List of data breaches and cyber attacks in December 2021 – 219 million records breached

2021 was a difficult year many of us, and with the hope that COVID-19 will dissipate in the spring, this is a new year more than any other where we want to look forwards, not backwards.

But before we turn our attention to 2022, we must first round out 2021 with our final monthly review of data breaches and cyber attacks. December saw 74 publicly disclosed security incidents, which accounted for 219,310,808 breached records.

You can find the full list of incidents below, with those affecting UK-based organisations listed in bold.

Additionally, we’ll also soon be publishing our latest quarterly review of security incidents, in which you can discover the latest trends and take a look back at the year as a whole.
