What is USSD?

The purpose of USSD codes is that telecom operators can provide distance support for phone devices. An example of such code is one that displays IMEI number (*#06#), but there are also USSD commands that can wipe all data and restore a phone to factory settings.

How can USSD attack be launched?

Protection against USSD (Unstructured Supplementary Service Data) attacks is an essential security layer for Android devices, since these attacks can be easily initiated by all means that lead to visiting a website containing malicious USSD command such as SMS, QR code, or simply by tapping a fraudulent link in the browser.

How does ESET USSD Control protect you?

By checking for malicious codes before they are executed, ESET USSD Control makes sure that all data on your Android phone stay safe. The app displays a warning window each time a malicious USSD code is found, blocking the execution of the potentially harmful command.
