1 Outline n Define active and passive footprinting n Identify methods and procedures in information gathering Chapter #2: n Understand the use of social networking, search engines, and Google hacking in information gathering Information Gathering for the Ethical Hacker n Understand the use of whois, AR, and nslookup in information gathering n Describe the DNS record types 2 Phases of Hacking Footprinting n ECC describes four main focuses and benefits of footprinting for the ethical hacker: 1 Know the security posture (footprinting helps make this clear) 2 Reduce the focus area (network range, number of targets, and so on) 3 Identify vulnerabilities (self-explanatory) 4 Draw a network map 3 Essential Knowledge 4 1
2 Examples of Resources Passive Footprinting n Search engines n Gathering of competitive intelligence n Publicly facing web sites n Using search engines n DNS records n Perusing social media sites n Domain registration info n Participating in the ever-popular dumpster dive n Gaining network ranges n Raiding DNS for information 5 6 Passive Footprinting n Active Footprinting General business info n Social engineering n EDGAR Database (wwwsecgov/edgarshtml) n Robin Sage n Hoovers (wwwhooverscom) n LexisNexis (wwwlexisnexiscom) n Search engines n Business Wire (wwwbusinesswirecom) n Company plans and financials, the following list provides some great resources: n Google hacking n SEC Info (wwwsecinfocom) n Database with options * BS n Experian (wwwexperiancom) n Market Watch (wwwmarketwatchcom) n SiteDigger (wwwmcafeecom) - uses Google hack searches n Wall Street Monitor (wwwtwstcom) n MetaGoofil (wwwedge-securitycom) n Euromonitor (wwweuromonitorcom) n Fun lmgtfycom 7 8 2
