// CONFIRMED RANSOMWARE ATTACKS · MONTH
Ransomnews has confirmed 146 ransomware attacks in February 2023, each one verified against a public source such as a breach notification, regulatory filing, court record or press report. That is 1.5% of the 9,520 confirmed incidents in the dataset. That compares with 96 in January 2023 and 77 in February 2022. The United States accounts for 86 of them (59%), with victims recorded in 28 countries in total. The most affected sector is education, with 28 confirmed victims (19%). Where the operator is attributed, LockBit leads with 26 confirmed victims. A ransom payment is on the public record in 2 cases and a refusal in 35; the outcome is unrecorded in the remaining 109.
Confirmed ransomware attacks by month, trailing 13 months to February 2023
Every month is a partial count until disclosures stop arriving, which typically takes three to four months. Compare February 2023 with months of the same age rather than with fully matured ones.

Which ransomware groups had the most confirmed victims in February 2023
The operator is attributed in 93 of the 146 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 February 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 February 2023
Among the 37 confirmed incidents in February 2023 where the outcome is on the public record, 2 paid and 35 refused, a disclosed payment rate of 5.4%. The remaining 109 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 February 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 February 2023?
Ransomnews has confirmed 146 ransomware attacks in February 2023, each verified against a public source, against 96 in January 2023 and 77 in February 2022. The true total is higher, because many victims never disclose; confirmed counts are a floor, not a ceiling.
Is the February 2023 count final?
It is as settled as a confirmed count gets. February 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 February 2023?
LockBit, with 26 confirmed victims, followed by Black Basta (17) and ALPHV/BlackCat (13). These are confirmed victims, not leak-site claims, counted among the 93 incidents where the operator is attributed.
Which country had the most confirmed ransomware attacks in February 2023?
The United States, with 86 of the 146 confirmed incidents (59%). Germany is next with 16. 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 February 2023?
Education, with 28 confirmed incidents (19% of the total). Government follows with 22, then Healthcare with 20.
What share of ransomware victims paid in February 2023?
Among the 37 confirmed incidents in February 2023 with a public outcome, 2 paid and 35 refused, a disclosed payment rate of 5.4%. 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 February 2023 by records exposed?
Managed Care of North America (MCNA) Dental (Florida, United States, February 2023), with 8,923,662 records exposed according to response.idx.us. 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].
