Which of the following is used by attackers to record everything a person types, including
usernames, passwords, and account information?

A.
Packet sniffing

B.
Keystroke logging

C.
Spoofing

D.
Wiretapping

Explanation:
Keystroke logging is used by attackers to record everything a person types,
including usernames, passwords, and account information. Keystroke logging is a method of
logging and recording user keystrokes. It can be performed with software or hardware devices.
Keystroke logging devices can record everything a person types using his keyboard, such as to
measure employee’s productivity on certain clerical tasks. These types of devices can also be
on voice calls. Eavesdropping is the process of listening in on private conversations. It also

that makes a transmission appear to have come from an authentic source by forging the IP
address, email address, caller ID, etc. In IP spoofing, a hacker modifies packet headers by using
someone else’s IP address to hide his identity. However, spoofing cannot be used while surfing
the Internet, chatting on-line, etc. because forging the source IP address causes the responses to
travel across a network. The software used for packet sniffing is known as sniffers. There are
many packet-sniffing programs that are available on the Internet. Some of these are unauthorized,
which can be harmful for a network’s security.
