Anohana: The Flower We Saw That Day's Naruko "Anaru" Anjō is a pretty eye catching anime character, which is probably why virus writers have coopted the tsundere cutie.
Symantec reports that the Android.Maistealer carrying app requests permission to access contact data, then after the installation process, the malware provides the service it advertised: It allows a user to use the touchscreen to manipulate Anaru's body. Unfortunately, it also steals contact data from the victim's device.
Symantec's Joji Hamada said that spam is directing fans to a website that looks like the official Google Play store. "The app is not available on Google Play, as far as I am aware of, and is only available on these dedicated websites," Hamada wrote.
Mahoromatic's Mahoro might suggest that there's a lesson for dirty minded fans in this.
