A mobile botnet called MisoSMS is wreaking havoc on the Android platform, stealing personal SMS messages and exfiltrating them to attackers in China. Researchers at FireEye lifted the curtain off the threat on Monday, describing MisoSMS as 'one of the largest advanced mobile botnets to date' and warning that it is being used in more than 60 spyware campaigns. FireEye tracked the infections to Android devices in Korea and noted that the attackers are logging into command-and-controls in from Korea and mainland China, among other locations, to periodically read the stolen SMS messages. FireEye's research team discovered a total of 64 mobile botnet campaigns in the MisoSMS malware family and a command-and-control that comprises more than 450 unique malicious e-mail accounts.
