WHY PATCHING WHILE SERIAL NUMBER IS FISHY


LockBox v1.0.1
A Cracking Tutorial
by ASTAGA [D4C/C4A]


ABOUT THE PROGRAM 

LockBox is a program that will allow you to store confidential 
information onyour computer, in an encrypted file that is pro
tected by a user password.  Use it to store your web site pass
words, credit card information, ordering information, etc.  
If more than one person uses your computer, each user can
have their own copy of the program and each can secure their 
own information.

LockBox uses two encryption techniques to insure that your info
rmation is secure. It encrypts and decrypts using the 256-bit 
version of TwoFish (created by the team led by Bruce Schneier, 
author of the famous Blowfish algorithm). The encryption and 
decryption are performed using keys generated by Elliptic Curve 
public key encryption. This technology features 160-bit
key length -- roughly equivalent to 1024-bit RSA.

HOW TO FISH SERIAL NUMBER by USING SOFTICE


1.  Run the program, click REGISTER button and keyed-in fake
    reg code = 73881050

    Do not click OK button yet.


2.  Load SoftIce and create a new breakpoint : 

	bpx hmemcpy
	Press F5

3.  Click OK button now, and you'll break in SoftIce again.
    Press F11 once and press F12 several times until you see
    this below snippet codes.

	Break due to BPX KERNEL!HMEMCPY
	Break due to G 
 	bd  *   [enter] 
	: BPX 015F:0044C302  [enter] 
	: Press F10 2 times and display EDX register,  your fake reg code 
        appear in the Data Window at virtual address 0167:00C134D8  .
	: BPM 0167:00C134D8   [enter] 
	: Press X or F5


    You'll break again in SoftIce and see these below snippet codes :

	_________________________________________________________________

	Break due to BPMB #0167:00C134D8 RW DR3 
	Press F10  once
	: ? ecx  [enter]
	: 38383337  0943207223  "8837"  ==> part of your fake code

 			         0167:00C1AEE0 . Write down this potential 
                             reg code.  Scroll up one line above you 
                             will see your own product ID ( in my case 
                             is 5565-5841-9770-4015 ) . 
	: bd *
	: F5  to return to registration dialog box


4.  Repeat registration procedures, and keyed-in  0170-1920-7875-7537 
    as your registration code. 
    You're registered. 


5.  Where the hell is my registration info is stored ??

	-  The correct registration code is stored in the HKCR and HKLM
	   registry as follows ( before it's registered ) :

REGEDIT4

[HKEY_CLASSES_ROOT\CLSID\{DD9633C1-FBE4-11D3-AA01-444553540010}]

[HKEY_CLASSES_ROOT\CLSID\{DD9633C1-FBE4-11D3-AA01-444553540010}\ProgID]
@="008FFC"

[HKEY_CLASSES_ROOT\CLSID\{DD9633C1-FBE4-11D3-AA01-444553540010}\Mask]
@="6E5A4D08"

REGEDIT4

[HKEY_LOCAL_MACHINE\Software\CLASSES\CLSID\{DD9633C1-FBE4-11D3-AA01-444553540010}]

[HKEY_LOCAL_MACHINE\Software\CLASSES\CLSID\{DD9633C1-FBE4-11D3-AA01-444553540010}\ProgID]
@="008FFC"

[HKEY_LOCAL_MACHINE\Software\CLASSES\CLSID\{DD9633C1-FBE4-11D3-AA01-444553540010}\Mask]
@="6E5A4D08"




6.  How can I practise with another registration key ?

	-  I strongly recommended you not to do this !


END NOTES

   This program is sold as shareware, so you can try before you buy.  
   This is convenient for you, saves expenses by dispensing with all 
   that packaging, and cuts out the middle person.  So it is cheap, 
   but it is not free.  
   If you like the program, and you will, be sure to register and pay.
   To keep shareware prices low,  users must do the right thing: 
   Register, pay up, and smile/grin at yourself in the mirror.

   Do not distribute your crack release based on this tutorial, because
   you become a LAMER(s)!!!!!!!!
   ( tHATDUDE (PC97) defined LAMER(s) is the guy who sits in front of
   personal computer, using Hex Editor, ripping off other group(s)
   crack release, repacking (distro) them under his name. 
   Adopted from newsgroup alt.cracks, alt.crackers - February 1997 ) 

    More about LAMER(s):
	lamer /n./ [prob. originated in skateboarder slang]
	Synonym for luser, not used much by hackers but common among warez 
	d00dz, crackers, and phreakers. Oppose elite. Has the same connota
	tions of self-conscious elitism that use of luser does among 
	hackers.
