Reflective DLL Injection is a technique that is used by attackers to inject malicious code into a running process. This technique involves the injection of a DLL (Dynamic Link Library) into a process without the use of traditional methods such as LoadLibrary. This technique is often used by attackers to evade detection by security software and to gain access to sensitive information on a system.
Traditional DLL injection methods require that the DLL be loaded into the target process using a legitimate function such as LoadLibrary. This can be easily detected by security software, which can then block the injection attempt. However, with Reflective DLL Injection, the attacker does not need to rely on any legitimate functions to inject the DLL. Instead, the attacker can use a specially crafted piece of code that can be loaded directly into the target process's memory.
This technique can be very effective for attackers, as it allows them to bypass security measures that are designed to detect traditional DLL injections. Additionally, Reflective DLL Injection can be used to execute malicious code directly in memory, which can help to evade detection by antivirus software that is scanning the file system.
To detect Reflective DLL Injection, organizations can use a number of different tools and techniques. One approach is to use behavior-based detection software that can detect the signs of an ongoing attack. This can include looking for suspicious network activity or monitoring for the creation of new processes.
Another approach is to use endpoint protection software that is designed to detect and block Reflective DLL Injection attempts. This software can be configured to monitor for the use of known Reflective DLL Injection techniques and can block any attempts to inject malicious code into running processes.
In order to prevent Reflective DLL Injection attacks, organizations should take a number of steps to secure their systems. This can include regularly patching and updating software, using strong passwords and two-factor authentication, and implementing security policies that limit access to sensitive information.
In conclusion, Reflective DLL Injection is a sophisticated technique that is often used by attackers to evade detection and gain access to sensitive information on a system. By understanding how this technique works and taking steps to detect and prevent it, organizations can better protect themselves from this type of attack.
