Norton by Symantec released a free mobile Android app late last year to protect mobile devices against USSD exploit and other malicious security exploit.
USSD (Unstructured Supplementary Service Data) numbers contain * and # and serve the purpose of providing special functions to operators and device manufacturers such as settings reset and wiping the device. There are multiple services based on USSD such as: mobile banking, social networking (Facebook, Twitter), over-the-air mobile software updates, and prepaid/recharge accounts.
Last year, a potential USSD code exploit has been found on some of the Android devices which allow the USSD commands to be executed remotely. It exposes the device to a potential risk allowing the phone to be wiped or factory reset without user’s knowledge.
Norton Halt intercepts any USSD codes that are sent remotely to your device and warns you against the unsafe commands before they are executed.
Norton Halt also protects against multiple types of lock screen bypass exploits. The first type of exploit may grant full access to your device by disabling the PIN/password/pattern challenge feature. Once disabled, the challenge screen will not come back unless the smartphone is rebooted. This exploit primarily affects Galaxy S3, Galaxy S3 Mini, and Galaxy Note II smartphones.
The second type of lock screen exploit may grant momentary access to the home screen or any application running in the foreground from the emergency dialer or the emergency contacts screen when your device is locked. This exploit primarily affects Samsung Galaxy S2’s, S3’s and Note 2 smartphones.
Features of Norton Halt below:
- Scan for potential Android OS security risks and exploits
- Prevent multiple lock screen bypass exploits
- Detect Exynos 4 exploit and USSD code attacks
- Block unauthorized USSD code requests
- Stop the dialer from executing USSD codes without your permission
- Prevent loss of personal data and financial information
- Advanced USSD filtering, including string detection and special characters.
Norton Halt works on all Android smartphone running the version 2.1 and above. Norton Halt can be download from Google Play, link below.
