The botnet can be troublesome when using your technology for work or gaming. It can affect your device’s systems and even invade your privacy. This post will explain what botnet is, and show you how to avoid it.
What is a botnet?
The term “botnet” is a combination of the words “bot” and “network”. When a device becomes infiltrated by software distributed by malware, it will create a “bot program” for each compromised device. Bot programs are malware that can infect computers to perform commands under the remote control of an attacker.
Nowadays, cybercriminals are increasingly using botnets as a commodity for hire for various purposes. They use botnets to spread malware such as viruses to take control of your computer/software. This control allows them to have unlimited access to your personal information, including passwords and account login information. Therefore, the term often has a negative or malicious connotation.
Common botnet behavior
- Email spam
Spam botnets are massive. Mostly, they serve to send spam including malware from each roamer in the form of spam emails. In addition, in order to recruit more computers to the botnet, they are used to spread bot programs. These type of emails are usually disguised as messages from every day people, or advertisers. They can be quite annoying or worse, malicious.
- DDoS attacks
The DDoS attack is an attack on specific websites, servers, and networks by using massive botnets. This can overload the network of the target website or target server with requests, making it inaccessible to its target users.
- Financial breaches
Financial breaches are botnets dedicated to stealing money and credit card information directly from businesses. Such botnets can often embezzle large amounts of money in a short time.
- Targeted Attacks
Targeted attacks tend to be launched by smaller botnets with the primary goal of disrupting specific high-value systems of an organization. These intrusions are extremely dangerous to companies because attackers will specifically target their most valuable assets.
How to identify botnets
