First. Acquisition of SHADOWSSDT Well, we've already got the original address of SSDT in R3 and the SDT, SST, and Kiservicetbale relationships mentioned: All SST is stored in the System Service Description table (SDT). There are two SDT in the system, one is servicedescriptortable and the other is Servicedescriptortableshadow. The Servicedescriptor only points to the Kiservicetable SST, while Servicedescriptortableshadow contains all two SS

Source code: hook ssdt source code According to Microsoft, the Service Descriptor Table is an array composed of four structures, each of which is composed of four double-word items. Therefore, we can represent the service Descriptor Table: Typedef struct servicedescriptortable { SDE servicedescriptor [4]; } SDT; Each service descriptor is in the form of four dual characters. Its structure is as follows: # Pragma pack (1) Typedef struct servicedescrip

In 32-bit Windows we have many methods for locating SSDT, most directly using the export symbols to find SSDT. And then there is through the nt! Disassembly search in the Keaddsystemservicetable function. However, neither of these methods is feasible in 64-bit Windows. In 64-bit Windows, you are not exporting SSDT, and nt! Keaddsystemservicetable is no longer out

In 32-bit windows, we have many methods to locate ssdt. The most direct one is to use the export symbol to find ssdt. Then there is through nt! Search by disassembly in the keaddsystemservicetable function. However, in 64-bit windows, neither of these methods works. Ssdt is not exported in 64-bit windows. In this case, the first problem occurs when you hook the

After two weeks of hard work, ssdt Hook was finally successful. Here, I would like to thank a great god in the forum. Thank you very much. What is his ID, after adding his friends, I remember the words Lenin under his name. It's a very interesting name. If you want to add a name, you can read my post. There are still a lot of top-level figures in the forum. We cannot use the level to measure a person's knowledge level, just as I saw a post about eager
