During a red team engagement, an ethical hacker is tasked with testing the security measures...

bettercap is a tool that can perform session hijacking attacks on wireless networks, among other network security and penetration testing tasks. bettercap can capture and manipulate network traffic, perform man-in-the-middle attacks, spoof and sniff protocols, inject custom payloads, and more1.

bettercap can perform session hijacking attacks on wireless networks that use the WPA-PSK security protocol by exploiting the four-way handshake process that occurs when a client connects to a wireless access point. The four-way handshake is used to establish a shared encryption key between the client and the access point, based on the pre-shared key (PSK) that is configured on both devices. However, the four-way handshake also exposes some information that can be used to crack the PSK offline, such as the nonce values, the MAC addresses, and the message integrity code (MIC) of the packets2.

bettercap can capture the four-way handshake packets using its Wi-Fi module and save them in a file. The file can then be fed to a tool like Hashcat or Aircrack-ng to crack the PSK using brute force or dictionary attacks. Once the PSK is obtained, bettercap can use it to decrypt the wireless traffic and perform session hijacking attacks on the clients connected to the access point3.

Therefore, bettercap is an appropriate tool to carry out a session hijacking attack on a wireless network that uses the WPA-PSK security protocol.
