RunPE technique

RunPE technique is a computer malware technique that is used to inject malicious code into a system. It is a type of process injection that creates an environment to execute malicious code within the context of a legitimate process. The malicious code is often disguised as a legitimate executable file or as an image file. RunPE is used by both attackers and defenders, and is commonly exploited by malware to gain persistence on a system.

The technique works by injecting malicious code into a legitimate application that is already running in the operating system. The malicious code can take control of the legitimate application to gain access to restricted system functions. The code can also securely store data or manipulate memory in the legitimate application’s address space or even infect itself in the application.

RunPE is widely used in a variety of malicious software, including banking Trojans, ransomware, and other forms of malware. It also has a number of legitimate applications, including anti-virus or system debugging programs. It is also used for system process monitoring.

RunPE is not an easy technique to detect as the injected malicious code is disguised as legitimate code. Furthermore, the malicious code can run in the context of the legitimate process, meaning that traditional signature-based detection mechanisms may not be as effective. However, there are detection tools that can detect the malicious code within the legitimate process, such as static or dynamic analysis, sandboxing, and memory forensics.

RunPE is a powerful technique for both attackers and defenders. Despite its potential for malicious activity, it can also be used for legitimate purposes, such as debugging and system monitoring. It is important for users to be aware of the malicious and legitimate uses of RunPE in order to better protect their systems.
