Questions and Answers

What is the primary purpose of an Evil Twin attack?

  • To create a backdoor into a corporate network by mimicking a legitimate AP
  • To lure users into associating with a rogue AP, bypassing enterprise security policies (correct)
  • To intercept and decrypt sensitive data transmitted over a wireless network
  • To conduct a denial-of-service attack on a wireless network by overwhelming it with traffic

How does the KARMA tool facilitate an Evil Twin attack?

  • By passively listening to wireless probe request frames and adopting a commonly used SSID (correct)
  • By using a brute-force attack to crack the WEP/WPA encryption
  • By actively scanning for wireless probe request frames
  • By spoofing the MAC address of a legitimate AP

What is a common vulnerability in WLAN stations that can be exploited by an Evil Twin attack?

  • Weak passwords used for WPA encryption
  • Insufficient encryption protocols used for data transmission
  • Automatic reconnection to any previously used SSID (correct)
  • Lack of secure authentication protocols for wireless access
