Talking E-mail v1.3
Visual Basic 5
Written by McCodEMaN

Introduction

Greetings and welcome to the noble art of reverse engineering!

This is a nice VB program that can read your mail, well..it can read everything you ask it to!
A Visual Basic program are a list of calls to various funktions included in a dll-file. VB5 programs uses a file called: msvbvm50.dll
so if you use softice, make sure that....

EXP=C:\windows\system\msvbvm50.dll

is active in your softice.dat file.
If you don`t have this string you should add it!
To crack VB5 using SoftIce can be fun and there many tricks to use..
but then again there is SmartCheck!!

Tools required

Numega SmartCheck v6.x

Step1 Run Smartcheck and configure the settings, like this:

Under Program/settings menu:

*ERROR DETECTION: Check all boxes except'Report errors immediately'

*ADVANCED SETTINGS: Check the firstfour boxes. The others should be emty!

*REPORTING: All boxes should be checkedexcept the one for:
'Report Mouse Move events from ocx controls'

Step2 OK, now you are ready to fight!

Step3 Load e-talk.exe by click 'File' and 'Open', => open e-talk.exe!

Step4 Run e-talk.exe in SmartCheck by pressing F5 or by pressingthe runbuttom in the
toolfield.

Step5 Ok, now you are going to type in name and a fake serial, i use:
          McCodEMaN & 1234567890,
          the programvalidates the serial and tell you that it was wrong.
          Now terminatee-talk.exe by clicking on the stop buttom.

Step7 Ok, now look through the strings, do you see 'frmTray_Load'?
Good,open it by clicking the ' + ' sign.

Step8 Now go into: 'frmMain_Load ' ,then down and into:'frmNotice.Show'
          Ok, we are insidefrm Notice.Show...were should we go now?
          Yes, into: 'cmdUnlock_Click'.
          Now, go downto: 'txtRegCode.Text'
          Make sure theblue bar is on it!
          Go to "View"and choose: "Show All Events" now you will see almost everything
           that happensinside the program.

Step9 Ok, you are standing on 'txtRegCode.Text' under thisstring you will see one called
__vbaStrMove returns DWORD:4BD140 and if you look in the little windowto
your right,you will see the contents.

"1234567890" (our fake serial)!

Step10 If you go down to: __vbaStrCmp returns DWORD:FFFFFFFF

String1= "UNREGISTERED USER"

String2= "McCodEMaN" (Your username)!

Please Note: I will type a fake serial that represents the valid,because if i type ' X '
instead of the real character it could be hard for you to understand!
So dont bother to try the serial in this essay, i made it up!!!!

Step11 Go down to: __vbaStrCopy returns DWORD:56046C <= "1632-"

Step12 The: __vbaStrMove returns DWORD:48D2C4 <="M"

            Sowe now know that the single: __vbaStrMove between ' Mid$ ' and 'Asc returnsInteger:'
           contains our username. So if this one contains "M" the next should in mycase contain
           "c" and the next after that "C" and then "o" then "d" and so on........

Step13 Go to: Len returns LONG:21 do you see the contens?
Do youknow what this is?.....well, i think you will soon!!!

Step14 Now go down to:

__vbaStrMove returns DWORD:48D2C4 <= "V"

__vbaStrCat returns DWORD:46739C <= Add "V" to "1632-"

__vbaStrMove returns DWORD:46739C <= "1632-V" "1632-"

Step15 Go down to next: Move, Cat, Move.......

__vbaStrMove returns DWORD:56046C <= "+"

__vbaStrCat returns DWORD:4626F4 <= Add "+" to "1632-V"

__vabStrMove returns DWORD:4626F4 <= "1632-V+" "1632-V"

Step16 And next....

__vbaStrMove returns DWORD:56046C <= "G"

__vbaStrCat returns DWORD:46739C <= Add "G" to "1632-V+"

__vbaStrMove returns DWORD:46739C <= "1632-V+G" "1632-V+"

Step17 __vbaStrMove returns DWORD:56046C <= "#"

__vbaStrCat returns DWORD:4626F4 <= Add "#" to "1632-V+G"

__vbaStrMove returns DWORD:4626F4 <= "1632-V+G#" "1632-V+G"

Step18 __vbaStrMove returns DWORD:56046C <= "%"

__vbaStrCat returns DWORD:46739C <= Add "%" to "1632-V+G#"

__vbaStrMove returns DWORD:46739C <= "1632-V+G#%" "1632-V+G#"

Step19 __vbaStrMove returns DWORD:56046C <= "&"

__vbaStrCat returns DWORD:4626F4 <= Add "&" to"1632-V+G#%"

__vbaStrMove returns DWORD:4626F4 <= "1632-V+G#%&" "1632-V+G#%"

Step20 __vbaStrMove returns DWORD:56046C <= "8"

__vbaStrCat returns DWORD:46739C <= Add "8" to "1632-V+G#%&"

__vbaStrMove returns DWORD:46739C <= "1632-V+G#%&8"

"1632-V+G#%&"

Step21 __vbaStrMove return DWORD:56046C <= "2"

__vbaStrCat returns DWORD:4626F4 <= Add "2" to "1632-V+G#%&8"

__vbaStrMove returns DWORD:4626F4 <= "1632-V+G#%&82"

"1632-V+G#%&8"

Step22 __vbaStrMove returns DWORD:56046C <= "Q"

__vbaStrCat returns DWORD:4BCBA0 <= Add "Q" to "1632-V+G#%&82"

__vbaStrMove returns DWORD:4BCBA0 <= "1632-V+G#%&82Q"

"1632-V+G#%&82"

__vbaStrCmp returns DWORD:1

String1 = 1234567890

String2 = 1632-V+G#%&82Q

__vbaFreeStr returns DWORD:0 <= 1632-V+G#%&82Q
