Definition and Purpose

Dumpster diving is the act of retrieving sensitive information from discarded materials such as printed documents, sticky notes, hardware packaging, or digital media. While this method may seem low-tech, it remains highly effective for attackers looking to exploit organizational weaknesses. For example, they often target login credentials, employee directories, system architecture diagrams, and old devices that may still store data.

Attackers frequently use this recovered information to launch more advanced attacks, such as phishing or social engineering. As a result, even a single overlooked document can become the entry point for a larger breach. Therefore, organizations must take this threat seriously.

Many companies still underestimate the risks posed by improper document disposal or unsecured physical media. Without shredding policies, secure bins, or employee training, confidential data can easily end up in the trash. Consequently, dumpster diving remains a popular tactic—not only among amateur hackers but also corporate spies and sophisticated threat actors.

GateKeeper Proximity Minimizes Exposure to Dumpster Diving Risks

GateKeeper Proximity helps address one of the main weaknesses exploited in dumpster diving: the presence of written or printed credentials. In many organizations, users write down complex passwords or PINs to avoid forgetting them. These notes often end up under keyboards, inside drawers, or eventually in trash bins.

GateKeeper eliminates this risk by enabling passwordless login through wireless, proximity-based authentication. Users simply carry a secure token to gain access—there’s nothing to write down, remember, or discard. As a result, one of the most common items found in dumpster diving attempts is removed entirely.

In addition, GateKeeper’s centralized credential management system gives administrators complete control over access and audit logs. This removes the need for users to manually manage credentials, reducing paper-based risks. When combined with good disposal practices, GateKeeper strengthens an organization's defense against both physical and digital intrusions.
