USB Blocker: Anti Hack & Juice Jacking Protection

Public chargers, unknown USB cables, and shared power banks are being used to silently hack phones. Hackers insert malicious USB cables that look identical to normal chargers — plug one in and spyware, malware, or keylogging commands can be injected into your device quickly. STOP before you connect.
USB Blocker is an anti hack security app that protects you from juice jacking, hacking cables, and malicious USB devices. It detects and helps block the attack instantly — keeping your data security and privacy intact.
Whether you are at an airport, hotel, office, or a friend's house, USB Blocker works silently in the background to protect you the moment you plug in.

What is Juice Jacking?

Juice jacking is a cyberattack where hackers use public charging stations or malicious USB cables to steal data, inject malware, or install spyware on your device without your knowledge. USB Blocker is your juice jacking blocker — detecting and stopping these attacks before they reach your data.

Hacking Cables & Malicious USB Detection

Some USB cables are built specifically to hack your device. OMG, that cable charging your phone might not be a charger at all — hacking cables act as a hidden keyboard, injecting commands and installing malware or spyware remotely over Wi-Fi. USB Blocker detects when any USB cable or device attempts to inject commands and stops the attack immediately.
+ Detect hacking cables that simulate keyboard input to inject malicious commands.
+ Block USB-based keylogger attacks — stops injected keystrokes before they execute.

Privacy & Data Protection:
"This app uses Accessibility services."
This app requires a service for being able to detect when hacking cables are trying to inject commands so it can stop hackers and spyware. Since normal service can't detect when malicious cables push physical keyboard events we need "Accessibility services" for doing that. It does not do anything apart from detecting when physical keys is pressed to protect you. We don't collect or share any personal data using that service.
