What is Keylogging? Tips on How to Detect and Prevent Keylogging

What is Keylogging


With each passing year, hackers develop more sophisticated tools and programs to stay ahead of the curve and deal a lot of headaches to cybersecurity experts. But, one tool that has been around for decades and is still dangerous as it was when it was invented is a keylogger. 

Keyloggers are notorious for their ability to collect all of your personal data without you even noticing it. They work quietly in the background, monitoring every word you type without giving any sign of their existence.

So, what’s keylogging, and how harmful can it be? More importantly, are there any reliable tips on how to detect keylogging and prevent keylogging attacks? In this guide, we’ll share the best ways to ensure keylogging protection and discuss valuable pointers on how to detect keylogging software.

What is Keylogging?

Before we talk about more complex aspects of keylogging, let’s start with the basics, beginning with the keylogging definition. If you’re wondering what does keylogging mean, this term can actually refer to two things. 

Firstly, keylogging can refer to keystroke logging. This is the activity of keeping a detailed record of every key pressed on a keyboard. Besides that, it can also describe keylogger tools. These are devices or programs that are used to record these keystrokes. 

In their nature, keyloggers can be used for legitimate research purposes. But, we mostly associate them with illegal or harmful activities in which malicious hackers exploit unsuspecting targets for profit.

How Does Keylogging Work?

Keyloggers can work differently depending on the way they are installed on the target device and the way they collect data. There are two types of keyloggers. These are:

  • Hardware Keyloggers - such keyloggers can’t be detected by antivirus and antimalware software, as they aren’t installed on the computer. Instead, they use their own internal memory to store information. Hardware keyloggers are more challenging to set up as they require physical access to the target, for example, installing a fake keyboard overlay on an ATM.
  • Software Keyloggers - these types of keyloggers are much more common as they are more discrete and can easily hide in your system. These keyloggers can reach your device on a Kernel level, on an API level, or even on a screen and browser level. 

With this in mind, there are two main ways a keylogger can get on your device. A hardware keylogger has to be physically installed, while software keyloggers can infect your device remotely. Because of this, software keyloggers are often associated with malware. To be more precise, the most prevalent forms of keystroke malware include:

  • Phishing Emails - you can accidentally download a keylogger by clicking on a link in a phishing email or text message.
  • Viruses - cybercriminals often use Trojan viruses disguised as legitimate files or programs. Once you download and install them, the Trojan virus automatically starts keylogging your valuable information.
  • Zero-day Exploits - these security breaches occur when attackers discover some inherent security flaws in a system or program before the developers. They use this to deliver the malware before developers discover the programming fault.

The Biggest Threats of Keyloggers

To look at this topic from a different perspective for a second, keyloggers can be used for completely legitimate purposes, as we mentioned before. You can intentionally download them or purchase them from a trusted platform to perform various research activities.

Some of the most common examples of legal keylogger use include IT troubleshooting, user experience monitoring, or company-wide data monitoring and exchange. You can even use keylogging tools to monitor and supervise your children’s online activity by setting parental controls.

Unfortunately, there are many more negative examples of keylogger use. Moreover, the threats of keyloggers are numerous and often very worrying. If cybercriminals manage to set up a keylogger on your device, they can see and record everything you type. 

So, imagine just how much information they can collect by seeing your login credentials, emails, texts, and web browsing interests. After they steal your personal and sensitive information, they can exploit it for various criminal purposes.

For instance, cybercriminals can steal your identity, perform financial fraud in your name, use the collected data to ransom you, stalk you online, or perform many other nefarious misdeeds. This is why it’s crucial to learn how to prevent keylogging and learn how to detect whether you already have a keylogger installed on your device. This brings us to the next key point.

How to Detect Keylogging?

At this point, you’re probably worried by all of the potential dangers and disruptions keyloggers can cause you. This is certainly true, but luckily there are many practical things you can do to detect and remove keyloggers from your device. Here are some helpful steps you can take to detect and remove a keylogger:

  • Check Your Software
  • The first thing you should do is run through the list of all software you have on your computer. Be thorough and observant, as some keyloggers can blend with other software or be similar in name, making them harder to detect.

    Once you’ve found a suspicious program or file, remove or uninstall it. But, make sure to double-check, as even some programs that seem questionable might be necessary, so you should be certain that it’s not an essential tool before you delete it.

  • Check Your Browser
  • As we’ve mentioned briefly above, some keyloggers only focus on your browser, meaning that they only infect your device through browser extensions. Naturally, checking this is simpler than checking all of your software.

    If you discover any unfamiliar sounding extensions or any extensions that you haven’t activated yourself, make sure to deactivate and remove them, as they could potentially be malicious.

  • Perform a Factory Reset
  • Sometimes, even following the above steps won’t help you find any keylogging tools on your device. Plus, even if you find and remove some keyloggers, you can never be completely sure that you’ve got rid of all malicious software.

    This is why the best safety measure for removing keyloggers from your device is to perform a factory reset of the device. That way, you will wipe all data from your device, including any harmful files and software.

    How to Avoid Keylogging?

    While it’s useful to know how to detect keylogging software it’s arguably more convenient to learn proper keylogging prevention practices. In this regard, here are some of the best tips on how to prevent yourself from keylogging:

    Using a hardware security key and password manager like the Hideez Key ensures strong protection against keyloggers. As you will be eliminating the process of manually typing the information, the keyloggers won’t be able to record any of your login credentials or other valuable information.
