Keylogger is a type of surveillance software that records every keystroke made on a computer to gain access to passwords and other confidential information. Keyloggers can be used for legitimate purposes, such as monitoring employee activity, but are often used maliciously to steal sensitive information.
Types of Keyloggers
- Software Keyloggers: Programs installed on a computer that log keystrokes and can capture screenshots, clipboard content, and more.
- Hardware Keyloggers: Physical devices connected to a computer's keyboard or USB port to capture keystrokes directly.
- Remote Keyloggers: Keyloggers that transmit captured data to a remote server controlled by the attacker.
Uses of Keyloggers
- Employee Monitoring: Employers may use keyloggers to monitor employee activity and ensure productivity and compliance.
- Parental Control: Parents may use keyloggers to monitor their children's online activity and protect them from harmful content.
- Malicious Purposes: Cybercriminals use keyloggers to steal passwords, credit card numbers, and other sensitive information for identity theft and fraud.
Risks and Consequences
- Privacy Invasion: Keyloggers can infringe on personal privacy by monitoring and recording all user activity.
- Data Theft: Malicious keyloggers can lead to the theft of sensitive information, financial loss, and identity theft.
- Legal Issues: Unauthorized use of keyloggers can result in legal consequences, including criminal charges and lawsuits.
Protection Against Keyloggers
- Use Antivirus Software: Regularly scan your computer with updated antivirus software to detect and remove keyloggers.
- Enable Two-Factor Authentication (2FA): Use 2FA to add an extra layer of security to your accounts, making it harder for keyloggers to steal your credentials.
- Be Cautious with Downloads: Avoid downloading software from untrusted sources and be cautious of email attachments and links.
- Regularly Update Software: Keep your operating system and applications updated to protect against known vulnerabilities that keyloggers may exploit.
