bots
B.
DDoS
C.
Trojan horses
D.
viruses
Explanation:
Of the available choices, a Distributed Denial of Service (DDoS) attack is least likely to be considered a form of
malware. Malware, which is a term formed from the combination of the words malicious and software, is
unwanted software that is specifically designed to be malicious. Malware can damage or disrupt systems, steal
information from a user, or perform other unwanted and malicious actions.
A DDoS attack is a coordinated Denial of Service (DoS) attack that uses multiple attackers to target a single
host. For example, a large number of zombie hosts in a botnet could flood a target device with packets.
Because the flood of packets originates from multiple hosts and typically targets public services, such as the
web service, the target device might not detect the attack. If enough packets are sent to the target device within
a short period of time, the target will be unable to respond to legitimate packets because it is waiting for a
response to each of the requests originated by the attacker.Bots are forms of malware. A bot is a type of automated software that can be used as a remote command and
control tool to exploit a compromised system for malicious purposes. For example, a botnet is a network of bots
on compromised systems that can be used to carry out coordinated attacks, such as a DDoS attack.
Viruses are forms of malware. A virus is a type of software that can make copies of itself and inject them into
other software. Viruses can therefore spread across systems and networks. The level of damage that can be
inflicted by a virus ranges from annoyances to destruction of data.
Trojan horses are forms of malware. A Trojan horse is a malicious program that entices the user to execute it
by appearing to be a legitimate application. Trojan horses can be used to annoy users, steal information,
destroy data, or install back doors.Cisco: What Is the Difference: Viruses, Worms, Trojans, and Bots?
