![]() Start your XP guest in the debug mode (2nd option). It consists of two steps: (1) manually add a COM port in Control Panel and (2) manually configure COM1 as the port number. You can follow jorgensen's tutorial on " How to Add a Serial Port in Windows XP and 7 Guest" (follow the XP part). In some versions of XP, COM ports have to be manually configured.

This is to set up a second booting option for the debug mode. We need to further configure the XP guest to make it work. The installation of WinDbg on the host machine can follow the instructions on MSDN. In the following we assume that the pipe path on the host machine is \\.\pipe\com_11 and the guest OS is using COM1. Pay special attention to Seciton 3.1 (how to set up the serial port of the XP Guest). If you have not installed the guest VM, please follow the instructions of Tutorial 1. Before we proceed, we need to configure it properly on the host machine and the guest XP. In addition the the immunity debugger, we are going to use WinDbg in this tutorial. In the following, we use an experimental approach to explore the possible ways to make a program behave differently when running in a virtual machine and debugged environment. The behavior of int 2d instructions may be affected by many factors, e.g., the SEH handler installed by the program itself, whether the program is running under a ring 3 debugger, whether the OS is running in the debugged mode, the program logic of the OS exception handler (KiDispatch), the value of registers when int 2d is requested (determining the service that is requested). Find out as many ways as possible to make a program run differently in a debugged environment from a regular execution (using int 2d)?.Basic control flow constructs in x86 assembly.Debugging and modification of binary executable programs.Explore the behavior difference of debuggers on int 2dh.Otherwise, part of the erased data might be recovered from your iCloud backup or iTunes backup. After erasing data, why the previous erased data is still existing?Īfter you have erased data, please don’t log in your Apple ID account and password. Erase Deleted Files option in Umate Pro will fully remove previously deleted files as well as overwrite them. ![]() ![]() What does “Erase Deleted Files” mean?ĭeleted files can be recovered if these aren’t overwritten. After such intricate removal process, even the FBI cannot recover your data from the device. ![]() Then it again deletes the files and refills data again until recovery becomes impossible. Once the process of erasure is complete, Umate Pro will store random data on your device storage to overwrite deleted files. Umate Pro removes the original files in your device including the ones marked as deleted. How iMyFone Umate Pro permanently erases data? The file only gets marked as deleted but isn’t actually removed. Why should I permanently erase data?īecause "simple deleting" just erases the pathway to the information and it remains recoverable if right tools are used. ![]()
