Dumpster diving refers to the practice of rummaging through trash or discarded items, such as dumpsters, trash cans, or recycling bins, to find valuable or sensitive information. Attackers or individuals engaged in dumpster diving may search for discarded documents, receipts, bank statements, invoices, or any other materials that contain personal information, account details, or confidential data. The goal is to gather information that can be used for various purposes, including identity theft, financial fraud, or corporate espionage.
