Technically, Botnet is the collection of ‘Internet-connected programs’ through which other similar programs can be commanded to perform certain tasks. As mentioned above, these programs are used for malicious purposes. Criminals first infect the computers and transform them into malicious robots, also known as zombies that perform automated tasks over the Internet, without the knowledge of the owner. Likewise, a loop is created and cybercriminals continue using the bots to inject malicious software into large number of computers using the Internet network.
Through the medium of these malicious robots, criminals can send spam email messages, attack computers and servers, spread viruses, and commit various other kinds of online crimes. The main problem with Botnet is that, if your computer has been transformed into Botnet, you won’t be able to recognize it and unknowingly you will end up helping the criminals.
