After viewing wireless traffic, an attacker notices the following networks are being broadcasted by
local access points:
Corpnet
Coffeeshop
FreePublicWifi
Using this information the attacker spoofs a response to make nearby laptops connect back to a
malicious device. Which of the following has the attacker created?

A.
Infrastructure as a Service

B.
Load balancer

C.
Evil twin

D.
Virtualized network

Explanation:
In this question, the attacker has created another wireless network that is impersonating one of
more of the three wireless networks listed in the question. This is known as an Evil Twin.
An evil twin, in the context of network security, is a rogue or fake wireless access point (WAP) that

appears as a genuine hotspot offered by a legitimate provider.
In an evil twin attack, an eavesdropper or hacker fraudulently creates this rogue hotspot to collect
the personal data of unsuspecting users. Sensitive data can be stolen by spying on a connection
or using a phishing technique.
For example, a hacker using an evil twin exploit may be positioned near an authentic Wi-Fi access
point and discover the service set identifier (SSID) and frequency. The hacker may then send a
radio signal using the exact same frequency and SSID. To end users, the rogue evil twin appears
as their legitimate hotspot with the same name.
In wireless transmissions, evil twins are not a new phenomenon. Historically, they were known as
honeypots or base station clones. With the advancement of wireless technology and the use of
wireless devices in public areas, it is very easy for novice users to set up evil twin exploits.
