Final answer:
WPA2, a secure Wi-Fi security protocol, is susceptible to attacks such as Key Reinstallation Attacks (KRACK), dictionary attacks on weak passwords, and man-in-the-middle (MitM) attacks.
Step-by-step explanation:
The question refers to the security vulnerabilities associated with the Wi-Fi Protected Access 2 (WPA2) protocol. WPA2 has been considered as the secure standard for Wi-Fi security, but it is susceptible to certain types of attacks. One known form of attack is the Key Reinstallation Attack (KRACK), where attackers take advantage of a flaw in the WPA2 handshake process to decrypt network traffic. Another is a dictionary attack on weak pre-shared key (PSK) passwords. More sophisticated attacks may involve man-in-the-middle (MitM) tactics to intercept and manipulate traffic. It's important for network administrators to use strong, complex passwords and stay aware of updates and patches to mitigate these vulnerabilities.
