List of data breaches and cyber attacks in March 2021 – 21 million records breached

Category: Data Breach,Security BreachDISC @ 8:00 am

Don’t be fooled by the fact that we only recorded 20,995,371 breached records in March; it was one of the leakiest months we’ve ever seen, with 151 recorded incidents.

By comparison, there was a seemingly Lilliputian 82 recorded breaches in January and 118 in February.

The issue is that in far more cases than we’d expect, the number of breached records wasn’t included in the notification, so we can’t include it here.

We typically expect ambiguity when it comes to ransomware, because organisations are locked out of their files and can’t calculate what’s been affected. But there were dozens of other cyber attacks and data breaches where the organisation either didn’t know or reveal the extent of the damage.

You can find our full list of incidents below, with those affecting UK organizations listed in bold.
