In the last lecture, we saw different types of denial of service or distributed denial of service attacks
in this lecture.
We will see what is a botnet?
A botnet refers to a group of computers which have been infected by malware and have come under the
control of a malicious actor or hacker.
The term botnet is a portmanteau from the words robot network, and each infected device is called the
bot.
Mortensen's can be designed to accomplish illegal or malicious tasks, including sending spam, stealing
data, ransomware, fraudulently clicking on ads are distributed in a service that its leaders attacks.
While some malware, such as ransomware, will have a direct impact on the owner of the device, the
botnet malware can have different levels of visibility.
Some malware is designed to take control of the device, while other malware then silently as a background
process while waiting silently for the instructions from the attacker or bot handler, self-propagating
botnet recruit additional bots through a variety of different channels.
Pathways for infection include the exploitation of website vulnerabilities, Trojan horse malware and
cracking big authentication to gain remote access once access has been obtained.
All of these methods for infection result in the installation of the malware on the target device,
allowing remote control by the operator of the botnet.
Once the device is infected, it may attempt to self-propagating the malware by recruiting other hardware
devices in the surrounding network.
While it's invisible to pinpoint the exact numbers of the bots in a particular botnet, estimations
for total number of partners in a sophisticated botnet have ranged in size from a few thousand to greater
than a million.
While Bawdiness created reasons for using a botnet ranges from activism to state sponsored disruption,
with many attacks being carried, simply for profit or characteristics of a botnet is the ability to
receive updated instructions from the bot handler.
The ability to communicate with each board in the network allows the attacker to alternate attack vectors,
genes, a targeted IP address, terminate an attack and other customized actions.
Botnet DNS Mavity.
But the control structures can be broken down into Pugin categories, the client server botnet model
and the peer to peer.
But this is all for this lecture.
In next lecture, we will see how to create a spectacle on a system or a targeted website.
