WPA and WPA2 introduced stronger encryption methods with TKIP and AES, respectively. However, they are not foolproof. Red Teamers often exploit weak passwords through dictionary attacks on the four-way handshake process using tools like Hashcat and John the Ripper. Additionally, the KRACK vulnerability in WPA2 exposes networks to potential traffic decryption and injection, highlighting the need for robust password policies and timely updates.
WPA3 represents the latest in Wi-Fi security, incorporating features like SAE (Simultaneous Authentication of Equals) for enhanced password protection and forward secrecy. Despite these advancements, WPA3 is not immune to sophisticated attacks such as side-channel and downgrade attacks. Effective defense against these exploits requires continuous security assessments, the use of complex passwords, and regular protocol updates, underscoring the critical role of Red Teamers in fortifying wireless network security.
