What Is A Key Logger
Keylogging, or keystroke logging, is a cyber attack that tracks a user’s keystroke on their computer or mobile device. Keyloggin may be installed on the device through malware, or victims can be targeted through phishing emails. Once a device is infected with keylogging, all keystrokes are sent back to the attacker through email or a remote server. The apparent harm is that cybercriminals can trace and use the victims’ login credentials nefariously.
Types of Key Loggers
Key loggers can be categorized into two types.
- Software – Software key loggers are usually programs installed on a computer without the victims’ knowledge or consent. Software keylogger programs are dangerous because they can be hidden in other programs.
- Hardware – Hardware key loggers are less standard than software key loggers attached to a computer’s keyboard cable or USB port.
How Key Loggers Work
Software keyloggers will monitor the keyboard input of a computer’s operating system. It records every key pressed, and the keylogger sends the information to the hacker over the internet to save to a local device.
Hardware keyloggers intercept signals between the keyboard and the computer, and the keylogger can then store the information in memory or send it to the cybercriminal over a wireless connection.
How To Protect Yourself From Key Loggers
Below are steps you can take to avoid becoming the victim of key logger attacks:
- Update software – Keep your web browser and operating system up to date, as this protects your data and network against known cyber vulnerabilities.
- Exert caution – Be weary of suspicious links, images, URLs, or websites because they can contain malware.
- Protect yourself – Use a security solution, including web filtering and malware protection, that prevents malicious activity from infecting your computer.
- Strong passwords – Strong passwords and multi-factor authentication can help reduce cybersecurity risks.
- Hardware keyboards – They are less vulnerable to keyloggers than software keyboards.
