List of data breaches and cyber attacks in February 2021 – 2.3 billion records breached

You can find March 2021’s list of cyber attacks and data breaches here.

The cyber security industry was rocked in February after a ransomware attack against the Cloud service provider Accellion.

Dozens of organisations that used the software reported incidents in one of the worst months we’ve ever recorded. We found 118 publicly recorded incidents, of which 43 were ransomware attacks.

It’s not the news we were expecting having recently reported that organisations had turned the tide on ransomware attackers – but clearly fraudsters are doubling down on their efforts.

In total, we detected 2,323,326,953 breached records. You can find the full list below, with incidents affecting UK-based organisations listed in bold.
