How botnets are created
One may wonder what botnet traffic is, and what it can do. A botnet involves a group or network of these ‘zombie computers’ working together to perform a similar function. Numerous bots or machines affected by bots might behave like zombies on a variety of server responses. Commonly, the attacker looks for instances of vulnerability on a victim or target. From here they target to install the software on the victim’s computer. Popularly, people use spam emails to send bots to people computers. They then trick the victim into clicking a call-to-action button which initiates the entire attack. Other scammers send spam emails containing malware and Trojans.
When a bot is installed on a victim’s computer, they now use the PC’s network availability to carry out their attacks. For instance, they contact their domain server where commands and instructions come in. The person behind the botnet attack uses the command-and-control (C&C) server to collect any information they need from the infected machines.
A website attacker who is operating the botnet scheme has a client program which contains the set of instructions for the bots. These tasks can involve the collection of data, browser execution (passwords, credit cards, logins, and cache), controlling a computer or even using the victim’s computer hardware. One flexibility aspect of botnets includes the ability to control some single or multiple bots.
Effects of botnets
Botnets compromise the internet security of numerous websites. Information and data security become affected by these botnet attacks. When a botnet installs malware on a user’s PC, this information is no longer under the control of the user. People who store sensitive information like financial accounts, banking information, login credentials, etc.; on an infected system risk losing to the attackers.
Attackers can also attack as many computers as possible for their reasons. For instance, botnet attacks have executed denial of service attacks on networks. DDoS attacks involve sending many web requests to a server, slowing down its efficiency due to scheduling. In extreme cases, people bring down an entire website with these techniques.
