One of the primary vulnerabilities in WPA2 is the Key Reinstallation Attack, also known as KRACK, which allows attackers to intercept and decrypt wireless communications. This attack exploits weaknesses in the WPA2 protocol, enabling hackers to access sensitive data such as passwords and credit card information.
Another vulnerability in WPA2 is the brute force attack, where an attacker attempts to guess the Wi-Fi password by systematically checking all possible combinations until the correct one is found. With modern computing power, this type of attack can be successful, especially if the Wi-Fi password is not strong enough.
WPA3 addresses these vulnerabilities by introducing several security enhancements. One such enhancement is the Simultaneous Authentication of Equals (SAE) handshake, which provides better protection against brute force attacks. Additionally, WPA3 uses stronger encryption algorithms, making it more difficult for attackers to eavesdrop on wireless communications.
