wiredmikey writes "Researchers have recently discovered a new sophisticated and resilient mobile threat targeting Android phones that is said to have infected about 500,000 devices, mainly in China. Called 'SMSZombie,' the malware is stubborn and hard to remove, but users outside of China have little to worry about with this latest discovery. The prime function of the mobile malware is to exploit a vulnerability in the mobile payment system used by China Mobile, making it of little value to the fraudsters outside of China. The malware takes advantage of a vulnerability in the China Mobile SMS Payment process to generate unauthorized payments to premium service providers, and can also remotely control the infected device. It has been spread via wallpaper apps that sport provocative titles and nude photos, and can only be removed using a lengthy process beyond the skills of a typical android user."
