Electronic Voting Debacle
By Scott Granneman, SecurityFocus, The Register

“Right now you can open GEMS’ .mdb file with MS-Access, and alter its contents. That includes the audit log. This isn’t anything new. … Now, where the perception comes in is that its right now very *easy* to change the contents. Double click the .mdb file. … It is possible to put a secret password on the .mdb file to prevent Metamor [a consulting company] from opening it with Access. Being able to end-run the database has admittedly got people out of a bind though. Jane (I think it was Jane) did some fancy footwork on the .mdb file in Gaston recently. I know our dealers do it. King County is famous for it. That’s why we’ve never put a password on the file before.” (Source: “RE: alteration of Audit Log in Access”, support.w3archive/200110/msg00122.html, dated 18 October 2001)
