What is a reflective DLL loader?
Reflective Dynamic-Link Library (DLL) loading, which can load a DLL into a process memory without using the Windows loader, is another method used by attackers. As such, an attacker can exploit a process, map the DLL into memory, and then reflectively load DLL without first saving on the disk.
What is reflection injection?
Reflective DLL injection is a technique that allows an attacker to inject a DLL’s into a victim process from memory rather than disk.
What does injecting a DLL do?
In computer programming, DLL injection is a technique used for running code within the address space of another process by forcing it to load a dynamic-link library. DLL injection is often used by external programs to influence the behavior of another program in a way its authors did not anticipate or intend.
What can DLL injection do?
What is DLL injection used for?
What is hook injection?
Hook injection describes a way to load malware that takes advantage of Windows hooks, which are used to intercept messages destined for applications. Malware authors can use hook injection to accomplish two things: To be sure that malicious code will run whenever a particular message is intercepted.
How is DLL injection used in Windows 10?
When you need to load a DLL in Windows, you need to call LoadLibrary, that takes the file path of a DLL and loads it in to memory. This method can also used to perform a DLL injection, that inserts code in the context of another process by causing the other process to load and execute code.
Is there way to detect reflective DLL injection in Windows?
Windows doesn’t have a LoadLibrary function that supports this, so to get the functionality you have to write your own, omitting some of the things Windows normally does, such as registering the DLL as a loaded module in the process , potentially bypassing DLL load monitoring. The process of reflective DLL injection is as follows:
How can DLL injection be detected in virtual machine?
If you want to avoid the process being able to detect your code you’ll have to either wrap everything in a virtual machine and then interact with the process from outside of the virtual machine.
How is DLL injected into open target process?
Open target process with read-write-execute permissions and allocate memory large enough for the DLL. Copy the DLL into the allocated memory space. Calculate the memory offset within the DLL to the export used for doing reflective loading.
