Data Breaches and Cyber Attacks in the USA in February 2024 – 621,095,066 Records Breached

IT Governance USA’s research found the following for February 2024:

  • 322 publicly disclosed security incidents (45% of all incidents globally)
  • 621,095,066 records known to be breached

This month, globally, 719,366,482 records were known to be breached – 86% of them were in the USA.

This is unusual. Typically, the USA suffers more incidents than any other country, but these tend to lead to a disproportionately low number of records breached.

This month is different due to two outlier breaches:

  1. Zenlayer’s publicly exposed database, which contained 384,658,212 records
  2. Pure Incubation Ventures, which allegedly* had 183,754,481 records go up for sale

*The threat actor provided 100,000 records as a sample.

Top 5 biggest breaches

Note 1: Where ‘around,’ ‘about,’ etc. is reported, we record the rounded number. Where ‘more than,’ ‘at least,’ etc. is reported, we record the rounded number plus one. Where ‘up to,’ etc. is reported, we record the rounded number minus one.

Note 2: For incidents where we only know the file size of the data breached, we use the formula 1 MB = 1 record. Given that we can’t know the exact numbers, as it depends on the types of records included (e.g. pictures and medical histories are considerably larger files than just names and addresses), we err on the side of caution by using this formula. We believe that this underestimates the records breached in most cases, but it is more accurate than not providing a number at all.

Sector overview

For our monthly analyses, we just look at the top 5 most breached sectors in the USA by number of incidents and by known number of records breached.
