  There is a rapid increase in the number of mobile banking applications' users
due to an increase in smart mobile devices. Mobile banking is a financial
transaction and service offered through mobile devices. Almost all financial
institutions now provide mobile banking services to their customers. However,
the security of mobile banking applications is of huge concern because of the
amount of personal data and information they collect. If an attacker gets hold
of personal information, they can access bank payment or card accounts. This
research aims to analyze the vulnerability of the UK digital banks'
applications to identify vulnerabilities in the apps and proffer
countermeasures that can help improve the security of the bank applications.
Androbugs, a vulnerability scanner, was used to analyze the vulnerability of
six digital banks' android applications. Starling, Monese, Atom bank,
Transferwise, Monzo, and Revolut were scanned. All the scanned digital banks'
applications have vulnerabilities; however, some have more vulnerabilities than
others. For example, Revolut's mobile application has the highest number of
identified vulnerabilities. Therefore, there is need for more security in the
digital banks' applications as well as other mobile banking applications.
