Which technique involves sifting through garbage to find sensitive information?

The technique that involves sifting through garbage to find sensitive information is known as dumpster diving. This practice is often employed by attackers to gather confidential data, such as discarded documents with personal information, account details, or company data, which can provide insight into a target's vulnerabilities. They seek out anything that may have been improperly discarded, including physical documents or discarded electronic devices that could still contain data. By recovering this information, attackers can potentially use it to launch further attacks, conduct identity theft, or gain unauthorized access to secure areas or systems. This emphasizes the importance of proper data disposal and secure document shredding to protect sensitive information.
