Zimperium Uncovers 'DroidLock' Android Malware That Locks Phones and Seizes Control

The campaign targets Spanish-speaking users through fake apps on phishing sites.

Overview

  • DroidLock grants attackers full remote control via VNC, enabling screen streaming and use of the front camera.
  • Deceptive overlays harvest screen unlock patterns and app credentials, allowing lockouts and persistent access.
  • Researchers detail 15 command-and-control functions and abuse of Device Admin and Accessibility to wipe devices or change PINs and passwords.
  • A ransomware-style WebView demands contact via a Proton email and threatens file destruction within 24 hours despite no file encryption.
  • Zimperium shared indicators with Google, and Play Protect is reported to detect and block the malware on updated devices as users are urged to avoid sideloading.
