Topic: WLAN Attacks and Mitigation
Attack #1: Evil Twin Access Point
Description:
An attacker creates a fake Wi-Fi access point with a name similar to a legitimate
network. Users may unknowingly connect to the attacker-controlled network, which can
enable the attacker to capture sensitive data or launch further attacks.
Mitigation:
User Education: Educate users about the risks of connecting to unknown or open Wi-Fi
networks. Emphasize the importance of verifying network names and using reliable
VPN solutions for enhanced security.
Wireless Intrusion Prevention Systems : Implement WIPS tools that can detect and
locate rogue access points, actively blocking unauthorized wireless networks.
Attack #2: Deauthentication Attack
Description:
The attacker sends crafted deauthentication frames to wireless clients, forcing them to
disconnect from a legitimate access point. This can disrupt network services or force
clients to reconnect to a rogue access point under the attacker's control.
Mitigation:
Modern Wi-Fi Standards: Use devices that support WPA3, which offers better protection
against deauthentication attacks than older standards like WPA2.
Intrusion Detection: Utilize WIPS that can detect and alert administrators to potential
deauthentication attacks.
Attack #3: WPA/WPA2/WPA3 Cracking
Description:
This attack exploits vulnerabilities in Wi-Fi encryption protocols to decrypt wireless traffic
or modify data packets. Attackers can intercept and potentially obtain sensitive
information like passwords or credit card details.
Mitigation:
Software Updates: Ensure all wireless devices (access points, routers, and clients) are
running the latest firmware and security patches released by manufacturers.
Strong Passwords: Use strong and unique passwords for your Wi-Fi network, avoiding
easily-guessed phrases or default settings.
