What is the practice of searching for Wi-Fi networks using portable devices known as?

The practice of searching for Wi-Fi networks using portable devices is known as war driving. This term describes the act of driving around with a device that can detect and map out the locations of various Wi-Fi networks, often while collecting information about their security settings. War driving typically involves the use of a laptop, smartphone, or other mobile device equipped with Wi-Fi capability and sometimes GPS to record the geographic locations of these networks.

This practice is often associated with both legitimate and illicit activities. For example, security professionals might engage in this to identify unsecured networks to help inform network owners about vulnerabilities. Conversely, malicious actors might look for poorly secured networks to exploit. This term is well-established in the cybersecurity community and highlights the growing concern around wireless network security in an increasingly mobile world.

The other terms do not specifically reference this established practice or the cultural context behind it.
