Mr. eXoDia,

First I want to say thank you very much for such a good idea and a wonderful work.

I just found about X64_dbg by chance 2 days ago, yesterday I saw you uploaded a new snapshot, I gave it a try it and it's working fine for me, I tired to compile the git head version and the process went smooth as expected.

I'm very impressed and I see x64_dbg has a good potential over others I tried in the past. I am trying now to learn more about it's internal and see where I can contribute , I saw the issue tracker hopefully I can reproduce some of the issues and it will be my first step to know more about how it works internally.

Thank you again for the Wiki, the help file, and the website and all the work you guys did.

I have couple questions, please tell me if there is another forum or post where you discuss, issues, features, design decisions..etc, I will appreciate it so much

Thank you and have a nice day

Thanks! You can come in contact using IRC (#x64dbg on Freenode) or by posting a topic in this forum (there is a special section for questions etc). You can also hit me up on skype/whatever or when I'm live on http://live.x64dbg.com

The latest snapshots (vs 13) do not work on XP SP3 32 bits.

Indeed. X64dbg is far away better than olly.

Hi, thank you for the x64dbg.


 


I am trying to open 64-bit dll, but it writes that PE is invalid (see the attachment)


What is wrong?


 


Thnx.

Thnx.

It is because your file is not a valid PE file (at least according to CFF Explorer)...

yes, sorry, it was modified.

I doubt there is, since I don't recognize the command :) However, you can very easily write commands yourself, by either writing a plugin or by sending me a pull request.

Soon I plan on deprecating this way of scripting anyway, but until then feel free to add commands :)

Hi.


Pardon my question, it may sound stupid.


How i can search in memory map a hex value on debugged file virtual space?

Posted

As far I know doesn't have search in memory feature:/ Or has and can't find it. At least I can't find it.

It was implemented in one of the latest snapshots. Look for 'Find Pattern...' in the memory map

@GIV: its an issue with ScyllaHide. See the readme file for a solution.

@GIV

NOTE: You need to put NtApiCollection.ini in the same directory as ScyllaHide.dll

or the following hooks will not work:

NtUserQueryWindow, NtUserBuildHwndList, NtUserFindWindowEx

Info about NtApiCollection.ini:

Some Nt* WINAPI functions are not exported by a DLL, so it is necessary to get

the function adresses from another source. The other source is the PDB file.

The adresses can be resolved with this tool: https://bitbucket.org/NtQuery/pdb-getprocaddress

It will download the PDB file from the Microsoft server to resolve the missing function adresses.

Binaries: https://bitbucket.org/NtQuery/scyllahide/downloads/NtApiTool.rar

Since he has gone capstone there are a few problems in both x64 and x32;They are launching many snapshots without any solution or change.
