What are Bots, Botnets and Zombies in cyber Security?

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.

Although taking over one computer is useful, the real value to a criminal comes from collecting huge numbers of zombie computers and networking them so they can all be controlled at once to perform large-scale malicious acts. This type of network is known as a "botnet".

 

 

 

How Do Botnets Work?

Botnets have been one of the most common methods of malware deployment for the past decade, infecting hundreds of millions of computers. As botnets infect new technologies, such as Internet of Things (IoT) devices in homes, public spaces, and secure areas, compromised systems can put even more unsuspecting users at risk.

 

They perform large operations while remaining small.

Most people would be shocked to learn that the spam they're receiving is coming from thousands or even millions of computers just like their own. The real owners of those computers can still use them, and are probably totally unaware that anything is wrong, except perhaps that their computer sometimes seems slow. Most botnets have an extremely small footprint, meaning they bog your system down or use a lot of system resources, so it can be difficult to recognize when your machine is being used by a criminal for malicious purposes. They also typically have the ability to mask themselves, so they can perform large-scale attacks without getting noticed.

it only takes minutes for an unprotected, internet-connected computer or another device to be infected with malicious software and turned into a bot, underscoring the critical need for every computer and smartphone user to have up-to-date internet security software on all their devices and to always change factory default usernames and passwords.
