Which term describes the unauthorized access through an access point in a wireless network?

The term that best describes unauthorized access through an access point in a wireless network is "interloping." This term refers to the act of someone entering a network without permission, typically exploiting vulnerabilities in wireless security protocols such as WEP, WPA, or WPA2. Access points can sometimes be left unsecured or improperly configured, allowing unauthorized individuals to connect to the network and potentially gain access to sensitive data or resources.

Phishing pertains to deception techniques aimed at tricking individuals into revealing personal information, so it doesn't describe access via a network node. Exfiltration refers to the unauthorized transfer of data out of a network, while eavesdropping describes the act of intercepting communications, which may happen once unauthorized access is established but does not specifically involve gaining access through an access point. Therefore, interloping is the most accurate term for the action of unauthorized access through a wireless network access point.
