Or MASM syntax such as "0Ch"

Very nice to see develoment progressing month for month. Back in 2014, I was hating every x64 debugging session. Now I can enjoy it. :D

Thanks alot for your contribution pal. Stay well. :)

Hello, the other day I started debugging this themida packed x64 game and it worked quite flawless. So I continued debugging it the next day and now I only seem to get "Breakpoint reached not in list". And it breaks only once. I'm also unable to single step and it only jumps from breakpoint to breakpoint. I updated to your latest release but nothing I did helped my case. Any idea what could be the root of this or you got any suggestions? Thanks :)

You have to upload your target somewhere & provide steps to reproduce.

Hi and thanks for replying back. Yea I know, but the problem is that it's a game and it requires 50gb to run.

Do you think it a good suggestion?

Hi,

I am looking for tutorials on how to unpack UPX using x64dbg.

thanks

cybercoder 09-28-2017 16:33

It would the same way to unpack as on olly or anything else. 'esp trick' I usually just scroll down and breakpoint on oep jmp though..

sendersu 10-19-2017 03:31

yes, eg: https://forum.tuts4you.com/topic/38620-unpack-upx-using-x64dbg/

@mr.exodia

niculaita 03-24-2018 22:39

Hi everyone, back to the RE world for the 1st time since 2014 and time to update my tools.
Since this is the new debugger to use, is there any plugin repo to use ?
Thanks a lot.

Hello, you can find it here;

wilson bibe 05-18-2018 18:55

I'm user of olly but as a reverser I'm curious about this debugger that certainly is very good, there are some plugin that do the same of breakpoint manager on olly? In the post above I didn't find nothing similar.

0x22 06-13-2018 17:36

This debugger is getting better and better. Absolutely amazing work by exodia.

sendersu 06-13-2018 18:13

maturity comes in years...
+huge amount of open-source community guys :
and girls!?: :)

Hypnz 06-14-2018 22:22

Mr.exodia and the contributors have made great job at x64dbg. Highfive guys!!!!

deroko 06-16-2018 14:43

One thing I always wanted to ask for :) When I have __debugbreak() enabled and attach as JIT, x64dbg breaks always on this int 3, and even if you set new origin after int 3 it somehow restores exception back to int 3 and usually solution is to replace int 3 with nop. Olly and windbg tend to break after int 3 thus exception doesn't reacquier.

This would be great imho :)

mr.exodia 06-17-2018 07:08

deroko: You can use the option 'Skip INT3 stepping' (https://i.imgur.com/JzPDRws.png), or manually use the `skip` command to achieve what you want.

Respect for your work.

deroko 06-18-2018 19:19

Ah sweet, had no idea this options is doing this. Tnx :)

winndy 06-18-2018 21:48

Cool!
Wish x64dbg could be cross-platform.

DavidXanatos 07-14-2018 14:54

I was trying to use this debugger the other day and run over a strange issue.

I was not able to make it ignore an exception thrown by the application (ExceptionCode: C0000005), as far as I can tell its part of a anti reverse engineering technique. in IDA the same exception gets thrown but there when I encounter the first one i can tell it to ignore all subsequent once.

I tried to uncheck all the "break on" checkboxes in the options as well as adding last exception and/or add 00000000-ffffffff to the excluded exceptions list but still it did not ignore the exception. I wonder if there is a bug (I was using the latest build as of yesterday) or if I missed some option.

If its the later than I would appreciate being pointed towards it and if its the former than a fix would be much appreciated to :)

Dicypher 07-27-2018 07:36

@sendersu Just followed the UPX tutorial, works like a charm.

I'll be working with some more advanced packers soon, after nailing down UPX. Mr. Exodia has done some awesome work with x64dbg... no doubt.

A quick skim over the merge requests and commit log show it was merged and combined a single editor. (Hex editor / string editor / data copy dialog into one. https://github.com/x64dbg/x64dbg/pull/1941)

WildGoblin 10-14-2019 21:17

Great tool, many thanks for it!

namreeb 12-27-2019 05:57

For anyone else interested:

There had been a bug with remapping code (including Blizzard games) that was fixed with this commit: https://github.com/x64dbg/x64dbg/commit/d50675ca025e3494de683d8510a681551e92c8ab

agoo 08-18-2020 15:15

screenshot is deleted. I wish we had an upload section for files to stay there for a long time. I am a member of digital networks forum for more than 19 years and most of the uploaded files are still inside the upload section.

atom0s 08-18-2020 17:37

You can find screenshots on their homepage if you are looking for examples of what it looks like:

agoo 08-18-2020 18:06

Wow great job. I liked DLL debugging feature. Good for Wibu codmeter people.

morgot 09-17-2020 06:48

Hello mr.exodia ,
are you planning to add such functionality? https://github.com/x64dbg/x64dbg/issues/2067 very need it.

And can you give me btc wallet for donate? You gave it to me on another forum (exelab) six months ago, but that forum died, but I don’t know how to write it in a personal note (sorry for the bad English).

The BTC wallet to donate is linked on the main page of x64dbg.

Jumping back to do something, have a question. I left x64dbg several months ago with a foreseen support for plugins. Does it support now? There is a list of good ones floating around?

Thanks
Shub.

Their GitHub has a list maintained here:
https://github.com/x64dbg/x64dbg/wiki/Plugins

There's a handful of others on Github itself that are pretty easy to find too.

Depends on what you need the plugin to do of course. There are a lot floating around though as atom0s mentioned.

Shub-Nigurrath 01-09-2021 18:12

I mean. With Olly there were some handy distros with pre selected plugins (those really working) or patches to do most of rce stuffs. Anything similar?
