Notes on an ASM X64 Reverse Shell
Notes an ASM X64 Reverse Shell This article is a collection of Resources that i used to create a x64 reverse shell in pure ASM. Furthermore you can find the code that I wrote commented line by line. The Resources: The starting point Windows X64 calling convention GetProcAddress WSAstartup WSASocketA Sockaddr WSAConnect CreateProcessA STARTUPINFOA ExitProcess The Steps: Finding Kernel32.dll Address Parsing Kernel32.dll to find GetProcAddress API Using GetProcAddress to find LoadLibrary API Loading the ws2_32.dll Using GetProcAddress to locate and store WSAStartup address Using GetProcAddress to locate and store WSASocketA address Using GetProcAddress to locate and store WSAConnect address Using GetProcAddress to locate and store CreateProcessA address Using GetProcAddress to locate and store ExitProcess address Calling WSAstartup() Calling WSASocketa() Creating the sockaddr structure Calling WSAConnect() Pushing cmd.exe string to stack Setting STARTUPINFOA Structure Calling CreateP
