Data Breaches and Cyber Attacks in Europe in February 2024 – 50,884,709 Records Breached

IT Governance Europe’s research found the following for February 2024:

Europe saw significantly fewer records breached in February than in January: a 98% drop, after a 2-PB breach on Russian research centre Planeta.* However, there was a significant rise in the EU: a 273% increase.

Both Europe and the EU also saw a big rise in the number of publicly disclosed security incidents: 90% and 212% increases respectively. This is despite a global drop in incidents over the same period.

This month, there were two outlier incidents in Europe, one in terms of the amount of data breached, and one in terms of the number of organisations affected:

  1. Viamedis and Almerys, which suffered a breach affecting more than 33 million people. We elaborate below.
  2. supply chain attack that affected 100 Romanian hospitals – specifically, via their healthcare management system, Hipocrate Information System.

*For incidents where we only know the file size of the data breached, we use the formula 1 MB = 1 record. Given that we can’t know the exact numbers, as it depends on the types of records included (for instance, pictures and medical histories are considerably larger files than just names and addresses), we err on the side of caution by using this formula. We believe that this underestimates the records breached in most cases, but it is more accurate than not providing a number at all.
