Tutorial Cracking : Folder Access v2.0.0
|
Target : Folder Access v2.0.0
Tool : OllyDebug DeFixeD
Hex Workshop v5.02
Pengenalan Target :
Folder Access has a very easy to use interface and the security of your data is always a mouse click away which is integrated with windows explorer context menu so all you have to do is right click a folder and click on Lock Folder menu option or to unlock click on UnlockFolder menu option.
Basa Basi :
Sebetulnya program ini free version alias gratis cuma dibatasi dalam penguncian folder sebanyak 4 folder.
Bila lebih dari 4 folder akan muncul peringatan.
"In free version you cannot lock more than 4 folders. Would you like to purchase Folder Access?".
Diprogramnya banyak tulisan "Free Version".
Langsung ke TKP :
Buka file PdfWiz.exe dengan OllyDebug DeFixeD.
Di "CPU - main thread, module folderAc".
Klik kanan "Search for" trus "All Referenced Text Strings".
Geser keatas terus klik kanan pilih "Search For Text".
Pada "Enter Text to Search For" masukkan kata "you cannot lock more than 4 folders", hilangkan tanda di case sensitive dan tandai entire scope.
