Thanks romero


I am always amazed by the fighting spirit of those tools developers


in the end, someone steals the Code like what happened with yck Confuser and starts selling it :o


really a shame...

Confuser is opensource. Eazfuscator is freeware, that's a preetty big difference. :)


BTW, who tried to sell Confuser? Got link?

I lost the link now, I hope yck will post it here


looks like a lamer stole the code and built a new GUI and now selling the CODE :o

It seems they are too slow to process the report...

Meanwhile, I really appreciate his effort to make it 'good-looking' and remove the copyright infohuh.gif, but it seems he forgot to remove the copyrights in Confuser.Injection.dll...


Confuser is licensed under GPL, he can modify it but he should release the source as well...I am very disappointed.sad.gif

ehhe ,) yep if he uses your stuff he should make it open source too .. but in the end your confuser will rule so or so ;)

i had recently such a target




found the strings decrypt method .. but it doesnt work with sae

so u would have to write ya own tool



whoknows had a little look inside too .. heres the method



u have to fix the string function...


find a init method as


Me..Name =   .(-102829684)


and go there------^^^

mmm yes I fix mannualy... I must write something to automate the decription...

SAE should work just fine, if you enable only string decryption.

If you want, you can patch PublicKeyToken and then all SAE options should work just fine. See here: http://forum.tuts4you.com/topic/26729-eazfuscatornet-protected-target/

I have just try this with SAE 1.14.2 on Eaz 3.1 but it don't decrypt the strings,

I read the topic that you have linked

thank you

Choose "String & Flow" as your profile when deobfuscating.

Crystal this technique is not decrypt strings. perhaps it work with older versions of Eaz.
