What is a Keylogger?

A keylogger is a type of malicious software (malware) designed to record the keystrokes made on a computer or device. When it’s installed, it operates silently in the background, capturing everything a user types. This can include sensitive information such as usernames, passwords, credit card details, and personal messages.

Keyloggers are a significant security threat because they can steal private data without the user knowing. The captured information is often sent to cybercriminals, who can then use it for identity theft, financial fraud, or unauthorised access to online accounts.

There are two main types of keyloggers:

  • Software-based keyloggers: These are installed on a victim’s device through malware. They run as background programs and are often hard to detect.
  • Hardware-based keyloggers: These are physical devices connected to a computer, usually between the keyboard and the computer. They record keystrokes directly from the keyboard before data reaches the computer.

 

Keyloggers can infect systems through:

  • Phishing emails: Emails that contain malicious attachments or links that, when you click them, install the keylogger.
  • Malicious websites or downloads: Infected websites or software can secretly install a keylogger on your device.
  • USB drives: Keyloggers can spread through infected USB devices.

 

To protect yourself from keyloggers:

  • Use reputable Endpoint Detection & Response (EDR) solution or up-to-date antivirus software to help you detect and remove malware.
  • Keep your software and operating system updated.
  • Never click on suspicious links or download any unknown files.
