Each dot represents the location of a ransomware attack, with the size of the dot depicting the number of records impacted. 
This map updates weekly and pinpoints the locations of each ransomware attack in the US, from 2018 to present day. Where available, it includes the ransom amount, whether or not the ransom was paid, the entity and industry that was targeted, and the strain of ransomware used. Our researchers search through state reports, industry news, and cybersecurity databases to find the latest ransomware attacks on US businesses, healthcare organizations, educational institutions, and government agencies.

In our industry-specific reports, we found:

2022 key findings

According to the publicly-reported ransomware attacks collated by Comparitech researchers, 2022 saw:

  • 381 attacks–half the amount recorded in 2021 (680)
  • An average ransom demand of $4.15 million–over one million less than the average demand in 2021 ($5.5 million)
  • 22,256,986 records impacted–a vast reduction on 2021’s total of 43.6 million
  • An average of 105,483 records impacted per attack–slightly less than 2021’s average of 115,318


Our researchers have searched through state data breach sites, cybersecurity reports, high-authority news articles, and extensive cybersecurity databases to collate this list of ransomware attacks. Where possible, we have only included the names of companies that have been confirmed by relevant authorities or companies. This is the same for ransoms that have or have not been paid. Some may assume an entity has paid a ransom after data disappears from a hacker’s website, however, we do not make this assumption.

From April 1, 2023, we have also logged unconfirmed ransomware attacks posted on hackers’ websites. In these cases, we omit the company name until we can confirm the attack.
