| elmasmalo1 05. Jun 2015 | Still trying to understand few things, there is SOOO much code obfuscation, it really makes it difficult. This is my reversing log just in case any other person would like to know some stuff, if it ever helps. QXUQKZ.pYXzSR() : Void //Has the current (Form1) AYqGAp.ePDIfq() : Void //Has the Registered Form ON pYXzSR(): Bunch of buttons, probably to prevent reversers to find the button that handles the serials and stuff! Only 2 Textboxes, This is what we want! Me.XgilGY(New TextBox) Me.SDZPaZ(New TextBox) Jackpot??? QXUQKZ.mMAnma(): Routine checks if Serial is valid? QXUQKZ.sKwmgz() : TextBox (Serial TextBox) and it's assigned by XgilGY(TextBox) : Void This is so far what I have... it's 1:48 AM Need to take a rest :D @RDG, Tell me how I'm doing. |

| elmasmalo1 05. Jun 2015 | Ahah, thanks, :D I really see how easy it is for a professional like you, but I'm starting :D - Thanks for the compliment :D, also did you hard coded your obfuscation or you used a 3D party software? I'm really intrigued it is really amazing |

| Matteo 08. Jun 2015 | seems interesting, i have not downloaded it but i can give you a tip (i hope) why don't you try a .NET deobfuscator? for example DeSmart (which should be used for smart assembly) it will rename everything for you in field1, field2... which is much better than QXUQKZ |
| elmasmalo1 10. Jun 2015 | I know, I've tried running a generic symbol renamer I found online, but I left the assemly corrupted :D |
