What is the role of a Keylogger Trojan?

A keylogger is a type of spyware that monitors and records keystrokes made by users. They enable cybercriminals to read anything a victim types into their Keyboard, including private information such as passwords, account numbers, and credit card numbers.

Some keyloggers are capable of doing more than just stealing keystrokes. On PCs, Macs, iPhones, and Android devices, they can receive Data stealing copied to the clipboard and capture screenshots of the user's screen.

In hacking attempts, keyloggers are not always the only threat. They are frequently just one aspect of a multivariable cyberwarfare sequence, such as a botnet, ransom, or crypto mining attack.

Many victims are ignorant that they are being watched by keyloggers and continue to hand over sensitive information to cybercriminals.

You can learn cyber security by pursuing cyber security training online, and it can help you and your business prevent cyber attacks.

Please continue reading to learn how to detect keyloggers and prevent their covert installation.

What is the Process of a Keylogging Cyberattack?

The process of a keylogging cyberattack is determined by the type of keylogger used.

Keyloggers are classified into two types:

Software keyloggers and hardware keyloggers. The primary distinction between the two is the method of installing keylogger software.

1. Software Keyloggers

This is the most commonly used keylogger as it is the most effective way for cybercriminals' fast and large-scale distribution.

Keylogger software is frequently installed as part of phishing or social engineering attacks.

Nowadays, learning Cyber security is easy through a cyber security pg course available on the internet.

Throughout these attacks, a victim receives an email that appears to be innocent but is infected with malicious links or attachments. Interacting with any of these items triggers the installation of a hidden keylogger.

The Two Main Components of Keylogging Software are:

● A DLL (Dynamic Link Library) file

● An executable program

The executable file installs and launches the DLL file. When activated, the DLL file logs user keystrokes and sends the information to the cybercriminal's servers.

Once installed, a software keylogger could be used for any of the following categories of cyberattacks.

● Kernel Keylogger Attacks - Kernel mode keyloggers are the most popular keylogging software and the most difficult to detect. Kernel keyloggers use filter drivers to intercept privileged access credentials.

● Keylogger Attacks Using "Form Grabbing" - These keyloggers work by intercepting data entered into a website form before being transmitted to the network.

● API-Based Keylogger Attacks - A keylogger is placed at the Application Programming Interface (API) to apprehend keyboard strokes sent to a targeted software during these attacks.

● Malware-Infected Mobile Apps - Mobile apps infected with keylogging malware are made available for free download in app stores throughout this attack. In 2017, Google removed 145 Android apps from its Play Store that were infected with keylogger malware.

An online cyber security degree is quite essential to protect you from hacking attacks.

Hardware Keyloggers

Hardware keyloggers are physically connected to the device being monitored. These attacks necessitate cybercriminals physically manipulating targeted devices, while some can divert keystrokes without requiring a hardware connection.

The following are some examples of hardware keylogger cyberattacks.

USB Keylogger Attacks: In this attack, a USB device is connected to targeted computer systems to install keylogger hardware. Social engineering techniques such as the Trojan Horse are commonly used to persuade victims to connect infected USBs.

Attacks on Keyboard Hardware Keyloggers: A keylogger is physically built into a keyboard connection or within its keyboard software. This type of attack may appear to be extremely unlikely, but it does occur. In 2017, hundreds of HP laptops were shipped to customers with keylogging code-infected touchpad drivers.

Hidden Camera Keylogger Attack: A physical connection to the target device is not required for this type of attack. Hidden cameras are strategically placed near victims to record their keystrokes.

Detection and Prevention of Keyloggers

It would be best if you were cautious when opening attachments in general. Keyloggers could be embedded in files sent via email, text messages, chat rooms, networks, and even social media. Keep an eye out for suspicious emails requesting Data stealing.

It is critical to have an antivirus program that is up to date. When you turn off your antivirus, keyboard loggers are waiting for an opportunity to infiltrate your system.

Virtual Keyboard also aids in the prevention of private data interception by hackers. It is a piece of software that allows the user to enter characters without using physical keys.

Enabling two-factor authentication with such a one-time password would also help to protect you. Hackers cannot use the same passcodes again because the one-time password is only valid for a single session.

Tend to involve your phone number for access control, and keyloggers will not crack the real password.
