New Android ransomware uses clickjacking to gain admin privileges

File-encrypting ransomware applications that target Android devices are becoming increasingly sophisticated. One new such program is using clickjacking techniques to trick users into granting it administrator privileges.

Clickjacking is a method that involves manipulating the user interface in a way that allows attackers to hijack users' clicks and trigger unauthorized actions. It is mostly used in Web-based attacks, where various technologies allow creating invisible buttons and positioning them on top of seemingly harmless page elements.

Due to the restrictive application permissions system in Android, ransomware apps targeting the OS have historically been less effective than on Windows. For example, many of the early Android ransomware threats only displayed a persistent window on the screen with an alert intended to scare users into paying fictitious fines. Most of them impersonated law enforcement agencies and claimed that the devices were locked because illegal content was found on them.
