Is Network Traffic Data Better than Gold?

The theft of credit card and personal identity information is big business. We’ve all seen the headlines about data breaches at Target, Home Depot, and JPMorgan Chase.

The theft of this personal information is not only expensive to JPMorgan Chase (and its insurers), and not only upsetting for all the people impacted—it can also lead to more cyber attacks in the future, since personal information helps cybercriminals better target individuals.

Where did they go, and what did they take once they got inside?
