Android devices have once again been hit by a new form of malware. This time the culprit is a mobile variant of the Zeus banking Trojan that steals banking passwords. Zeus and another malware package, SpyEye, "are the most malicious threats to financial institutions and their customers," Mickey Boodaei, president and CEO of Trusteer, told TechNewsWorld. Over the past year, 72 percent of the 3.2 million desktops Trusteer's Rapport service disinfected were found to host various versions of these two malware packages, Boodaei said.
