Ethical Hacking Questions Medium
A keylogger is a type of software or hardware device that is used to record and monitor keystrokes made on a computer or mobile device. It is primarily designed to capture sensitive information such as passwords, credit card numbers, and other personal data entered by the user.
In hacking attacks, keyloggers are often used as a means to gain unauthorized access to a target system or to steal sensitive information. Once installed on a victim's device, a keylogger silently runs in the background, recording every keystroke made by the user. This includes login credentials, online banking details, and any other information entered through the keyboard.
The captured keystrokes are then either stored locally on the compromised device or sent remotely to the attacker's server. The attacker can later retrieve the recorded data and use it for malicious purposes, such as identity theft, financial fraud, or unauthorized access to the victim's accounts.
Keyloggers can be deployed through various methods, including phishing emails, malicious downloads, or exploiting vulnerabilities in software. They can also be installed physically on a target device if the attacker has physical access.
To protect against keyloggers, users should practice good cybersecurity habits such as regularly updating their software, using strong and unique passwords, being cautious of suspicious emails or downloads, and using reputable antivirus software that can detect and remove keyloggers.
