Final answer:
A rogue hotspot is a malicious wireless access point set up to mimic a legitimate service, designed to intercept sensitive data like usernames and passwords from unsuspecting users.
Step-by-step explanation:
The type of Wi-Fi hotspot described in the question is known as a rogue hotspot. This is a wireless access point installed on a network without the authorization of the network's administrator for the purpose of deceiving users of a legitimate service. A rogue hotspot mimics the SSID and other settings of a legitimate Wi-Fi hotspot in order to intercept sensitive data from unsuspecting users. When individuals connect to a rogue hotspot, thinking it is a legitimate network, their sensitive information, such as usernames and passwords, can be compromised.
It is important to verify the legitimacy of a Wi-Fi network before connecting, especially in public places. Using trusted security solutions and VPNs can also help protect your data from such threats.
