Top Data Breaches 2004 - 2021
This week, I found this List of Top Data Breaches 2004-2021 dataset on Kaggle. It listed 295 large data breaches with records breached size from 6,700 to 3B.
My Visualization
The dataset is pretty simple, and the visualization is also starightforward – plot the breaches as points with size denoting the breach size, color denoting breach method, and alongsize year.

Please notice that all the visualizations are designed for desktop view, so it is recommended to view them on a desktop device.

Insights
- The Yahoo data breach in 2013 is by far the largest data breach, and the only one leaked over 1B of records;
- Over half of the breaches are caused by hacking, but there are also ~30% of the breaches being caused by poor security, lost or stolen.
