Keylogger Tool

1. Understanding Keyloggers

Initially, Keyloggers were computer programs designed to monitor and record keystrokes into a log file. Nowadays, this software has evolved to not only record keyboard inputs but also capture screen shots, record display videos, and track mouse movements. Therefore, upon installing such software, the installer quickly gains access to social media accounts, bank accounts, message contents, emails, and more.

2. Impacts of Keylogger Software

Today, Keylogger software is not only used within IT organizations to aid in troubleshooting network technical issues, computer networks, or for household use to monitor computer usage by family members. They are also installed by malicious black hat hackers to steal login passwords for social media, online banking accounts, and other confidential information. As a result, your security information becomes easily accessible to hackers.

3. Preventing Keyloggers

Change Keystroke Order

If you want to log into your social media or online banking accounts, it's advisable to type the wrong password and then delete the incorrect characters to prevent the keylogger from recognizing the correct password.

Copy Character String

Alternatively, you can store passwords in Notepad++, Word, so that when accessing accounts, you simply need to copy the corresponding password to log in.

Use Antivirus Software

By installing robust antivirus software, your computer will be able to detect viruses and even keylogger programs. Additionally, consider setting up a firewall within the operating system and browser to prevent keyloggers from being installed and infiltrating your computer.

Utilize Virtual Keyboards

A simple, common yet effective way to prevent Keyloggers is by using a virtual keyboard. When you use a virtual keyboard, you won't be using the physical keys on your computer, so the Keylogger won't record any actions when you're using the computer.

Therefore, for safety, you should use a virtual keyboard and employ typing tricks to deceive this Keylogger software.
