member variable, virtual function table pointer, and then to the normal member variable. And then we'll see what it looks like in the virtual function table:A virtual function table is also an address that holds a virtual function for each item in 4 bytes. The address of the saved virtual function is discharged in the order declared by the function, the first one holds the virtual function of the first declaration, the second item holds the second one, and so on. Let's see what each item in thi

accounted for 10 bytes, to 4-byte alignment, so you need to complement two bytes, so two 0xcc, resulting in a 10 byte between the BF and array. The one next to the above array should be two 0xcc to complement the alignment. It was deliberately marked to the back. The purpose of this identification here is to illustrate the principle of checkstackvars this inspection. OK, clear the memory distribution, then checkstackvars at what time to perform the check, in C + + code can not be displayed to

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

local processor, which negatively affects the performance. Although the increasing execution speed of modern processors will eventually alleviate this problem, it is still obvious. One way for VM developers to speed up execution is to use a bytecode instruction set that is smaller than the local processor assembler. Local applications may contain up to 400 commands, while Java applications generally use up to 200 commands. Fewer commands mean that hackers can analyze code more quickly for rever

WinRAR is one of the most commonly used software. Since it is not a free software, after the trial period, every time you open winRAR, you will be prompted to register a dialog box, which is annoying. Therefore, my general practice is to download a lower version of winrar after it is cracked (the latest version of WinRAR is often slow to crack), so if you want to taste it, you have to wait for a while.I recently read "hacker disassembly and decryption

First, through the disassembly language, let's take a look at the relationship between the simplest recursive function and the stack. In Visual Studio 2008 and debug environments, you can view the language after disassembly in debug/Windows/disassembly. Now let's take a look at factorial n! Implementation The C language implementation code is as follows: #includ

select popular tools because these tools have been widely studied and have a general "Shelling" approach. 2. In addition to shell processing, it is best to embed anti-tracking code during software development to prevent "brute-force" tools from finding software registration vulnerabilities. There are many anti-tracking methods for the software. Common examples are the random change of the memory address of key code using the spending command. The following is an example. The initial source code

compiled by Delphi. Of course, it's important to use Dede disassembly to find the keyCode. After disassembly, find the "register" button in the "register" dialog box and click the response code at 0x004f0b60. The initialization code of the "register" dialog box is at 0x004f0d18. After Dede's work is done, open Ida pro disassembly. This tool is not only the kin
