  1. Analysis of the FimbelKeylogger and Pace University Converter Christopher Funk, Sheryl Hanchar, and Ned Bakelman

  2. Pace University Keyloggers • Record Keystokes • Not intrinsically good or evil • Potential Uses • Data Grabbers (Evil) • Active Identification (Good) • Visibility of Keyloggers • Rootkit vs. Normal Process

  3. Pace University Tools for finding Anatomy of any program • Analyze it as if it was malicious software • Ultimate Packer for eXecutables (UPX) • Fakenet – Network Diagnostics • Process Explorer – Process Information • OLLYdbg – Showing Flow of Program • IDA Pro – Interactive Disassembler • CFF Explorer – Decompile .Netdirectory

  4. Pace University Keylogger Software Pack • Originally three programs • FimbleKeylogger • Pace Keylogger Launcher • Focus of in-depth analysis • Pace Converter • Newer Version is two programs • Combined the two Pace tools

  5. Pace University Pace Keylogger Anatomy • Opens connect to Pace Server that remains open • User Agent is a .Net program

  6. Pace University Pace Keylogger Anatomy • UPX strings showing where the program is sending the data • Password is blacked out

  7. Pace University Pace Keylogger Anatomy • Process Explorer showing the call to start the FimbleKeylogger

  8. Pace University Pace Keylogger Anatomy • Ollydgb showing uniquely .Net Calls

  9. Pace University Pace Keylogger Anatomy • IDA Pro showing .Netboolean variable • Says if Fimble is running • Very Visible Program

  10. Pace University Pace Keylogger Anatomy • CFF Explorer – only works with .Net programs • Entry Point where malicious software can take control • Or just inject code into other benign program

  11. Pace University Pace University Combination Project Breakdown • Goal – Combining Software Tools • Keylogger Launcher • Converter • Issues • Different Programming Languages • External Program Control from Java Environment • Parallel work being done by customer on code

  12. Pace University Pace University Two Different Tools

  13. Pace University Pace University Goal Breakdown • Expanding converter to encompass launcher functions • Start and Stop the keylogger • Working with previous code • Naming Convention • Identify keylogging target application • Field for name information • Numbering Outputs • Adding in customer revisions

  14. Pace University Pace University Step 1: Working with Previous Code • Compiling issues when exporting to Jar • Netbeans Meta data • Very messy code • Did not follow best practices • Obsoleted code that still was in use • Main() issues • Moving it from Login() class to converter() class

  15. Pace University Pace University Step 2: Start and Stop Keylogger • External Program Executioner • Java Process Builder / Process classes • Issues • Unable to find the program • Documentation does not specify necessary parameters • Error Messages Unclear • Working only on one machine • Re-arranging GUI and how to identify the keylogger

  16. Pace University Pace University `ProcessBuilder builder = newProcessBuilder(keyloggerDirectoryField.getText() + "startkeylogger.exe"); builder.directory(new File (keyloggerDirectoryField.getText())); Process javap = builder.start();`

  17. Pace University Pace University Step 3: Naming Convention • LastName_Firstname_Application_Number.xml • Identify Target Program • Drop down menu • Hard coded string, not filtering the output • Name information • Fields where there but by default were invisible even though necessary • Numbering • Had to find the last number with the name output name and then iterate

  18. Pace University Pace University Step 4: Combining Customer Code • Costumer has added to the code after the original version that was combined • Need for communication after last step to make sure that his new changes work with new code • Did not change the converting code classes • Allows for change as the code as long as the function calls stay the same

  19. Pace University Pace University Communication with Customer / Testing • Constant email communication • Only one meeting at the last class • Very easy to work with • Indispensable to combining project • Test it on other machines to ensure it was working • Try out functions in different ways • Guide my steps to ensure all necessary functions were worked on first • Work with the previous code and understand what the function did

  20. Pace University Pace University Final KeyLogger Launcher and Converter

  21. Pace University Questions, Comments, Concerns, or well wishes
