that some apps do not validate security certification, making them susceptible to so-called man-in-the-middle attacks.”]
