We've been building up a series of case histories on some of the famous hacks, including Sony, Stuxnet and others. But these are just the tip of the iceberg when it comes to security breaches.
Take a look at Breach Level Index which shows the number data records lost or stolen since 2013. That number at the far left is counting billions. That's more people than are alive in the world.
The site breaks the number of breaches down into different type, industry and regions. Yearly summaries are also available, so take a look at a recent year Records compromised in 2016
While the Breach Level Index gives useful information on the number of breaches that have taken place, it doesn't provide much detail on who has suffered a security breach, nor much information on the size of each breach.
For that we have to go to look at World's Biggest Data Breaches.
Only breaches greater than 30,000 records are shown. The size of the circle is proportional to the size of the loss, so greater the loss, the bigger the circle. Clicking in each circle allows you to access additional information.
From 2004 onwards, a general trend emerges. The number of breaches increase and they tend to be larger. The 92 million records stolen in 2004 seems large, but pales when compared Yahoo and River City Media.
