One of the most persistent pieces of malware targeting Android devices has reared its head again, this time appearing in 17 apps on the Google Play Store.
As security company Zscaler explains, the apps in question were infected with the Joker malware. It steals SMS messages, contact lists, and device information, but the most serious threat it poses to users is automatic sign-ups to premium wireless application protocol (WAP) services. With WAP billing, users get a shock next time they receive their mobile phone bill as the service costs are charged directly to it.
