What are Botnets and How Can You Protect Yourself?

A botnet is a network of hacked devices that includes computers, smartphones, mobiles, laptops, and other internet devices. Hackers use malware and viruses to infiltrate, infect, and take control of the device. Once hacked and controlled, each device is called a bot or a zombie because it runs mindlessly without the will of its owner. When a large group of bots connects, it becomes an army of zombies or a botnet.

Cybercriminals control Botnets via a remote control. They use it to launch large-scale cyberattacks on multiple targets, flooding websites with DDoS attacks, and steal private details of the users. They use your device’s energy to run their expensive business without spending a penny on maintaining huge infrastructures and power plants. Along with this, they launch crypto scams via your device network and trap more users.

How can You Protect Yourself From Botnets?

Botnets are the deadliest cyberattacks that affect individuals and organizations in the worst possible way. They take a toll financially on people, derailing and disrupting business processes. But you can prevent botnets from affecting you if you practice safety. Here are some effective tips that can protect you from the attacks of botnets:

Keep Your Device Up-to-Date

You have to keep your device up-to-date. That means you need to download software updates as soon as they are made available. Hackers love old and outdated software programs on your device. Outdated programs develop vulnerabilities and security weaknesses. Hackers can exploit these security gaps to inject malware into your system and hijack all the data inside it. New updates fix old security gaps that develop over time and make your device immune to cyberattacks.

Use Strong, Unique Passwords

Create long, strong, and unique passwords to protect your device, apps, and accounts. Use a combination of letters, numbers, and special characters to compose unique passwords. Also, do not use a single password to protect multiple accounts and access. Hackers won’t be able to breach your online security if you have one of your passwords. Do not use your name, home, or office address to create your password. They are weak and easily guessable keys that cybercriminals can extract using automated tools.

Turn on Two-Factor Authentication (2FA)

Passwords are not enough to protect your device and access points. You should use two-factor authentication to double down on your device security. 2FA uses email, call, and SMS to authenticate that it is you who is trying to log in to the account or device. In this process, you get a code or OTP on the registered email or mobile no. You type this code in the verification window, and if the code is right, you get access. With 2FA, if someone got your login details, they won’t be able to access your account without the verification code. So, you become safer and secure from cyberattacks.

Be Suspicious of Links and Attachments

Hackers attack malicious links and URLs in emails, messages, and notifications. They give attractive offers and emergency alerts in the messages, such as “you won a lottery,” or “bank withdrawal alert,” to trick the users. Along with this, they attach a link in the message and ask the user to click the link to fix the issue or claim the offers. Users often click the links and URLs out of curiosity to know more. But as soon as the link is clicked, it redirects to a malicious website that downloads malware on the device.

Hence, it is highly important to double-check the links and URLs before you click them. If they are coming from an unknown or suspicious source, then they can be baits used by black hats to trap you. It is highly important that you avoid clicking them at all costs to protect your online privacy and security.

Install Reliable Security Software

It is highly recommended that you use an advanced antivirus software on your device to protect it from cyberattacks, malware infections, and security breaches. Antivirus software monitors your device operations in real-time to make sure no malware or virus infiltrates or runs in the background. It comes with advanced features like heuristic and behavior analysis that scan every program and software for its activities. If any of the programs behave suspiciously, use antivirus software and sandbox it for further analysis. It can detect and remove the affected program from your PC instantly. All you need to do is keep your security software up-to-date all the time.

Avoid Public WiFi

If you are using public internet services or WiFi services, you should use VPNs on your device. Hackers use public WiFi networks to lure users and infiltrate their devices. They set up fake networks using the same name with slight spelling variations at public places such as restaurants, malls, colleges, and hospitals. Users often connect to these free-to-use internet networks to do their online tasks. As soon as they connect with them, hackers get their device details and inject malware into them. With this infiltration, they hack the device and steal all the private information from it. Hence, it is highly recommended that you use a VPN whenever you connect to a WiFi or completely avoid it.

Watch Your Device Performance

Your PC’s performance says a lot about its security conditions. If it is now working well and your normal operations are taking too long or glitches are frequently coming up, then there is something wrong with its internal workings. The potential cause can be the existence of a virus or malware that is running in the background and using too many system resources. As a result of this infiltration, your device’s performance becomes sluggish. If you are experiencing slow system speed, then do not take it lightly. It is a strong indication that there is a malicious program on your PC.

Do Not Allow Permissions

Monitor app permissions in your Internet of Things. Whenever you download and install an app or software on your device, it asks you for a lot of permissions, such as contacts, media, map, and microphone. So, at the time of installation, do not allow all the permissions to all the apps. Go and check into the permissions tab on your device, and what permissions you have allowed. Disallow unnecessary permissions on your phone. They put your device at risk of privacy loss and security breaches. Whenever you install an app, make sure you allow it only the most necessary permissions.

Final Thoughts

As the internet technology is becoming a daily staple in our lives, it is highly important that we take special care of our Internet of Things. Cybercriminals are lurking everywhere on the web, and they leave no chance to take charge of you if you leave a security gap open for them. You have to stay alert and active while browsing online. Use best safety practices to stay one step ahead of black hats and keep your device security intact.
