COMPUTER FUNDAMENTALS

Detailed explanation-1: -A botnet (short for “robot network”) is a network of computers infected by malware that are under the control of a single attacking party, known as the “bot-herder.” Each individual machine under the control of the bot-herder is known as a bot.

Detailed explanation-2: -A bot, short for “robot", is a type of software application or script that performs automated tasks on command. Bad bots perform malicious tasks that allow an attacker to remotely take control over an affected computer. Once infected, these machines may also be referred to as zombies.

Detailed explanation-3: -These computers are often called “zombies.” Botnets can be used for anything from phishing to DoS (denial-of-service) attacks and spam propagation. When the authorities try to trace the attack back to the culprit, they are led back to a zombie computer and an unknowing victim of a bot.

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: -The criminals who purchase access to botnets then go on to use the infected computers for various crimes, including theft of personal or financial information, the dissemination of spam, for use as proxies to conceal other crimes, or in distributed denial of service (DDoS) attacks on computers or networks.
