If you’re from a non-technical background let alone a software-oriented background, then it would prove to be difficult for you to understand something like botnet. in this article about Botnet, we aim at making you aware of the various aspects related to Botnet and its application in the present world. We hope you find this article of use.
Botnet defines the combined threat of cybercrime that a group of devices faces together. The common malware faced can be by personal computers, servers, mobile devices, and IoT – the internet of things devices. The threat is usually hidden from these users so they remain absolutely unsuspicious about the whole scenario until their actual data seems attacked. The infected devices are further controlled by cybercriminals for various incentives, usually harmful.
The main functionality of a botnet is to send spam emails, generate malicious and untraceable traffic for some DDoS – distributed denial of service attacks, and even engage in click fraud. The person responsible for initiating the attack can control the botnet using command and control (C&C) software. The basic principle behind the working of the botnet is the breach of basic security protocols and the authority of infected devices being given to a third unknown party. HTTP (hypertext transfer protocol) and IRC (internet relay chat) serve as standard network protocols for the same.
Botnet has evolved over the years to evade detection and suspicion from cyber authorities and to make the anti-tracing capabilities even more enhanced.
Cheap internet-capable devices are always prone to such botnet attacks majorly because of a lack of proper security protocols. Keeping weak or factory default passwords can also owe to botnet attacks because of being easily compromised. Sometimes the clients are unable to change or view their passwords which leaves them amidst the digital traffic, open to such attacks.in a more generic way, IoT devices always are at higher risk of getting hacked because they offer a seemingly large surface for botnets to spread on.
Typically one would evade the botnet attacks by simply focusing and bettering the C&C software of the device but these attacks have become more sophisticated and it has become more and more tedious to find the communicators, the cyber security is manned not only in terms of C&C but also through identification and removal of botnet malware at the source device itself.in the case of ad frauds, disturbing the monetization chain proves to be the most fruitful, rather than aiming at improving the technical infrastructures.
The botnet herder community has unparalleled competition in terms of who has the most wide spread bots, the highest overall bandwidth, which herder has the most amount of high quality and secure infected machines like government systems.
A hacker first buys or preferable builds an exploit kit to start infecting devices. After the bot has entered the infected device, the bot instructs the system to connect to a particular command and control (C&C) server which is managed by the cybercriminal. The botmaster then uses the different bots to receive sensitive data like online credentials and may even sell these credentials to online profit organizations or individuals.
The revenue generated with the data depends solely on the quality and precision with which the bot has performed the given task. A bot becomes more and more capable as it scans and breaches newer, more vulnerable systems in its vicinity. Sometimes it’s also possible to create and embed bots that are temporary and automatically self-destruct after the mission has been accomplished.
After reading this article we hope that you have a better understanding of botnet and the various aspects related to its application in the present world.
