A botnet is a collection of internet-connected devices, typically compromised computers and other electronic devices, which are used to send malicious messages or perform malicious activities. Botnets can be used to send spam, launch distributed denial-of-service (DDoS) attacks, infect computers with malware, steal data, and perform other malicious activities.

Botnets are created by malicious actors, typically referred to as “bot herders” or “bot masters”, who use sophisticated techniques to infect computers and other devices with malicious software, known as “bots”. These bots are then used to control the infected devices remotely and can be used to send malicious messages or perform other malicious activities.

Botnets have become increasingly common due to the ease with which malicious actors can use them to launch large-scale cyber-attacks. For example, botnets can be used to launch DDoS attacks, which are used to overwhelm a website or other online system with a large number of requests, making it inaccessible. Botnets can also be used to steal data, spread malicious software, and perform other malicious activities.

As a result, it is important to be aware of the dangers posed by botnets and take steps to protect your devices from being compromised. This can include using secure passwords, using up-to-date antivirus and anti-malware software, and avoiding clicking on suspicious links.
