A keylogger is a type of software or hardware that records keystrokes made on a keyboard.
Description
In the cybersecurity industry, a keylogger is a tool that captures and logs every keystroke made by a user on their keyboard. This can include everything from usernames and passwords to personal messages and sensitive information. Keyloggers can be installed as malware on a computer, often without the user's knowledge, or they can be physical devices attached to a keyboard. Cybercriminals use keyloggers to steal sensitive data for various malicious purposes, such as identity theft, financial fraud, or corporate espionage. For instance, the well-known malware 'SpyEye' included a keylogging feature that targeted online banking credentials. Keyloggers can operate silently in the background, making them particularly dangerous as users often remain unaware of their presence. Furthermore, businesses are at risk if employees inadvertently install keyloggers through phishing emails or malicious downloads. Protecting against keyloggers requires robust cybersecurity practices, including using antivirus software, regularly updating systems, and educating users about safe online behavior.
Examples
- SpyEye: A malware that includes keylogging capabilities targeting online banking users.
- Lazarus Group: A notorious hacking group known for deploying keyloggers in their cyberattacks to gather sensitive information.
Additional Information
- Keyloggers can be disguised as legitimate software, making them hard to detect.
- Using two-factor authentication can help mitigate the risks associated with keyloggers.
