  2. Overview • CASE STUDY • An actual NYPD criminal case helped motivate this work. • A person, let's say Sam, was contacted on a Social Network, and decided • to go to meet this other person. The other person's intent was to rob Sam. • In attempt to escape, Sam ran into the street and killed by on-coming • traffic. This then became a homicide case. • SOLUTION • Developed security software tools, which can be used within Social • Networks, to help in tracking down criminals. • OBJECTIVES • Retrieve user’s non-personal-identifiable data, during users • Contact via the following Virtual environments: • Social Network Sites • Chat Sessions • E-mail • Website (Developed in Java) 2 VirtualForensics

  3. Topics • Technology Used Chart • Social Network Site • Data Retrieval using - PHP Scripting • Detecting Device Type • Detecting Mobile Device Model • IM Chat Session • E-mail • MAC Address Retrieval – Using Java Applet • Future Enhancements 3 VirtualForensics

  4. Technology ChartData Retrieval 4 VirtualForensics

  5. Social Network SiteData Retrieval • PHP Scripted Web Site: http://www.virtualforensics.net/track.php • Tracks the visitors to website • Can be integrated for use in tracking Social Network Site visitors. • Captures information of visited users • Stores retrieved user data to database • Appends retrieved user data to website for on-screen view • Social Network Tracking – SETUP PROCESS • Place the data retrieval PHP web link, into an image source tag syntax <img src="http://www.virtualforensics.net/track.php" border="0" style="visibility:hidden;" /> • Place above source tag into “Headline” section of your • MySpace or FaceBook: 5 VirtualForensics

  6. Social Network Site (cont.)Data Retrieval • The captured user data is stored to a database, and appended to list of visitors already in database. • All tracked visitor information is then retrieved from the database logs, and displayed to following link for on-screen viewing: • http://www.virtualforensics.net/ • Listing of Social Network Site user’s retrieved data: Visitor entry from database, for viewing on web 6 VirtualForensics

  7. Social Network SiteDetection of Device Type • PHP Scripted Web Site: http://www.virtualforensics.net/mobiledetect/detect.php • Detects the type of device used to login (PC, Mobile, etc) 7 VirtualForensics

  8. Social Network Site (cont.)Detection of Mobile Device Model • PHP Scripted Web Site: • http://www.virtualforensics.net/mobiledetect/detectmobile.php • Detects the Mobile Model (Blackberry, I-Phone, etc) 8 VirtualForensics

  9. Java AppletMAC Address Retrieval • MAC address • If assigned by the manufacturer, a MAC address (Media Access Control address ) encodes the manufacturer's registered identification number Display of retrieved user’s MAC address retrieved 9 VirtualForensics

  10. IM Chat SessionData Retrieval • NetStat • Is a command which retrieves other person’s IP address & MAC address of person you are chatting with. • MS-DOS prompt type the following command and press enter: NetStat –n 3 IP address of Local Machine and Foreign Machine 10 VirtualForensics

  11. IM Chat Session (cont.)Data Retrieval • IP address on the left hand side, 172.22.45.77 (see Figure 1) represents your IP address. The IP address on the right hand side, 172.22.47.248 (see Figure 1) represents the IP address of foreign machine. The 4 digit value following each IP address represents the port to which it is connected to. • You can connect to the foreign IP address by typing the following command. From • the MS-DOS prompt type the following command: C:\>nbtstat -A 172.22.47.248 the output 11 VirtualForensics

  12. IM Chat Session (cont.)Data Retrieval • On figure from previous slide (slide 10), the 172.22.47.248 represents the foreign machine’s IP address. • This entered command will output the values of: • Node • IP address • NetBIOS • Remote Machine Table • MAC address of Foreign Machine 12 VirtualForensics

  13. E-MailData Retrieval • Retrieve email sender’s IP address, by following below steps. Within a yahoo email account do as follows: • Go to inbox • Open your email • Click the drop down for Standard Header (see figure 3) • Click Full Header from the Standard Header’s drop down (figure 3 on next slide) • Dialog box with the IP information appears RESULTS: The sender’s IP address will appear in dialogue box. (Continued on next slide to view) 13 VirtualForensics

  14. E-Mail (cont.)Data Retrieval 14 VirtualForensics

  15. E-Mail (cont.)Data Retrieval IP address is 198.105.45.132 VirtualForensics

  16. Future Enhancements • Assigning the Java applet used to identify the Mac address of the client to the website • Retrieving the User Name of other user accessing the monitored Social Network page • Expand on fields to be retrieved during email communication. 16 VirtualForensics

  17. The End Thank you! 17 VirtualForensics
