In this ticket we will try to fix the dummy shellcode problems and hopefully we will be able to execute it successfully.Introduction to Linux shellcode writing (Part 2) | Adventures in the programming jungleThe goal of this ticket is to write a shellcode that will open a socket on a specific port and executes a shell when someone connects to the specific port.How to write a (Linux x86) port-biding shellcode | Adventures in the programming jungleThe goal of this ticket is to write a shellcode that makes a connection from the hacked system to a different system where it can be cached by different network tools like net catHow to write a (Linux x86) reverse connection shellcode | Adventures in the programming jungleThe goal of this ticket is to write an egg hunter shellcode. An egg hunter is a piece of code that when is executed is looking for another piece of code (usually bigger) called the egg and it passes the execution to the egg. This technique is usually used when the space of executing shellcode is limited (the available space is less than the egg size) and it is possible to inject the egg in another memory location. Because the egg is injected in a non static memory location the egg must start with an egg tag in order to be recognized by the egg hunter.How to write a (Linux x86) egg hunter shellcode | Adventures in the programming jungleRegardsNO-MERCYSource: http://itblog.adrian.citu.name/category/it-security/shellcode/ 1 Quote
