x64dbg VS scapy

I have never heard anyone say anything good about the Visual Studio debugger before. Now, I'm not a Windows person but I'm not gonna argue for gdb or lldb here. RemedyBG and x64dbg are the two debuggers I've heard good things about though I've never used them because, again, not a Windows person.

I'd help you out but because of circumstances I have no laptop with me. You need x86/x64 debugger to do this. This one for example Find a registration procedure and look for possible brenching to other parts of code in assembly. It's probably somewhere in the beginning. Exclude code validation and export new program version.

One interesting thing you can do is download an app like https://x64dbg.com/ or cheat engine, which will let you see the memory. You can look at the process for something you’ve made and explore it. Log a memory address from your app then go find it in the tool and interpret the bytes as an integer. Find a string and see how that works. Find a pointer, read the address it’s pointing then go look at that address. You start to see how different containers store data. I find it fascinating.

If you want to also do dynamic analysis (debugging) you can use https://x64dbg.com.

close origin and download this debugger https://github.com/x64dbg/x64dbg/releases

.exe is a complex format and not something you're going to extract raw instructions from using a hexdump. What you need is a "disassembler". For Windows I'd recommend x64dbg.

Patch the DayZServer_x64.exe, change "test al, al" to "cmp al, 2". i used x64dbg (https://x64dbg.com) a good video for the whole process: https://drive.google.com/file/d/1F1A0lpumREPXtVeoTMq1HiEnvaZp-NUU/view

Example Network Scanner Scapy

In the last installment we looked at IP headers. One thing you might have seen missing is the port numbers. That's pretty important for making an internet connection. Well it turns out that IP tends to encapsulate other protocols (which is why it has protocol as part of the header). In this article we'll be looking at two popular protocols for internet traffic: TCP and UDP. Before we begin though install scapy which we'll be using to make things easier, and dnslib that will be used during the UDP section:

I've coded my small ARP spoofer in Go because I love the language, though it can very well be coded in other languages, for example Python with Scapy.

Tshark can't do that. The Wireshark app does update its Conversations window pretty frequently when doing a live capture, so that might be a reasonable alternative. Otherwise you could probably also cobble something together yourself with a tool like scapy or some other Python library, but that would clearly be more work.

I don't know if you can do it within the gui, I don't see anything but perhaps a bit of Python code would do it. There is a python library called Scapy that may have functions to help you along the way.
