[ASM shellcode Creator [Reverse Shell]]

 

 

 

asmTshell

 

is a exploit pen test application I developed for users using linux such as debian ubuntu or kali OS.

 

This tool allows you to build a reverse shell binary file and can be set to run on any OS be it windows linux or mac.

 

Once the target windows/linux/mac system runs the shell binary they connect to your server giving you full control of the systems command prompt or shell from your server.

 

 

 

It works by utilizing a linux asm compiler called "nasm"

 

It takes target asm payload and allows you to customize the payload to your desired IP and port # through a easy GUI. Once configuration is done from GUI it will edit your input to the needed ASM hex strings using a custom python script. After which it will compile your new ASM into your target binary file.

 

 

 

 

 

 

To get a server running you can use netcat nc or ncat

ncat -lvkp 1344
ncat to accept more than one client connection to server

nc -lvp 1344
netcat -lvp 1344

 

Once target system runs the shell binary they will connect to your server allowing you to control there OS from the shell.

 

 

 

**Limitations**

"keep in mind that your port or ip should not contain a 0, which could break it. If your IP contains a zero like 192.168.0.1 or your port contains a zero like 80, the build will not work"
