A backdoor is a tool used to gain remote access to a machine.
Typically, backdoor utilities such as NetCat have 2 main functions: to pipe remote input into cmd or bash and output the response. This is useful, but it is also limited. BetterBackdoor overcomes these limitations by including the ability to inject keystrokes, get screenshots, transfer files, and many other tasks.
Features
BetterBackdoor can create and control a backdoor.
This created backdoor can:
To create the backdoor, BetterBackdoor:
If a JRE is packaged with the backdoor, execute run.bat, otherwise execute run.jar.
This will start the backdoor on the victim's PC.
Once running, to control the backdoor you must return to BetterBackdoor and run option 1 at start while connected to the same WiFi network as the victim's computer.

BetterBackdoor overcomes these limitations by including the ability to inject keystrokes, get screenshots, transfer files, and many other tasks.
Features
BetterBackdoor can create and control a backdoor.
This created backdoor can:
- Run Command Prompt commands
- Run PowerShell scripts
- Run DuckyScripts to inject keystrokes

- Send and receive files to and from victim's computer
- Start a KeyLogger
- Get a screenshot of victim's computer
- Get text copied to victim's clipboard
- Get contents from a victim's file (cat)
To create the backdoor, BetterBackdoor:
- Creates 'run.jar', the backdoor jar file, and copied it to directory 'backdoor'.
- Appends a text file containing the server's IPv4 address to 'run.jar'.
- If desired, copies a Java Runtime Environment to 'backdoor' and creates batch file 'run.bat' for running the backdoor in the packaged Java Runtime Environment.
If a JRE is packaged with the backdoor, execute run.bat, otherwise execute run.jar.
This will start the backdoor on the victim's PC.
Once running, to control the backdoor you must return to BetterBackdoor and run option 1 at start while connected to the same WiFi network as the victim's computer.
Demo
Requirements
- A Java JDK distribution >=8 must be installed and added to PATH.
- You must use the same computer to create and control the backdoor.
- The computer used to create the backdoor must be on the same WiFi network as the victim's computer.
- The IPv4 address of this computer must remain static in the time between creating the backdoor and controlling it.
- The computer used to control the backdoor must have their firewall deactivated, and if the computer has a Unix OS, must run BetterBackdoor as 'sudo'.
