Online security


Published on

Presentation given at the April 14, 2011 MacPeople Macintosh Users Group. A massive data breach at Episolon compromised the names and email addresses of customers of many major U.S. companies. If you do business with Best Buy, Wallgreens, TiVo, Chase, Target or a host of other companies, you have probably been impacted. We expect to see very targeted "spear phishing" attacks come out of this data breach in the near future. We'll talk about the seriousness of the breach, what precautions you need to take now that this data is out and how you can keep yourself safe from these types of breaches in the future.
