Even though mobile malware targeting the Google Android operating system is increasing, actual infection rates are still relatively low, according to cybersecurity experts. Unfortunately, it looks like almost 1 out of every 5 Android apps were "malware in disguise," according to the newest Symantec Internet Security Threat Report.
Over one-third of all Android apps are "madware," or "grayware," designed to increase the number of ads that a mobile user sees. In addition, Symantec noted the first infection by mobile ransomware, which encrypts data on a victim's phone until a ransom is paid.
Android, the No. 1 mobile OS based on market share, has an open infrastructure that makes it even more flexible to use by each phone manufacturer - but also gives cybercriminals the ability to create better malicious apps.
