A keylogger is a type of malicious software that records every keystroke made on your computer. Its main purpose is to collect sensitive information such as passwords, credit card numbers, and personal data—often without your knowledge. Keyloggers can be installed through infected emails, downloads from untrusted sources, or by exploiting vulnerabilities in operating systems.
How Does a Keylogger Work?
Keyloggers capture every input from your keyboard and send that data to a server controlled by the attacker. There are different types of keyloggers:
Software keyloggers: Installed as programs or add-ons within the operating system.
Hardware keyloggers: Physical devices that connect between the keyboard and the computer.
Consequences of a Keylogger Attack
Keyloggers can lead to serious consequences, including:
Identity theft: Stolen data can be used to access your personal accounts or create fake identities.
Financial losses: If attackers gain access to your financial details, they may perform unauthorized transactions or steal funds.
Compromised privacy: Keyloggers can record private conversations, emails, and other sensitive information.
How to Protect Yourself from Keyloggers
Use antivirus software: A regularly updated antivirus can detect and remove keyloggers. Choose reputable antivirus programs.
Be cautious with emails and attachments: Do not open suspicious emails or attachments from unknown sources. Always verify before downloading files.
Keep your software and operating system updated: Regular updates help protect against known vulnerabilities and threats.
Enable two-factor authentication (2FA): Adding an extra layer of security helps protect your online accounts even if your password is stolen.
Install browser security add-ons: Some extensions can help detect suspicious activities and block attacks.
Conclusion
Keyloggers pose a serious threat to your digital security and privacy. Understanding how they work and taking proper security measures can greatly reduce the risk of attack. Stay vigilant when using the internet and regularly scan your system for potential threats.
If you suspect your system is infected with a keylogger or need expert advice on protection, consult a cybersecurity professional.
