WHAT IS A KEYSTROKE READER AND HOW DOES IT WORK?
Updated on October 21, 2022, by Xcitium
What Is a Keystroke Reader?
A keystroke reader, also called a keylogger or keystroke logger, is a type of surveillance software or hardware that records every keystroke typed on a computer or mobile device. Cybercriminals use keyloggers to steal passwords, banking details, credit card information, and other sensitive data without the user’s knowledge.
A keystroke reader is considered to be a serious threat not only to consumers but also to companies. It causes identity and data theft and compromises the person’s privacy.
A keystroke reader is an application that records keys entered on the keyboard. This is not necessarily illegal software. In fact, it has many beneficial uses; companies can use it in employee and data monitoring. But in this article, we’ll discuss the malicious use of a keystroke reader and how hackers use it to steal sensitive information.
HOW DOES A KEYSTROKE READER WORK?
A keystroke reader works by secretly monitoring keyboard activity on a device. Once installed, the malware records every keystroke entered by the user and stores or transmits the information to attackers.
Most keyloggers operate through:
- malicious software downloads
- phishing emails
- infected attachments
- compromised websites
- Trojan malware infections
Advanced keyloggers may also capture screenshots, browser activity, clipboard data, or login credentials.
Intercept Keystrokes
A keystroke reader monitors keystrokes by positioning itself on the path that the keys you enter travel through. Then it intercepts keystrokes before the keys reach the application.
The information is saved on the internal memory of the software, then hackers retrieve it via a remote server. Hackers now have access to sensitive information.
Capture Screenshots
Sometimes keystrokes are not enough to gather information. So, hackers program a keystroke recorder to capture screenshots. The keystroke recorder turns on the camera without your knowledge and takes screenshots in the background.
Intercept Web Page Submission
Today, logging into our online accounts becomes part of our daily routine: We log into our social media and online bank accounts. This is an opportunity for hackers to steal usernames and passwords.
Through the use of a keystroke recorder, hackers can steal personal information stored on web pages. The keystroke reader secretly intercepts web page submissions to steal your personal information.
Records Chat Threads and Call History
Nobody wants to get their personal conversation compromised. Normally, we want to keep private conversations to ourselves unless we have a reason to share it. A keystroke reader can give the person who deploys it access to your personal conversations.
The information can be sent remotely to an email. The person responsible for the keystroke logger installation on your device can view your chat threads and call logs without your awareness.
That’s how malicious keystroke logging works. A keystroke reader infection doesn’t usually result in critical computer damage. So, it can be difficult to tell if it’s lurking in your computer.
However, if you suspect that there is indeed a malicious keystroke logging software on your device, you can check it out in Task Manager.
Open Task Manager, then go to the “Processes” tab. In that section, you will see all the active applications on the computer. Look for any suspicious applications in the list. Usually, malicious software has an unfamiliar publisher. If necessary, Google the application to verify if it’s malicious or not. Once you’ve verified that it is malware, end its process.
Another way to check if there’s a hidden keystroke reader on the computer is by doing a full malware scan. This is the process of deep scanning the computer to detect and remove malware. By doing a full malware scan, you can get rid of malware you would have never known was hiding on your computer.
A malware scan is accomplished through anti malware software. It is a program designed to combat threats to prevent malware infections. It consists of malware detection and removal tools to identify malware disguised as a legitimate executable file. Check out the best anti malware software for a personal computer.
If you are a business owner and want to scan your endpoint devices for a keystroke reader, we highly recommend Xcitium Advanced Endpoint Protection.
Types of Keystroke Readers
| Type | Description |
|---|---|
| Software Keylogger | Malware installed on a device to capture keystrokes |
| Hardware Keylogger | Physical device connected between keyboard and computer |
| Browser-Based Keylogger | Malicious scripts that capture form entries in browsers |
| Kernel-Level Keylogger | Operates deep within the operating system |
| Form Grabber | Captures web form submissions before encryption |
What Information Can a Keystroke Reader Capture?
A keystroke reader can steal:
- usernames and passwords
- banking credentials
- credit card numbers
- email conversations
- confidential business data
- cryptocurrency wallet credentials
- personal messages
Because keyloggers capture data before encryption occurs, they can bypass secure websites and encrypted connections.

Signs Your Device May Have a Keylogger
Common signs of a keylogger infection include:
- slow device performance
- unusual system lag
- unknown background processes
- suspicious browser behavior
- unauthorized network activity
- frequent crashes
- disabled antivirus protection
- unusual keyboard delays
Some advanced keyloggers operate silently and may not show obvious symptoms.
How to Detect and Remove a Keylogger
To detect and remove a keystroke reader:
- Run a full antivirus and anti-malware scan
- Check installed applications and browser extensions
- Monitor suspicious startup programs
- Review active background processes
- Update operating systems and software
- Use anti-keylogger or endpoint protection software
- Reset passwords after malware removal
Enterprise organizations should also monitor endpoints for suspicious behavior and unauthorized data transmission.
How to Prevent Keystroke Reader Attacks
Organizations and users can reduce the risk of keylogger attacks by:
- avoiding suspicious downloads and attachments
- enabling multi-factor authentication (MFA)
- using advanced endpoint security
- regularly updating software and operating systems
- scanning devices for malware
- avoiding public or unsecured devices
- training employees to recognize phishing attacks
Zero trust security and behavioral threat detection can help identify advanced keylogging activity before sensitive data is stolen.
Is a Keystroke Reader a Virus?
A keystroke reader is not technically a virus because it does not self-replicate. Most keyloggers are classified as spyware or Trojan malware because they secretly monitor user activity and steal sensitive information.
Examples of Keylogger Malware
Several malware families use keylogging functionality, including:
- SpyEye banking malware
- Remote Access Trojans (RATs)
- credential-stealing spyware
- phishing-delivered keyloggers
These threats are commonly used to steal financial information and corporate credentials.
Keystroke Reader: WHAT IS XCITIUM ADVANCED ENDPOINT PROTECTION?
Xcitium Advanced Endpoint Protection is a security solution for small to medium enterprises. Designed to protect business networks and endpoint devices, it is equipped with advanced malware detection tools to prevent malware infections.
Xcitium Advanced Endpoint Protection consists of the Host Intrusion Prevention System that constantly monitors the keyboard against a keystroke reader. HIPS analyzes any application that attempts to access the keyboard to ensure that no malicious application can hook the keyboard API to it.
The Host Intrusion Prevention System also protects the computer and its registry against sophisticated keystroke readers such as the Kernel-based keylogger. It is an application with the ability to load and execute directly from computer memory, thus being invisible in the file system.
Xcitium Advanced Endpoint Protection protects computer memory from malicious modifications to prevent advanced malware attacks.
Conclusion Keystroke Reader
A keystroke reader is an application designed to record keystrokes. This ability makes it a potent tool for stealing personal information. Since a keystroke reader works silently in the background, it is difficult to detect on the computer. One of the best solutions to detect and block it is to install a reputable anti malware software to take off the keystroke reader on the computer.
