DescriptionNorton Halt is a first responder app specifically designed for your smartphone that alerts you about the latest, breaking security exploits, including the lock screen bypass bug, Exynos 4 processor chip security flaw and USSD code attacks. These vulnerabilities allow attackers to bypass system permissions, gain access to RAM, inject malicious code, install unauthorized apps, and steal your personal data.
The Exynos 4 processor chip, used by several popular Android smartphones has a serious security flaw. The exploit allows malicious apps to gain root access to the system without asking for permissions.
The USSD codes exploit has the potential to initiate a complete wipe of data on your phone and SIM card. Smartphones and tablets running anything below Android 4.1.x (Jelly Bean) are vulnerable. It is highly recommended that you address this flaw immediately, as your mobile carrier may not have provided an over-the-air software update.
• Scan for potential Android OS security risks and exploits
• Prevent lock screen bypass
• 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. (Many competing USSD apps can't do both.)
WHAT IS THE LOCK SCREEN BYPASS EXPLOIT?
An exploit in some Android smartphones may grant full access to the smartphone 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, and is not thought to be a widespread Android issue at this time.
WHAT ARE USSD CODES?
USSD stands for Unstructured Supplementary Service Data and is a session based GSM protocol unlike SMS or MMS. Typically, it is used to send messages between a mobile phone and an application server in the network. 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.
