Background
Avira describes Hydra as an Android BankBot variant — malware created to steal banking credentials. It works by prompting the victim to grant dangerous permissions like accessibility, then, each time a banking app is launched, it overlays the genuine login screen with a fraudulent one. The objective is to fool the user into typing their login details, which are sent directly to the operators.
