Botnet can be used to do Distributed Denial-of-Service (DDoS) attacks, steal credentials or any information, send spam, and allow the invaders to access the device and its connection. Botnets are build to produce, automate, and speed up a hacker’s skill to bring out bigger attacks.
One individual or even a hacker of a small team can only carry out so many activities on their local devices. But, at a lesser price and a bit of time devoted, they can obtain lots of extra machines to leverage for further effective operations.
A bot herder chiefs a joint of hijacked devices with commands that are remote. When they’ve gathered the bots, a herder uses command programming to initiate their resulting actions.
Basic stages of building a botnet
Stage 1 :
The Exposure starts with hackers finding a weakness in an internet site, apps, or by the behavior of humans. The aim is to establish the user up for unknowingly showing an infection of malware. You’ll regularly see hackers exploit security problems in software or internet sites or send the malware over emails and further online messages.
Stage 2:
The device will get compromise when the user gets infected with botnet malware. Users get attack via social engineering to download a virus. Other attackers may be more destructive by using a drive-by download upon visiting a site that is infect.
Stage 3:
The last stage will start by taking control of each system or device once the hacker is ready. The attacker arranges all of the machines that are infect up into a bot network that they can remotely manage. The cybercriminal will search to infect and control many computers. The cybercriminal can then turn into the dominant level guy of a big zombie network.
Types of Botnets Attacks
The DDoS attack is an attack in which the invader sends a great number of requests to the victim web server to stop the server from working appropriately. Zombie computers are task with crowd websites and further online services, resulting in them being down for some while.
Phishing schemes copy reliable people and organizations for trapping them out of their information or data. This includes a large-scale spam movement meant to snip user account data or info like banking logins, personal information, and credentials.
Brute force attacks run programs designed to crack accounts in the web by force. Dictionary attacks and credential stuffing are used to exploit passwords of users that are weak and access their information.
