What is a Keylogger and Why Should You Care?

A keylogger (short for keystroke logger) is a type of malicious software or hardware device that records every keystroke you make on your keyboard. Cybercriminals use keyloggers to steal sensitive information such as:

• Passwords
• Credit card numbers
• Personal messages
• Confidential business data

Keyloggers can be installed through infected email attachments, malicious downloads, or even physical devices plugged into your computer.

Why Are Keyloggers Dangerous?

Unlike many other types of malware, keyloggers often operate silently in the background. You might not notice any performance issues, making them hard to detect. Once your keystrokes are captured, attackers can gain full access to your accounts and identity.

How to Prevent Keyloggers

Here are a few practical tips to protect yourself:

Use a Trusted Antivirus and Anti-Malware Tool
Regularly scan your system to detect and remove keyloggers before they cause harm.

Keep Your Software Updated
Operating systems and applications release security patches frequently. Apply updates promptly to close vulnerabilities.

Enable Two-Factor Authentication (2FA)
Even if your password is stolen, 2FA adds an extra layer of security.

Avoid Suspicious Links and Attachments
Do not click on unknown links or download files from unverified sources.

Use a Virtual Keyboard for Sensitive Transactions
Some keyloggers cannot capture clicks on virtual keyboards, making this a useful precaution for banking or payment sites.

Monitor Your Accounts Regularly
Check for unusual activity and act quickly if you notice anything suspicious.
