A different way to monitor the cyber threat is to measure it by counting the number of records breached. This method gives a better sense of scale and only includes successful attacks by definition. The chart to the right shows the cumulative number of records breached in cyber-attacks over the last 15 years based on data from the Identity Theft Resource Center (idtheftcenter.org).
When cyber criminals hacked the WIFI network of a Minnesota store and stole the details of 94 million credit cards from TJ Maxx in 2007, people were shocked by the scale of the breach. But as the chart shows, that breach has paled into insignificance when compared to the scale of the recent events such as the 1.3bn email records (4) breached when the spam operator River City Media was hacked in 2017.
