Which practice involves gathering information through unsecured networks?

The correct choice pertains to practices that revolve around exploiting unsecured wireless networks to gather data or access sensitive information. Unsecured networks, such as open Wi-Fi hotspots, do not employ encryption or adequate security measures, making them vulnerable to interception and exploitation.

When discussing the exploitation of wireless networks, it encompasses various techniques that target these weak links, where an individual can capture data packets being transmitted over the network. This can lead to unauthorized access to devices connected to the network, compromising personal information, passwords, and other sensitive data.

The context of the other options highlights their differences from the correct choice. Data breaching generally refers to unauthorized access and retrieval of sensitive data from systems, often through exploitation but not limited to wireless networks. Information gathering can be a broader term encompassing various techniques for collecting data, which doesn't specifically imply the use of unsecured networks. Cyber infiltration typically relates more to penetrating a system’s defenses rather than focusing on the vulnerabilities of wireless communications. Thus, the focus on unsecured networks distinctly aligns with the concept of exploiting wireless networks, making it the right answer.
