  1. Tool Names:1. VISION2. PASCO3. GALLETA

  2. Tool 1VISION

  3. Overview • Tool Description • Where You Can Find it • Applicability to Forensics • Tool Use/Screen Views • Observations • Lessons Learned UTSA IS 6353 Incident Response

  4. Technical Description: VISION • This Tool provides the following: • Shows all of the open TCP and UDP ports on a machine. • Displays the service that is active on each port. • Maps the ports to their respective applications. • Large amount of supplementary information that is useful for determining host status by displaying detailed system information, applications running, as well as processes and ports in use UTSA IS 6353 Incident Response

  5. Where to Find the Tools • www.foundstone.com • Featured in the free tools. • Information about Vision provided at www.foundstone.com/resources/proddesc/vision.htm UTSA IS 6353 Incident Response

  6. How The Tool Supports Forensics • Vision supports live analysis on a host. • Vision is a Host based forensic utility. • And it allows a forensic investigator to interrogate ports and identify potential “Trojan” services. • This tool supports “Incident Response” more than “Forensic Analysis”. UTSA IS 6353 Incident Response

  7. Tool Use • Vision is a windows GUI based application. • After launching, the application runs in the background and is located in the system tray. • Interval for “Auto-Refresh” can be specified in the options. • Vision can be used to log all the entries into a CSV file. UTSA IS 6353 Incident Response

  8. Basic Menu Screen View

  9. Observations • Easy to download • Easy to Install (Windows Installer and easy configuration) • Free tool • Easy to use navigation menus. Sub-menus can collapse and expand. A single view can represent a LOT of information. UTSA IS 6353 Incident Response

  10. Lessons Learned • Doesn’t work on Windows 98, Me • Requires ‘psapi.dll’ on Windows NT. • Single comprehensive tool which performs the functions of tools like ‘fport’ and ‘pstools’. • CSV log file can be a good resource for future reference. UTSA IS 6353 Incident Response

  11. Tool 2PASCO

  12. Technical Description of Pasco • This Tool provides the following: • Command line utility that parses information in the IE activity files (index.dat). • Index.dat files are in binary form and special tools, like Pasco, are required to view them. • Pasco is built to work on multiple platforms and will execute on Windows (through Cygwin), Mac OS X,Linux, and *BSD platforms. UTSA IS 6353 Incident Response

  13. Technical Description of Pasco • Relevant Fields in index.dat header UTSA IS 6353 Incident Response

  14. How Pasco Supports Forensics • This Tool supports off-line analysis • Allows a forensic investigator to reconstruct a subject’s web browsing habit. • Provide evidentiary material for abuse of internet corporate usage policies, pornographic content, other illegal activities. UTSA IS 6353 Incident Response

  15. Where to Find Pasco • On the web • Free utility • www.foundstone.com • Loaded on my directory • D:\Pasco UTSA IS 6353 Incident Response

  16. Tool Use • For Windows, must first install CYGWIN – a Linux like environment for Windows. • Cygwin can be found at http://sources.redhat.com/cygwin/ • Download and install Pasco from Foundstone site. • Search for index.dat files on system and copy into D:\pasco\bin. UTSA IS 6353 Incident Response

  17. Tool Use • For Windows XP, index.dat file can be found at these locations or do a search: UTSA IS 6353 Incident Response

  18. Tool Use • Pasco Usage: pasco [options] index.dat file to be parsed > output file.txt Options: -d Undelete Activity Records-t Field Delimiter (TAB by default) UTSA IS 6353 Incident Response

  19. Tool Use • Command line • Execute default mode of Pasco • $ ./pasco tif.dat > tif.txt (Parse the index.dat file and output result to index.txt file) • Execute undeletion mode of Pasco • $ ./pasco –d –t , tif.dat > tifdtoptions.txt UTSA IS 6353 Incident Response

  20. Typical command line usage of Pasco. UTSA IS 6353 Incident Response

  21. Text file output from Pasco. UTSA IS 6353 Incident Response

  22. Text file output from Pasco exported into spreadsheet for further analysis. UTSA IS 6353 Incident Response

  23. Observations • Easy to download • Small download – 460 Kb zipped file • Easy to Install • For Windows must first install CYGWIN • Simple command line use • Only two options available • Can be use to parse cookies and history index.dat files as well • White paper available for in-depth technical approach to Pasco development • http://www.foundstone.com/pdf/wp_index_dat.pdf UTSA IS 6353 Incident Response

  24. Lessons Learned • Works better when index.dat file is copied into wherever Pasco directory is located . • Run both default and undeletion mode to make sure no entries are missed. UTSA IS 6353 Incident Response

  25. Tool 3GALLETA

  26. Technical Description: Galleta • Galleta provides the following: • Internet Cookie analysis utility • Parses the contents of a Windows cookie file and outputs the result to a tab delimited file • Small download (<500Kb) • Requires CYGWIN to run • UNIX Bash Shell UTSA IS 6353 Incident Response

  27. Where to Find the Tools • CYGWIN installs to the root directory • www.cygwin.com • Large download (6.5MB) • Install from Internet • Galleta installs in Program Files directory or wherever you put it • www.foundstone.com/resources/proddesc/galleta.html UTSA IS 6353 Incident Response

  28. How The Tool Supports Forensics • Galleta supports off-line analysis • Tedious, cumbersome • Recovers the contents of a single Internet cookie file • Allows the investigator to categorize and/or sort cookies within Excel UTSA IS 6353 Incident Response

  29. Tool Use • Start CYGWIN • STARTAll ProgramsCYGWINCYGWIN Bash Shell • Change directories to the location where the Internet cookies are • Put the Galleta executable file in this same directory • From the UNIX prompt in CYGWIN type: • ./galleta cookiename.txt > newname.txt UTSA IS 6353 Incident Response

  32. UTSA IS 6353 Incident Response

  33. Observations • Easy to download • Easy to Install • Command line use was cryptic depending on level of experience • No Help support • Don’t forget to download CYGWIN • Very labor intensive UTSA IS 6353 Incident Response

  34. Lessons Learned • Watch out for location of Galleta executable • UNIX tool that works in Windows via CYGWIN • Best used in conjunction with string search utility (Pasco) to isolate questionable cookies UTSA IS 6353 Incident Response
