Types of Fileless Malware
Below are two types of Fileless Malware.
- Windows Registry Manipulation: The attacker employs a malicious link or file that preys on a trusted Windows process to manipulate the Windows registry. For instance, the Windows process is used to write and run fileless code into the registry when a user clicks on the link. Like memory code injection malware, this type of fileless malware may evade detection by modifying the registry rather than using a malicious application.
- Memory Code Injection: The dangerous code that drives file-less malware is concealed inside the memory of otherwise benign apps using memory code injection. Programs employed in this type of attack are frequently necessary for critical operations. The virus runs code inside these approved processes. Phishing campaigns are another popular tool used by hackers to get access to their targets’ systems.
What is Fileless Malware?
Fileless Malware is malicious software connected to computers that only resides as a RAM-based artifact on the machine. It is difficult to find and eliminate because it doesn’t rely on files and leaves no trace. To get beyond defenses, adversaries of the modern day are developing more complex, targeted malware since they are aware of the tactics used by enterprises to try to stop their attacks. In this article, we will understand the workings of fileless malware, Types of Fileless Malware, and more.
