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 mitigates the damage. Meanwhile, incident response plans might be severely disrupted if the people tasked with handling certain tasks are on leave already.
As tempting as it is to turn our backs on 2022 and look forward to the new year, let’s take a moment to consider the security incidents that occurred, for better or worse, at the back end of last year.
In total, we found 78 publicly recorded data breaches in December 2022, which accounted for 31,586,757 breached records. As always, you can find the full list below, divided into their respective categories.
