Avira USSD Exploit Blocker
Prevent an unwanted USSD wipe of your phone or sim with this simple new app.
USSD codes are keypad commands that can be used to access a variety of phone functions, from checking minutes to accessing expert controls.
Malicious web pages have recently exploited USSD Android functionality. By tapping the wrong web link or scanning a bad QR code, an unsuspecting user can execute a USSD wipe that disables the SIM card or even executes a factory reset, also known as a dirty USSD hack.
Fortunately, Avira now offers a USSD Android exploit detection app. It’s a free and easy way to protect your phone and sim card’s contents from unauthorized deletion.

Don’t let that smartphone get too mobile!
Keep your phone in good hands just in case it leaves your hands.
