Researchers on Thursday reported that despite a 50% increase in mobile device management (MDM) adoption during the past year, average quarterly exposure to phishing attacks on mobile devices in the financial sector rose by 125% – and malware and app risk exposure increased by more than five times.

In a blog post, Lookout researchers said as more users access cloud services and infrastructure from mobile devices, attackers deliberately target phones, tablets and Chromebooks to increase their odds of finding a vulnerable entry point. The researchers said a single successful phishing or mobile ransomware attack can give attackers access to data across a company’s entire back-end infrastructure.
