At long last here are the slides from my Notacon talk.  Below is an overview of the talk:

Notacon Mythbusters: Is Personal Data Stored on Hotel Keys? Using Magstripe Analysis Tools to Discover the Answer

For years emails and rumors have circulated that personal information such as credit card numbers, names and addresses are stored stored on hotel room keys.

The talk starts with an introduction to magstripe cards and how information is encoded onto the cards. The next section discusses what tools can be used to read and analyze magstripe cards. Next we test the myth by looking at data collected from a large number of hotel keys to determine what personal information is stored on them. The talk concludes with a discussion of advanced magstripe analysis, data manipulation techniques and how these techniques can be used during penetration tests and security assessments.

On a related note I hope to get back into updating this blog. One of my first priorities is to finish up the series on magstripe analysis. Thank you for reading and stay tuned for more updates!
