Paul,
This recreation just demonstrates how you can recreate this situation. The
problem is that Microsoft Access stores the password to the database in
plaintext. Without knowing the password beforehand, one can search other
mdb's looking for table attachments orginiating from the passworded
database. The commercial product from FMS has been compromised, and a
number of others (including our own product).
