Ransomware attacks in June 2024: 128 confirmed incidents

// CONFIRMED RANSOMWARE ATTACKS · MONTH

Ransomnews has confirmed 128 ransomware attacks in June 2024, each one verified against a public source such as a breach notification, regulatory filing, court record or press report. That is 1.3% of the 9,520 confirmed incidents in the dataset. That compares with 114 in May 2024 and 114 in June 2023. The United States accounts for 80 of them (63%), with victims recorded in 22 countries in total. The most affected sector is healthcare, with 27 confirmed victims (21%). Where the operator is attributed, RansomHub leads with 9 confirmed victims. A ransom payment is on the public record in 2 cases and a refusal in 22; the outcome is unrecorded in the remaining 104.

Confirmed ransomware attacks by month, trailing 13 months to June 2024

Every month is a partial count until disclosures stop arriving, which typically takes three to four months. Compare June 2024 with months of the same age rather than with fully matured ones.

Which ransomware groups had the most confirmed victims in June 2024

The operator is attributed in 106 of the 128 confirmed incidents. Counts are confirmed victims, not leak-site claims, so they run well below the totals the groups publish about themselves. Group names link to the live Ransomtracker profile where one exists.

Where the confirmed attacks in June 2024 fall

Country shares carry a reporting bias. United States breach-notification law and SEC disclosure rules push far more incidents onto the public record than most jurisdictions, which makes American attacks easier to confirm and inflates the US share of any confirmed dataset.

Ransom payment outcomes in June 2024

Among the 24 confirmed incidents in June 2024 where the outcome is on the public record, 2 paid and 22 refused, a disclosed payment rate of 8.3%. The remaining 104 carry no public statement either way. Victims that pay have every incentive to stay quiet and public bodies are the most likely to announce a refusal, so treat this as the disclosed rate, not the true one. The ransomware payment rate analysis explains how the disclosed rate has moved since 2018 and how it compares with incident-response firm samples.

Frequently asked questions

How to read this page. Every incident counted here was verified by Ransomnews against at least one public source. Leak-site listings alone do not qualify, because operators inflate, duplicate and occasionally fabricate claims, so these totals are a defensible floor rather than a full census. Records exposed and ransom outcomes appear only where a named source disclosed them. The page is regenerated from the live database, which refreshes weekly.
