When Tapes Go Missing

Presented at DEF CON 15 (2007), Aug. 3, 2007, 4 p.m. (50 minutes).

We hear it in the news all too frequently, "26 IRS tapes containing taxpayer information potentially contain taxpayers' names, SSNs, bank account numbers, or employer information", "tapes containing customer information were stolen from a lock box... 196,000 names, SSN, etc", "disappearance of 9 tapes containing payroll information on 52,000 employees, including SSNs and in some cases bank account numbers. The 9th tape contained "less sensitive" information about 83,000 hospital patients." With quotes such as "It is important for customers to note that these tapes cannot be read without specific computer equipment and software", in attempted damage control, it is critical that we understand when such statements are true and under what circumstances they are not. With this in mind, we will take a look at the little investigated field of tape forensics. We will look at how easy it is to recover data from tape, the limitations of tape data recovery and tape data recovery methods, and of course, steps to protect your company data.
