List of data breaches and cyber attacks in May 2020 – 8.8 billion records breached

We have just seen 8,801,171,594 breached data records in one month. Yes, 8.8 billion.

Granted, the majority of those were the result of a leaky database belonging to the Thai phone network AIS that was quickly resolved – but it was a dire month even if you discount that. There were 105 incidents in total, including several that are alarming either in terms of their size or their severity.

Indeed, it bears reminding relatively small breaches can often be the most damaging – such as an email gaffe this month in which the identities of 250 abuse survivors in Northern Ireland were exposed.

Take a look at every data breach and cyber attack that we recorded in May in this blog. As always, incidents affecting UK organisations are listed in bold.
