On October 9, 2014 ice cream chain Dairy Queen confirmed that nearly 400 store locations had customer credit and debit card data compromised by computer malware. Dairy Queen has more than 6,300 restaurants worldwide with 4,500 franchised stores in the United States. This data breach affected nearly 9% of U.S. stores.
SigActs assembled data on each breached location and created an interactive map to visualize the extent of the intrusion.
While network intrusions and data breaches may seem like abstract concepts, they involve pieces of tangible equipment and data that is stored on physical hard drives. There are important geospatial dimensions to this type of attack, and seeing breached locations on a map can help an analyst recognize patterns and trends related to an intrusion.
Dairy Queen is based in Edina, Minnesota and owned by Warren Buffett’s Berkshire Hathaway Inc. The company is offering customers free identity repair services; details are available in a corporate press release on the data security incident.
