A new malware assault, dubbed the “latest evolution of cellular ransomware,” has been found out affecting Android products. Named “AndroidOS/MalLocker.B,” it lures victims in by posing as well-liked video games or applications on on the internet community forums and third-bash sites.

While its method of circulation may perhaps not be specially novel, the way that this ransomware leverages sure Android characteristics and is equipped to evade detection by most security options marks it out as an revolutionary new threat.

Like the greater part of Android ransomware, MalLocker.B does not essentially encrypt a victim’s documents, as an alternative blocking entry to a system by having about the full display screen with the ransom be aware. If users can not get rid of the malware, they are then left with a option of getting rid of the system or shelling out the ransom.

New threats

Prior illustrations of Android ransomware applied the Process Inform Window to consider about a device’s display screen. Having said that, as security methods grew to become far more sophisticated, cyberattackers experienced to transform their method in buy to keep on being powerful.

The creators of MalLocker.B have employed a two-component mechanism to disable a victim’s system.
