Same in my case its Showing Babel, Dnguard and few more.

Pretty sure BEDS is like "Babel, E..., DNGuard, S....." all mixed together.

No, those are mostly fake attributes. It's just a modded cfex. I didn't go further to attempt to deobfuscate it because it lags so much at the cctor part of module when compiling to c#. And it has flood calls when checking via IL which makes it harder to remove all calls that needs to be removed.

I tried to unpack it manually. anti tamper defeated but later calls and it has many invalid assemblies and after that dont work.. it seems it have multi anti tamper module.... and unable to clean the newest version of it....

Try ManagedJiterFr4 on NetBox 4.0;
Plus ConfuserExFixer for removing wrong metadata; some stream left even after removing;
You can't do anything without removing anti-tamper; which currently I can't!

I've found this:
https://github.com/BedTheGod/ConfuserEx-Unpacker-Mod-by-Bed/releases
Is any connection with this?

Hey codecracker, any idea why managedjitter is not working for me even if i run it on netbox 4.0? when i checked on dnspy, error occurs on the part where it checks the pointer values.

[CodeExplorer]

After using ManagedJiterFr4 on NetBox 4.0 some metadata streams got corrupted so I got to restore them;
I've just have to change first method called which is anti-tamper to 062A (a simply return).
For removing invalid streams the strategy is to first set number of streams to a smaller size like 8.
#US with a space at the end (" "); yoi don't seems to be a valid stream!

Here is a partially unpacked exe:
https://www118.zippyshare.com/v/liRTdnBO/file.html
It uses delegates!

you can get it from here:

[Cursedzx]

Finally Fully unpacked!

steps i did to unpack:

1. I ran the application and i dumped it.

2. the anti dump got fixed by anti dump fixer.

3. i used my tool to remove all flood calls.

4. Converted all x86 methods to IL with my tool.

5. Decrypted all Constants with my tool.

6. Used de4dot to clean math mutations and junk Nops.

7. manually Removed Protection calls in Module .cctor.

8. Removed all delegates with @CodeExplorer's Delegate remover.

9. Cleaned junk nops with De4dot again.

10. Removed Proxy calls with TheProxy's Proxy call remover

11. Manually removed all fake/junk classes, attributes, and etc.

12. Renamed functions, methods, assembly, and etc.

13. Manually removed cflow (dont have good cflow remover xd)

if you're asking for the rest of the files that are barely unpacked to study it, just reply xd.

You got to start ManagedJitterFr4 (for Confuser) on NetBox 4.0;
after that just Jit button when the first assembly is logged - first assembly is the main assembly.

When I tried to run app brother, I was continuously getting an error. 

 

and the github link you shared is a confuserex unpacker for normal version by Bed.. 

 

Im using Windows 7 SP1 x86 Architecture and 32 bit Windows. 

 

is it any system incompatiblity?

What is the link of your Cawk Unpacker for normal ConfuserEx one bro? the one you shared on forum, when i try to unpack even normal confuser it always throws error like system.io.exception and close down then..
