(i) the foregoingYou can modify the IP, or both CS and IP instructions are collectively referred to as transfer instructions .The transfer behavior has the following categories: When you modify IP only, it is called intra-segment transfer, for example: JMP ax. Simultaneous modification of CS and IPs is called inter-segment transfer, for example: jmp 1000:0. because the transfer instruction

to load the program. There will be many loops in the shell program. When dealing with loops, you can only let the program run forward, basically not let it jump back, you need to think out of the loop. Do not use Peid to query entries. You can track entries in one step to improve the capability of manual entry searching.Load the program with OD.Confirm an entry warning, and the Od prompts the program to shell.

are collectively referred to as transfer commands (We will conduct further research later ). Now we will introduce the simplest command to modify CS and IP addresses:JMP refers to the order. If you want to modify the Cs and IP content at the same time, the command can be completed in the form of "JMP segment address: Offset address", as shown in figure JMP 2ae3: 3, after execution: cs = 2ae3h, IP = 0003 H,

overflow, and then we'll see how we can exploit the vulnerability. Vulnerability utilization To exploit the vulnerability, you must find a string offset that overrides the return address. We can send aaaabbbbccccddd by sending ... Such a combination string looks at exactly where the return address is overwritten. After some analysis, it is learned that at 4056 of the offset is exactly the cover of the function return address. So we're going to design an overflow string like this: GET/AAAA....|

bidirectional table Chi-square test (chi-square test)The chi-square test is usually used to obtain statistical significance of the relationship between variables, and it examines whether the characteristics shown in the sample are sufficient to reflect the overall characteristics. Chi-square test the difference between the predicted frequency and the actual frequency based on one or more categories of variables in a bidirectional table, which returns the probability of a chi-square distribu

The call [target function] jumps to the address of the JMP [function address] command before JMP is directed to the first address of the target function. Ofsfuncaddr is used to save the offset of the

It is also a bunch of antidebugger... and finally jumps to the real OEP of the program to deal with such shells.The method is to first find the OEP and then fix the IAT When the shell jumps to OEP, it is generally a cross-segment jump. There are many jump methods, such as jmp xxxxxxxx,

According to the previous practice, the EIP and ESP buffer must have a format created by metasploit. Copy these values, we will use them to calculate the differences between EIP and ESP registers in bytes. In this example, the values of EIP and ESP are: EIP: 69413269ESP:

I have seen some people asking me how to remove the bjfnt 1.2 shell over the past few days. So I wrote this article because the latest version is version 1.3, so I will only talk about the 1.3 shell here, I think 1.2 is simpler than 1.3. of course there are countless experts here, but they don't have time to write something out, so I just have to do it. There are countless instructions. My total experience is to keep F8 until I can see that a loop cannot go through, and then stop and analyze it.

With these tools and materials, you can clearly understand the details of the code to be executed within the system. From the preceding section, we can see that the First Command executed by the GetTickCount API is mov. If you can change the Opcode of mov to
