Kismet

C.
AirSnort

D.
Cain

Explanation:

AirSnort is a Linux-based WLAN WEP cracking tool that recovers encryption keys. AirSnort
operates by passively monitoring transmissions. It uses Ciphertext Only Attack and captures
approximately 5 to 10 million packets to decrypt the WEP keys.
Answer option B is incorrect. Kismet is a Linux-based 802.11 wireless network sniffer and intrusion
detection system. It can work with any wireless card that supports raw monitoring (rfmon) mode.
Kismet can sniff 802.11b, 802.11a, 802.11g, and 802.11n traffic. Kismet can be used for the
following tasks:
To identify networks by passively collecting packets
To detect standard named networks
To detect masked networks
To collect the presence of non-beaconing networks via data traffic
Answer option D is incorrect. Cain is a multipurpose tool that can be used to perform many tasks
such as Windows password cracking, Windows enumeration, and VoIP session sniffing. This
password cracking program can perform the following types of password cracking attacks:

Dictionary attack
Brute force attack
Rainbow attack
Hybrid attack
Answer option A is incorrect. PsPasswd is a tool that helps Network Administrators change an
account password on the local or remote system. The command syntax of PsPasswd is as follows:
pspasswd [\\computer[,computer[,..] | @file [-u user [-p psswd]] Username [NewPassword]
