Figure 96 Rogue AP: Example

13.2.1 “Honeypot” Attack

Rogue APs need not be connected to the legitimate network to pose a severe security threat. In

the following example, an attacker (X) is stationed in a vehicle outside a company building,

using a rogue access point equipped with a powerful antenna. By mimicking a legitimate

(company network) AP, the attacker tries to capture usernames, passwords, and other sensitive

information from unsuspecting clients (A and B) who attempt to connect. This is known as a

“honeypot” attack.

If a rogue AP in this scenario has sufficient power and is broadcasting the correct SSID

(Service Set IDentifier) clients have no way of knowing that they are not associating with a

legitimate company AP. The attacker can forward network traffic from associated clients to a

legitimate AP, creating the impression of normal service. This is a variety of “man-in-the-

middle” attack.

This scenario can also be part of a wireless denial of service (DoS) attack, in which associated

wireless clients are deprived of network access. Other opportunities for the attacker include

the introduction of malware (malicious software) into the network.
