With this new project I am going to track the biggest data breaches of 2021 extracted from my cyber attack timelines, into an interactive graph with the ability to pinch and zoom the data in the chart area.

The size of the bubble (and the value of the Y-axis) measures the extension of the data breach. In order to make the chart more readable, the scale for both values is logarithmic. The balloon text on each bubble provides additional data about the breach, whose details are also available in the summary table after the chart.

No need to repeat that the data is available from public sources such as blogs and news sites, and please support my work, sharing the content, and of course follow @paulsparrows on Twitter and LinkedIn for the latest updates.

    Hi Paolo,
    thanks for this article!

    One mistake, the link (follow @paulsparrows on Twitter…) to your twitter profile is incorrect! 😉

    Hi Paolo! Really great work on these data! I’m sure I will use your dynamic chart in my next presentations, obviously providing the source. Have a nice day!

      Thanks Franco! Glad you appreciate my work, and most importantly find it useful… You will need a large slide, I predict a large chart…
