The 100 Biggest Data Breaches of 2017
Commercial firms often hit the headlines for security breaches, but governments lose data just as often. In the chart below, we’ve plotted the hundred largest data breaches of 2017 in terms of the number of records leaked. They’re sorted by month, with larger circles showing bigger breaches. Governmental leaks are in pink, and other sectors are shown in green.
The largest breach of 2017 was from a commercial firm: in March, a faulty backup at spam giant River City Media exposed the email addresses of an astonishing 1.4 billion people. But the second and third largest breaches were both from governments. In May, the Motor Vehicles Department in Kerala, India, leaked the registration details of 20 million vehicle owners, and in June, a data analytics firm that helped Donald Trump’s 2016 election campaign exposed personal information on 198 million Americans.
