Threat actors are increasing and the strategies and methods used to compromise their targets are also growing.
From malicious software and hacking of computer networks, social media attacks, or theft of confidential information about a goal, malicious actors use all they can to break in the network of their target. There are various malware types present in the wild that allow a target computer system attacker to compromise.
One specific form of malware is malware that can be used by the opponents in the keylogging phase or by a keylogger, which the attackers use to monitor the keystrokes inserted into their computer device. This blog also discusses the numerous security effects of the deployment of a keylogger on a target device.
How Does An Attacker Use A Key Logger?
A threat actor can use different methods to access malware on the computer systems of a target organization. They could submit a fake email from a corporate IT department that could ask an employee to download and install some software that everyone wants. This would allow the attackers to move the keylogger to the victim’s computer.
Once the keylogger is mounted on the victim computer, all keys that are pressed into the keyboard connected to the victim’s machine will be registered or logged.
The keylogger can either send logged keys to and on threat actors, or it can store all keystrokes in a text file and send them to threat actors after a certain time, or it could also be possible for attackers to inject them in the source code of the keylogging malware.
Given that most information employees type while at work is normally vulnerable, a malware attack by keylogging may lead to substantial losses to the target organization. Let us say, for example, that if a computer system belonging to the financial department gets infected by malware that logs the key, the target organization might suffer monetary harm.
The threat may result in financial information such as bank account information, usernames and passwords of online bank accounts, and other financial information that attackers may use to steal money from the company, its customers, partners, suppliers, etc.
Most log files of keyloggers, usually stored on the target system first before being exfiltrated, but could be hidden and not visible to anyone, which makes it very difficult to detect them. Sometimes even if someone manages to find the log file for a keylogger, it may be possible to encrypt that log file or to use a file format that no victim’s software is capable of reading, and so the victim may not be able to know what the file includes.
This will render the victim unaware that she was the only target of a keylogger attack and had submitted to a cybercriminal all the personal details she might have put of her systems. The attackers are able to completely shut the lives of a victim and inflict immense harm to them by capturing a target keystroke.
Attackers may also use keyloggers to rob victims of their online identities, such as websites and social media, and causing victims to harm by reproducing them and forwarding falsified messages to their online contacts. This can damage the image of an individual among friends, family, and colleagues and lead to life chaos.
Preventive measures should be introduced to avoid keyloggers being compromised with computer systems and to deter cybercriminals from stealing sensitive information.
