Virtual Section Dumper v1.0 x86

Author: NCR

# Views: 3554

Hi All!,

I just want to share my latest tool: VSD x86.

You can get it here: http://code.google.com/p/virtualsectiondumper/

"""
VSD (Virtual Section Dumper) is intented to be a tool to visualize and dump the memory regions of a running 32 bits process in many ways. For example, you can dump the entire process and fix it PE Header, dump a given range of memory or even list and dump every virtual section present in the process.
"""

BR,
NCR

If we manipulate the values of ImageBase in Process Environment Block (PEB) and PEB_LDR_DATA, the process won't be listed.

What do you propose to deal with that situation?. Any idea?.

You can call the "ZwQueryInformationProcess" function with the ProcessInformationClass set to ProcessImageFileName to retrieve the full name of the main executable and then read the ImageBase value from Disk (CreateFileA/ReadFile).

N.B. Also, if you use the "CreateFileA" function to read from the file, we can still defeat it by calling the "CreateFileA" function with the "dwShareMode" set to Zero.

I just added the x64 version to the web and released a bugfix version v1.1 x86.

Opening this tool while the file below is running will cause it to go into an infinite loop. Actually, many other tools are affected. http://ollytlscatch.googlecode.com/files/loop.exe
