Tcp To Serial Python' title='Tcp To Serial Python' />Filippo Zin. Zloun Bersani. The site is loading, please wait. GET ROOT OR DIE TRYIN. Here I will collect my experiences trying to understand something more about. I mean this is a site for noobs that have the will to learn something sound familiar maybe. There are a lot of tutorials about the stuff that Im going to write here, so why another one Actually I do not have a proper answer, here there is nothing special actually. MASTER you can immediately leave. Its only a diary to not waste my experience like tears in the rain. In the end I do not care too much. To read these articles I assume that you are able to program in some language, that you have an idea of what is NASM assembly and how the stack and related memory register work. Intel. 32 architecture. If you dont know this stuff I suggest to learn it before to start, it should not take too much, anyway the articles have a practical approach to. I will leave to reader the duty to learn the theory. Tcp To Serial Python' title='Tcp To Serial Python' />I do not know too much but based on my poor experience follows some advises. Never give up to learn. No matter how many things you know, more important that you know how these things work. Go beyond the facades and the walls. Keep it simple. Do not take that stuff too seriously. Always stay on the bright side. Finally the usual recommendation this stuff is intended for educational purposes only, Im not responsible in any way for any misuse of this material. I do not use any kind of technology to track or to save your personal information including cookies. I do not have any statistic about visitors activated and I do. IP or your geo localization info. The technology used in this site are HTML 5, Java. Script CSS only. Consider that this is site is hosted by Aruba Shared Hosting so that the previous assertions could be in some way denied. Here you can get more information about the terms of use and. Netcraft query for this site. Anyway the site is fully navigable using a TOR Bundle. For any suggestion. I will happy to read itSalu.

R2 6. 4A brief introduction, general problem with Win sc Since the release of Windows Vista in 2. Address space layout randomization ASLR is enabled for executables and dynamic link libraries specifically linked to be ASLR enabled. API functions at runtime, that leads to another problem since the function addresses are relative. How we try to solve these problems. Find the base address. We are obviously interested in kernel. Find the RVA of the functions we need. Relocate the address of the functions to get the real one. What we need to follow this tutorial NASM compiler for windows. Go. Link linker. A Windows machine Vista. I strongly suggested, in case you dont have it yet, to install. Immunity Debugger to understand what happens during the execution of the code. You can download the requested tool with the source code for this tutoria here. Before to get our hands dirty some theory to better understand what we are doing. Thread Environment BlockTEB is a structure used by Windows to describe a thread. Each thread can access to his own TEB by using the register FS on x. The TEB has the following structure we just mention the important information. Nt. Tib NTTIB. Environment. Pointer Ptr. Void. Client. Id CLIENTID. Active. Rpc. Handle Ptr. Void. 0x. 02c Thread. Local. Storage. Pointer Ptr. Void. 0x. 03. 0 Process. Environment. Block Ptr. PEB. 0xff. 0 Effective. Container. Id GUID. So to access the PEB pointer Ptr. PEB we can reference fs 0x. FS is a segment register that was added with the release of protected x. Typically, in win. FS points to the base of the TEB aka Thread Information Block TIB of the current active thread in the PE portable executable file. TIBTEB by fs 0. FS 0 stores the pointer to the first SEH structured exception handling and this is usually called when an exception occurs in code. FS points to the current active thread, this means a single application with multiple threads will have multiple pointers to different Thread Blocks. Process Environment Block abbreviated PEB is a data structure in the Windows NT operating system family. Follows an image of the retrieving schema The PEB contains data structures that apply across a whole process, including global context, startup parameters, data structures for the program image loader. Among the structures fields theres a pointer to a PEBLDRDATA structure providing information about loaded modules through we can obtain the base address of kernel. PEBLDRDATA. ULONG Length 0x.

Any binary executable file has to include a header to describe its structure including the list of functions that can be exported from the executable. When the file is executed the OS reads the PE header information first, and then loads the binary data from the file to populate the contents of the data segments. When an executable file is dynamically linked means of course that the system calls have not statically references in the executable itself. OS has to rely on the files import table to determine where to find the addresses of the system functions needed. Most binary executable files on Windows follows the following structure DOS Header 6. PE Header Sections code and dataThe last 4 bytes of the DOS header points to the location of PE header in the executable file, so 6. PE header consists of three parts a 4 byte magic code a 2. IMAGEFILEHEADER a 2. IMAGEOPTIONALHEADER3. We are interested in the first entry the pointer to the beginning of the export table 1. Following the structure with the relative offset. IMAGEEXPORTDIRECTORY. DWORD Characteristics offset 0x. DWORD Time. Date. Stamp offset 0x. WORD Major. Version offset 0x. WORD Minor. Version offset 0xa. DWORD Name offset 0xc. DWORD Base offset 0x. DWORD Number. Of. Functions offset 0x. DWORD Number. Of. Names offset 0x. DWORD Address. Of. Functions offset 0x. DWORD Address. Of. Names offset 0x. DWORD Address. Of. Name. Ordinals offset 0x. The PE loader and the bad guys like us knows the names of the functions, we have to obtain the addresses of those functions then, so having a function name. The formula is. assume Namesx. Function. Name then. FunctionsOrdinalxWe have 3 arrays to take into consideration Address. Of. Names Address. Of. Name. Ordinals Address. Of. Functions. Array index starts from 0 and indexes x are the essential linkage between Address. Of. Names and Address. Of. Name. Ordinals, so the 2 arrays have the same number of elements.
