All we need here is to HOOK the call to the change of money and wood. After all, other abnormal functions have already been written by our predecessors and there is no need to repeat the wheel. (If you are interested, you can analyze it yourself) You only need to determine the value of edx

follows:Figure 1 shell check for pandatvIt can be seen that this program is not shelled, so it does not involve shelling, and it is written by Borland Delphi 6.0-7.0. The Code Compiled by Delphi is different from the code written by VC ++. The two most obvious differences are as follows:1. When a function is called, parameters are not transferred completely using stacks, but mainly using registers. That is, the Delphi compiler transfers function parameters using register by default. This is tot

, the MOV instruction has a data format and two operands, so the general form is [Movx s D]. where x is the data format, S is the source operand and D is the purpose operand.Here's a simple example, such as we have an instruction for MOVL%edx%eax. The execution process is as shown.As you can see, the contents of the%edx register are copied to the%EAX register after the instruction is executed. It is necessa

model. Of course, this security model consists of multiple periods. Sometimes user-State jobs cannot be completed without the core-level functions, which is why native APIs are introduced. Native APIs are non-documented internal function sets and run in kernel mode. Native APIS exist to provide some ways to securely call kernel-mode services in user mode. A user application can call the native API exported by NTDLL. dll. A large number of functions exported by NTDLL. dll are used to en

, that is, taking the pixel (x, y) as the center, to (x-radius, Y) and (x + radius, Y) after the pixels are multiplied by weights, the new pixels are obtained and written to the corresponding points on the target image. The process ends. Since the above processing process only performs a "Ten" operation on each pixel of the image, the operation on each pixel point is greatly reduced, and the greater the fuzzy length, the more reduced. As mentioned above, the Q = 3 and r = 5 Fuzzy Operations only

A % eax B % ebx C % ecx D % edx S % esi D % edi Memory operand constraints (m) When the operands are in the memory, any operation performed on them will occur directly in the memory location, which is the opposite of the register constraint, the latter stores the value in the register to be modified, and then writes it back to the memory location. But register constraints are generally used
