Pentest with Metasploit
18 likes24,429 views
This document summarizes a presentation about penetration testing with Metasploit. It introduces penetration testing and why organizations use it. It then discusses the basics of Metasploit, including interfaces like MSFconsole. Key concepts in Metasploit like exploits, payloads, and Meterpreter are explained. The presentation demonstrates Metasploit against different operating systems like Windows XP, Windows 7, and Ubuntu. It shows how to find and use appropriate exploits and payloads to gain remote access and post-exploitation activities.

Pentest with Metasploit
- 1. penetrationtesting withmetasploit Presented by Syarif ! Seminar IT Security Safe The System Sumedang, April 29 2012 STMIK Sumedang
- 2. Agenda • Why & What’s Penetration Testing ( Pentest ) • << back|track Overview • Metasploit Basics & Meterpreter • DEMO :)
- 3. Whoami • geek & Pentester • infosec trouble maker • InfoSec enthusiast • CyberCrime investigator • Lecture & Engineer
- 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. 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. Ethics • Think before act • Don’t be stupid • Don’t be malicious
- 7. Pentest Phases Vulnerability Analysis Information Gathering Exploitation Post Exploitation Reporting
- 8. << back|track overview • Let’s Watch theVideo :)
- 9. << back|track overview • . The Most Advanced Linux Security Distribution Open Source & Always be Developed for Security Professional Real World Pentesting Tools
- 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. Metasploit interfaces • MSFconsole • MSFcli • msfweb, msfgui ( discontinued ) • Metasploit Pro, Metasploit Express • Armitage
- 14. MSFconsole
- 15. MSFcli
- 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. How does exploitation works attacker exploit + payload vulnerable server 1 exploit run , then payload run 2 3 Upload / Download data
- 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. Meterpreter • as a payload after vulnerability is exploited *1) • Improve the post exploitation
- 20. Meterpreter Exploiting a vulnerability Select a meterpreter as a payload meterpreter shell
