You can also kill the flag via NtQuerySystemInformation, tons of ways to patch IsDebuggerPresent. Can also detour the function and create your own callback to always return false. Patching it with the 3 bytes (more common method) is the easiest, but also the more detected method.

Anybody using IDP probably doesn't know how to detect the patch anyways. Rolling Eyes

Lol true

But it is common to see it as a standard method for protection. Such things like SecurROM use it along with with a virtual debugger attached to the process to 'fake' the DebugPort and make things like Olly unattachable. (Again, can be reset like IDP, not a big deal.)

If you wanna make it an uncrackable password, use a database.

A database wouldn't be good either, you can just remove the check from polling the database for it's information.

Lol, i said uncrackable password not unpatchable program =P

Just because it's stored in a database doesn't mean it wont be uncrackable. Wink

To make it "harden" to be detectable by Olly Debug, just make it as..

Code:

If Text1=label1.caption then...

The label1 must be away from the form.

Dude... are you serious? Do you even know how VB works? No this WILL NOT make it harder for Olly to see, it will be the exact same thing.

And to proove it:

Created a new form, added a textbox and a lable. All default properties. Set the texts to:

Textbox: TextBoxText
Label: LabelCaptionText

Code:

Code:

Private Sub Form_Load()
If Text1.Text = Label1.Caption Then
MsgBox "Matched"
End If
End Sub

Messagebox in there just to say its correct or not, remove it if you want it's not needed nor will it hinder your assumption.

Next, compiled and opened in Olly:

My bad. I trough it where more harden, anyways, i'm not a Olly D. fan =x

Thanks for let me know that i where wrong.
