Cyber attacks are more common than ever as technology is increasingly integrated into our everyday lives. Bots and botnets are a major trigger for these risks. These malicious automation tools are capable of causing chaos and destruction for businesses and online activities.
Botnet detection is now a major concern for the cybersecurity industry. Many companies do not realize how serious this threat is. Cybercrime will cost $8 trillion USD by 2023, according to a Cybersecurity Ventures report.
These attacks affect all businesses, small and large. It is important that the business community raises awareness about this issue. Companies can block botnets and stay alert by adopting the right knowledge and measures.
Understanding Botnets. What are they?
Let’s review briefly what bots and Botnets are before we get into the best practices of botnet detection. We will examine how they operate, what they are capable of, and how we can deal with them.
What is a Bot?
Bots, or “robots,” are software programs that automate tasks on the Internet. Bots are used for a variety of purposes, such as web crawling and indexing.
When a bot performs harmful activities, however, it poses a security threat. Hackers can create malicious codes that mimic human behavior and perform repetitive tasks. They may watch YouTube videos, engage in social media, or click on ads to increase their numbers.
What is a Botnet?
A botnet is a collection of bots that are working together for a common goal. A botnet is basically a group of infected computers controlled by a single “botmaster” or attacker.
When malware is installed across a large number of computers, smartphones or other Internet of Things devices (IoT), a botnet is created. IoT refers to all digital devices (smartwatches, smarthome devices and more) that are connected to the internet. They can share information or trade data to make life easier.
Infected devices can also be called “zombie” devices or “zombies”. The infected devices can be used to create a botnet or “zombie armies”. Each bot can affect thousands, making the botnet more powerful and dangerous.
We can now imagine the damage that the “zombie” army can do if it is not stopped.
What is the botnet?
Botnets are autonomous until they connect to a C&C server. The botnet and the C&C server are controlled by one person known as “botherder” or “botmaster”. The botmaster directs all bots to perform attacks or engage in other malicious activities. This person is acting remotely by sending updates and manipulating the actions of infected machines.
The botnet may not display any malicious behavior until it is commanded to do so. Owners of affected devices usually are unaware of this. A botnet can harm your business in two different ways.
It can first infect one device or more in your network, and then use them as part of a Botnet. You may not even be aware that your device has been used for malicious or fraudulent online activities.
It can also use its combined strength to attack your business. DDoS attacks can be used to disrupt your business. A large number of bots could flood a server with traffic at the same time, overloading its capacity, and cause it to crash. This can cause significant downtime and loss of revenue (and real traffic).
It is important to understand how botnets work and what their impact can be in order to prevent and detect attacks. We will examine the types of botnets that are most common and their operation in the next section.
Botnets: types and attacks
There are many different types of botnets, each designed to perform specific malicious activities. Here are the most common botnets, and their associated attacks.
DDoS Botnets: Distributed denial of service (DDoS), botnets, are designed for DDoS attacks. These attacks are a result of overloading a website, server, or network with traffic. This can cause the site to crash or be inaccessible. Cybercriminals can use DDoS attacks as a way to extort businesses for money or as a distraction from other attacks such as malware or data theft. Click bots: Click Bots are used to commit Click Fraud or Ad Fraud. This type of fraud involves clicking on advertisements to generate revenue for an attacker. Click bots are also capable of engaging with ads from competitors or generating fake clicks. In this way, advertisers waste their advertising budget and get inaccurate traffic statistics. Google Ads, the platform used by advertisers, and even Google itself, have tried different techniques for botnet detection to reduce them. Click Bots, however, use advanced algorithms that make them more difficult to detect. Scraper bots are used to scrape content and steal personal information. Some botnets can be used to scrape information from websites, or steal personal data such as credit card numbers or login credentials. Information stolen can be sold on the dark net or used to steal identities. Scalper Bots: Attacks using scaler botnets are designed to purchase large quantities at high demand. Botmasters aim to resell the products at a higher price in order to make a profit. Botnet attacks of this type are often used to attack tickets, events, retail stores, ecommerce, and limited-edition items. Spam bots: These bots send spam emails or phishing messages. Phishing emails trick the recipient into divulging sensitive information or installing malware on their device. Spam bots are powerful tools for cybercriminals, as they can send millions of emails within a short time.
How to stop botnets from damaging your business
After we’ve covered the various types of botnets, and the attacks they cause, it’s now time to concentrate on the most crucial part: how to protect your company from botnets. It is possible to prevent botnet attacks, even though they can be devastating. Here are some tips to protect your business against botnets.
Good security practices
Good security practices are one of the best ways for your business to be protected from botnet attacks. It is important to protect your network infrastructure, software, and devices against vulnerabilities. Make sure you have an antivirus and firewall in place, and keep your operating system and software up to date with the latest patches.
Use 2FA
Two-factor authentication (2FA), also known as two-factor security, is an extra layer of protection that prevents botnet malware from breaking in to devices and accounts when a password is compromised. You will need to enter an one-time code, or confirm your login attempts, to use 2FA. This makes it harder for hackers to access your accounts.
Regularly train your staff and users on cybersecurity.
Cybersecurity education is crucial to preventing botnets. Your employees should be educated on how to recognize phishing emails and suspicious links, attachments, or attachments. Regularly remind your employees of cybersecurity best practices and set up policies to ensure safe internet use.
Do not open attachments or links in suspicious emails
Botnet malware can be distributed by email as attachments or via links. Even if the email appears to come from a trusted source, you should not click any links or open any attachments. Before opening attachments, scan them with an antivirus program or hover your mouse over the link and check the URL.
Run regular ad and network traffic analyses
Botnets generate large amounts of traffic on the network, which may indicate their activity. Use a network monitor (Google Analytics is also useful) to detect any abnormal network activity. Also, regularly monitor the ad traffic in order to identify any suspicious activity.
Update your operating system
Botnets are often designed to exploit vulnerabilities in operating system. Install the latest security patches on all of your devices. These updates contain security patches which fix vulnerabilities that botnets can exploit.
Following these best practices will help you prevent botnets damaging your business. Remember that botnets can cause a lot of damage to your business. It is important to be proactive in protecting it.
