Security Challenge 3 - Activation

This is the third in a series of security challenges.

These are designed to show ways of making Access apps reasonably secure.

 

1. The application is an ACCDE file so all VBA code has been removed.

   The file has been renamed as a runtime file (ACCDR). It will not run if the file type is changed.

2. Startup properties have been modified e.g. shift bypass disabled. It will not run if this is re-enabled

   There is no access to the navigation pane, ribbon, options menu or the rest of the application window

   The taskbar and all desktop items are also removed. These are restored automatically when the

   application is closed using the Quit button

3. Mouse movement is confined within the active form

4. The app is password protected and the password is NoDBG. It will not run if this is altered or removed

5. No changes are made to your computer by running this app. There are no restrictions on the number of

   times it can be run

 

The challenge is intended to be solvable.

Solving it will require some different methods to those used in the previous challenges

Once again the app includes 'special tables' - both read only and deep hidden

 

The app contains 3 forms - the first form is shown in the screenshot

At first the Click Me button will be disabled, locked and hidden.

 

The other 2 forms CANNOT be opened directly

 

The main parts of the challenge are to:

a) find out how to show/enable/unlock the Click Me button on the main form

b) change the properties of a read only table and modify its contents

c) use VBA functions to obtain various info and use this to generate an ActivationID specific to your workstation

 

The challenge is intended to be solvable without hacking.

Indeed trying to hack it will probably make it harder to solve.

Follow the clues provided in this thread and the challenge itself

 

HINT: Solving this may be easier on certain computer systems. Hence difficulty level = 3.5 stars overall

 

You may need to search online for solutions to certain parts of the challenge

 

I hope you enjoy puzzling out this challenge.

 

If you succeed, please follow the supplied instructions to provide feedback by email (or use the feedback form provided).

Please include the answers to a, b & c together with how you solved the challenge and the approximate time taken. Screenshots may be useful

 

NOTE: Access databases, including this one, can NEVER be made 100% secure

A capable and determined hacker can break any Access database given time
