That is 0.8% of the 9,520 confirmed incidents in the dataset. That compares with 114 in June 2023 and 60 in July 2022. The United States accounts for 39 of them (50%), with victims recorded in 23 countries in total. The most affected sector is government, with 13 confirmed victims (17%). Where the operator is attributed, LockBit leads with 15 confirmed victims. A ransom payment is on the public record in 2 cases and a refusal in 13; the outcome is unrecorded in the remaining 63.

Confirmed ransomware attacks by month, trailing 13 months to July 2023

Every month is a partial count until disclosures stop arriving, which typically takes three to four months. Compare July 2023 with months of the same age rather than with fully matured ones.

Which ransomware groups had the most confirmed victims in July 2023

The operator is attributed in 56 of the 78 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.

  • LockBit15 27%
  • ALPHV/BlackCat12 21%
  • Rhysida6 11%

Where the confirmed attacks in July 2023 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 July 2023

Among the 15 confirmed incidents in July 2023 where the outcome is on the public record, 2 paid and 13 refused, a disclosed payment rate of 13.3%. The remaining 63 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.

Largest confirmed ransomware attacks in July 2023 by records exposed

Record counts are recorded only where a named source disclosed them, which is the minority of cases, so this table ranks disclosed impact rather than true impact.

Frequently asked questions

How many ransomware attacks were confirmed in July 2023?

Ransomnews has confirmed 78 ransomware attacks in July 2023, each verified against a public source, against 114 in June 2023 and 60 in July 2022. The true total is higher, because many victims never disclose; confirmed counts are a floor, not a ceiling.

Is the July 2023 count final?

It is as settled as a confirmed count gets. July 2023 ended more than four months before the latest database refresh, so most late disclosures have arrived, though a confirmation can still be added whenever a new public source surfaces. The figure is recalculated from the live database on every load.

Which ransomware group had the most confirmed victims in July 2023?

LockBit, with 15 confirmed victims, followed by ALPHV/BlackCat (12) and Rhysida (6). These are confirmed victims, not leak-site claims, counted among the 56 incidents where the operator is attributed.

Which country had the most confirmed ransomware attacks in July 2023?

The United States, with 39 of the 78 confirmed incidents (50%). France is next with 4. Part of the gap is exposure and part is reporting: US breach-notification and SEC disclosure rules put more incidents on the public record than most jurisdictions.

Which sector was hit most by ransomware in July 2023?

Government, with 13 confirmed incidents (17% of the total). Healthcare follows with 13, then Education with 12.

What share of ransomware victims paid in July 2023?

Among the 15 confirmed incidents in July 2023 with a public outcome, 2 paid and 13 refused, a disclosed payment rate of 13.3%. Most victims never state whether they paid, and those who pay have the least reason to say so, so the disclosed rate understates real payment behaviour. The payment rate analysis tracks this figure since 2018.

What was the largest ransomware attack of July 2023 by records exposed?

McLaren Health Care (Michigan, United States, July 2023), with 2,192,515 records exposed according to therecord.media. Record counts exist only where a source disclosed them, so this ranks disclosed impact.

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. Cite as: Ransomnews Confirmed Ransomware Attacks Dataset, ransomnews.com, with a link to this page. Bulk access and methodology questions: [email protected].
