![]() ![]() Once the installation is complete, you can then run it with: īe warned, running a full scan can take a while as chkrootkit examines running processes and the Linux kernel. Next, open the Linux Terminal and install the utility by running: ![]() To get started, save and close any running apps. The good news is that there’s an excellent Linux utility called ‘chkrootkit’, which can detect most types. Encryption also can’t help, as some rootkits contain keyloggers to record your passphrase as you type it in. This means they can’t be detected by regular antivirus and can even survive you wiping your system. These are a very dangerous type of malware that lurk in unusual places on your system such as your boot partition or system firmware. 3 – Detect and Remove RootkitsĮven a properly encrypted system isn’t vulnerable to a rootkit. ![]() Remember that formatting the drive will erase any data already on it. Simply open the utility, choose ‘Format Partition’ and check the option ‘Password Protect Volume (LUKS).’ Each time the disk is inserted, you’ll need to enter this passphrase to view and edit the disk contents. In Ubuntu, you can also use the built-in Disk Utility to encrypt drives using LUKS. If any of the listed drives contain the string ‘crypt’, then they’ve been encrypted.If your system isn’t encrypted, back up your personal files before attempting a fresh install. If you aren’t sure if you chose this option during installation, on Debian-based systems like Ubuntu you can open Terminal and run the following command to check: The bad news is that Linux doesn’t support encrypting your operating system in place. This means if your Linux device is powered off and falls into the wrong hands, bad actors won’t be able to access your personal data, provided you’ve used a strong enough password. This is usually a matter of checking the relevant box and setting a strong passphrase. ![]() Most versions of Linux support encrypting the hard drive during installation via LUKS (Linux Unified Key Setup). Alternatively download and install the Linux version of Brave Browser, which has a built-in ad blocker. We recommend using either AdBlock Plus or uBlock Origin. Most ad-blockers are cross-platform so will have no trouble running in your Linux web browser. This will not only protect you from annoying banner ads and videos, but these blocklists can also help block harmful links that lead to malware. If any site component is flagged as advertising material, the ad blocker stops it from loading and appearing on the user end. If you install an ad-blocker, whenever a site loads, it will check the domain names of any elements loading on the web page against massive ‘blocklists’. Part of the reason for this is that many individuals and organizations have started using Linux machines in order to protect their privacy, making the OS a more tempting target.Īd-blockers work as browser ‘extensions’ – add-ons, which you can download directly into your web browser to change its performance in some way. 1 – Use an ad-blocker browser extensionĪccording to a report cited by Linux Insider, malware threats to Linux increased by 50% to 1.9 million in the past year. In this tutorial, you’ll learn 7 quick steps you can take to hugely boost your privacy & security whilst using Linux. Still, the ‘threat landscape’ is constantly shifting and even Linux users can’t afford to feel smug. Simply by using Linux, you’re also protected from most forms of malware, given that hackers tend to write malicious code that will run only on more popular operating systems like Microsoft Windows and macOS. Using open-source software means the code is freely available to be examined and updated by developers, making it far less likely to contain security bugs or hidden ‘backdoors’ to spy on you. If you’ve already made the decision to switch to an open-source Linux operating system like Ubuntu, you’re already well on your way to protecting your privacy. ![]()
