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.

    Here’s the latest updates regarding breach at third-party provider exposes medical information of US healthcare patients on 6th July.

    A data breach at a third-party provider has potentially exposed the private medical information of patients at Northwestern Memorial HealthCare (NMHC) providers.

    Unknown actors gained unauthorized access to a database owned by Elekta, which provides a cloud-based platform that handles legally-required cancer reporting to the State of Illinois.

    In a security advisory, the healthcare provider, based in Chicago, said that the attackers made a copy of the datasets, which include patient names, dates of birth, Social Security numbers, health insurance information, and medical record numbers.

    The database also contained clinical information related to cancer treatment, including medical histories, physician names, dates of service, treatment plans, diagnoses, and/or prescription information.

    Hi paolo! this is impressive to a beginner like me.
    I would like to know if you used any automated tools for data collection or did you compile them by hand.

      For the moment the process is manual, but I have some plans for the future…

    Hi Paolo, Indeed very good work. Thanks for all the effort you put in and sharing the data! I am quoting and referencing your work.
    Could you please confirm that you are using ISO2A country code?

    1. Paolo Passeri

      Thanks Sandhya. Yes I use the ISO2A country code, but there might be some corrections (for example I use UK instead of GB).

    Uhm, interesting. It’s sad all this happened in just three months. Those are too many breaches. Security is still too weak, or malicious hackers are too strong. That’s not good.

    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…
