A
Virus
B
Trojan Horse
C
Botnet
D
Smishing
E
Dumpster Diving
Explanation: 

Detailed explanation-1: -A botnet, which stands for a network of bots, is a distributed system of compromised computers infected with the same type of malware that allows the attacker to use the consolidated pool of computing resources to launch large-scale cyber attacks.

Detailed explanation-2: -A DDoS attack, however, uses multiple connected devices-often executed by botnets or, on occasion, by individuals who have coordinated their activity.

Detailed explanation-3: -These collections of compromised systems are known as botnets. DDoS tools like Stacheldraht still use classic DoS attack methods centered on IP spoofing and amplification like smurf attacks and fraggle attacks (types of bandwidth consumption attacks).

Detailed explanation-4: -A bot, in this case, is a device infected by malicious code, which then becomes part of a network, or net, of infected machines all controlled by a single attacker or attack group. A bot is sometimes called a zombie, and a botnet is sometimes referred to as a zombie army.

Detailed explanation-5: -DDoS. A distributed denial-of-service (DDoS) attack is an attack in which multiple compromised computer systems attack a target, such as a server, website or other network resource, and cause a denial of service for users of the targeted resource.
