<p> Browsers are used as a medium to perform various activities on the Internet and mobile applications are used on mobile devices. They let users connect to the Internet and access different services such as sending emails, watching videos, using banking services, etc. The increase in the usage of the Internet, personal computers, and mobile phones led financial institutions to democratize their services and provide omnipresent and cost-effective services to their customers, in turn attracting a large customer base. Many of these financial institu?tions store and manage sensitive user information such as account numbers and usernames, passwords, Social Security Numbers (SSNs), etc. Due to the nature of the sensitive infor?mation that these institutions manage, it makes a perfect bait for attackers to exploit and perform cyber attacks. Most of the forensic and security research observed in the bank?ing ecosystem focused on foreign financial institutions and mobile banking applications for Android. However, no forensic research has been conducted on the mobile and browser ap?plications of US financial institutions. In this research, I performed a forensic analysis on both browser and mobile applications (both Android and iOS) of US financial institutions. I conducted a forensic investigation on the JP Morgan Chase (Chase), Purdue Federal Credit Union (PFCU), Discover, and CapitalOne banks. This research found what information these banking applications store locally and where they store them to assist digital forensic investigators in investigations. </p>
