A new banking trojan named ‘SharkBot’ has been seen targeting Android devices.
The malware exploits the Accessibility Services feature on a device, and uses this to grant the threat actor control over legitimate banking apps installed on the phone. This allows the user to auto-fill fields in valid mobile banking apps and carry out money transfers from the compromised devices to a money mule network controlled by the threat actor.
The malware is designed to attack 27 targets — including 22 international banks in Italy and the U.K. and 5 cryptocurrency apps in the U.S. It appears to be in the early stages of development, with no overlaps found to that of any known families.
SharkBot is used to initiate money transfers from compromised devices, bypassing existing security controls.
The attackers can also acquire sensitive information from apps such as credentials, personal information, current balance, etc.
– Android Devices
No samples of the malware have been detected on the official Google Play Store. The malicious apps are thought to be installed on users’ devices either via sideloading or social engineering schemes.
The malware is disguised as a media player, live TV, and data recovery applications with names such as:
– Live Net TV
– Media Plater HD
Be aware of these applications, especially those that are NOT on reputable sources such as Google Play Store. Make sure you are not downloading applications like these on a random and potentially dangerous unknown platform.

SharkBot uses similar techniques to other banking trojans such as UBEL and TeaBot.
UBEL – This Android malware was observed in January 2021 exploiting accessibility services to steal from European banking applications. The codebase was then apparently forked and used in a separate botnet called OSCORP seen as part of a campaign in May.
TeaBot – Another Android banking trojan that stole users credentials and intercepted SMS messages in order to commit financial fraud against banks in Spain, Germany, Italy, Belgium, and the Netherlands.
Although SharkBot uses a new codebase, it continues the trend of banking trojans abusing Accessibility Services.
