A modified version of Android malware has been discovered by IBM Trusteer researchers on websites where users end up after getting smishing (SMS) messages.
The BrazKing Android Banking Trojan offers modified and new tactics that ensure smooth operation without risky permission requests. It uses the screen dissection function to show which apps are installed on an infected device.
This overlay ensures that it connects to the command and control server to get the correct login credentials when using the bank app. Its ability to steal 2FA codes, login credentials and screenshots, bypassing various permissions makes it a very powerful banking Trojan.
During the installation process, users are prompted to update their device to the latest version as soon as they arrive at corrupt third-party websites.
If a user agrees to the “download from unknown sources” option, the malware is dropped on the device after which they request access to the ‘Accessibility Service.” Once permission is granted, the malware will then be able to carry out various malicious actions including dissecting the screen programmatically; keylogger capacities; RAT capabilities; reading SMS without the ‘android.permission.READ_SMS’ permission, and reading contact lists without ‘android.permission.READ_CONTACTS’ permission.’
