Jane invites her friends Alice and John over for a LAN party. Alice and John access Jane's wireless network without a password. However, Jane has a long, complex password on her router. What attack…

Wardriving is the act of driving around to discover and map wireless networks, not an attack that grants unauthorized clients access to a network.

Wireless sniffing involves passively capturing and analyzing wireless traffic on a network, not creating an open access point that clients connect to.

An evil twin attack involves an attacker setting up a rogue wireless access point that impersonates a legitimate network (same or similar SSID) but without the original network's security controls, such as a password. Alice and John unknowingly connected to this rogue AP instead of Jane's legitimate, password-protected router, which explains how they accessed 'Jane's network' without her password.

Piggybacking refers to someone physically gaining access to a secured area or network by following an authorized person, not setting up a rogue wireless access point.
