Understanding LeakerLocker Ransomware Attack


LeakerLocker is a ransomware that affects mobile devices running on android platform. Unlike other mobile ransomwares that encrypt user data, LeakerLocker Ransomware doesn’t encrypt your data but locks your screen. Cybercriminals claim that the user’s private & confidential information will be transferred to their secure cloud and sent to the victim’s phone contacts if he fails to pay a ransom amount.

The mobile malware research team at McAfee identified the LeakerLocker ransomware on July 7, 2017. It was spotted that the ransomware was spreading via two apps:

  • Wallpapers Blur HD
  • Booster & Cleaner Pro

The apps function like any legitimate app; however once installed, a malicious code is loaded via a command-and-control server. When the access permission is granted, the code collects sensitive data from the user’s phone and blackmails him against it.

What Type Of Data Is Collected?

  • Personal photos
  • Contact numbers
  • Sent and received SMS
  • Phone call history
  • Facebook messages
  • Chrome history
  • Full email texts
  • GPS location history

How To Protect Your Device From LeakerLocker Ransomware?

  • Install An Antivirus Software: Protect your phone from any ransomware attack by installing a reputed antivirus software. These software scan the websites as well as apps to ensure that they are safe and do not contain any type of malware.
  • Update Your Phone: Make sure that you check your phone for android system updates available and download them regularly.
  • Back-up Your Files: It is important to back-up your files regularly to recover them in case of any data loss. You can back-up the information to the cloud or store your data on an external hard drive.
  • Don’t Download Apps From Unknown Sources: Whenever you download an app, make sure that you download it from a trusted source. Avoid downloading third party apps as they may pose a security threat. Also change your system settings and disable them to perform unofficial app installations.
