ELF (Executable and Linkable Format) is the standard binary format used by Linux and many Unix-like systems for executables, shared libraries, and object files.
An ELF file is divided into structured components:
ELF Header: The entry point of the file. It defines the file type (executable, shared, object), architecture (x86, x64), and offsets to other important tables.
Program Headers (Segments): Describe how the binary should be loaded into memory at runtime. The loader uses these to map code, data, and other regions.
Section Headers (Sections): Used mainly for linking and analysis. Examples include .text (code), .data (initialized data), and .bss (uninitialized data).
Entry Point: The address where execution begins.
This separation allows ELF to support efficient loading, dynamic linking, and modular binary design.
Follow below steps to configure your Lab Machine:
Download the LabMachine.ova file and import it in your Virtual Box
Download the ssh_Ubuntu.sh file in your system ( Linux ).
Give the execute permission:
Linux$: chmod +x ssh_Ubuntu.sh
Open the ssh_Ubuntu.sh in any text editor
Replace the <IP address> with your LabMachine ip address and save the file.
Now you can execute this ssh_Ubuntu.sh to login into your lab machine:
Linux$: ./ssh_Ubuntu.sh
Password is toor
In this section we will learn how to track down function input arguments inside the stack area.
Download the lab virtual machine image file and Import the (.ova) lab machine image into virtual box, ( username: professor, Pass: toor ) to follow the all the practicals.
Note: please disable the aslr before doing this practical:
sudo echo 0 /proc/sys/kernel/randomize_va_space
In this course of Exploit Development Tutorial for Beginners to Advanced Hacks you will learn the skills required to develop and create exploits from linux and windows programs. First this course of Exploit Development Tutorial for Beginners to Advanced Hacks will focus on the basics then it will dive into indepth concepts of vulnerabilites like buffer overflow, stack buffer overflow, format string buffer overflow, Data Execution Prevention, ASLR, ROP etc. You will learn how to use debuggers like IDA ,gdb, dbgx64, immunity debugger etc in order to develop your own exploit. You will learn how to create you exploits by performing fuzzing, shellcoding, building the payload then triggering the payload after the exploit runs. In this course of Exploit Development Tutorial for Beginners is for begginers as well as advanced hackers who wants to learn in depth skills of exploit development process. Exploit Development process is time consuming and needs basics to be cleared before like you should know how a binary works inside linux and windows. This course of Exploit Development will teach you how to master in developing the zero day exploits in modern binary applications. You will learn most advanced topics of ethical hacking in this course.
