List of data breaches and cyber attacks in December 2022 – 31.5 million records breached

December can be the best or worst time to suffer a data breach. On the one hand, people have started to wind down to the end of the year, all attention is on the holidays and a data breach is more likely to fall under the radar.

But for the very same reasons, a December data breach can be the worst possible scenario. Your team suddenly has a mountain of work on its hands as it mitigate the damage.
