Ransomware attacks in November 2022: 79 confirmed incidents

// CONFIRMED RANSOMWARE ATTACKS · MONTH

Ransomnews has confirmed 79 ransomware attacks in November 2022, each one verified against a public source such as a breach notification, regulatory filing, court record or press report. That is 0.8% of the 9,520 confirmed incidents in the dataset. That compares with 87 in October 2022 and 79 in November 2021. The United States accounts for 39 of them (49%), with victims recorded in 22 countries in total. The most affected sector is education, with 18 confirmed victims (23%). Where the operator is attributed, Hive leads with 10 confirmed victims. A ransom payment is on the public record in 3 cases and a refusal in 18; the outcome is unrecorded in the remaining 58.

Confirmed ransomware attacks by month, trailing 13 months to November 2022

Every month is a partial count until disclosures stop arriving, which typically takes three to four months. Compare November 2022 with months of the same age rather than with fully matured ones.

Which ransomware groups had the most confirmed victims in November 2022

The operator is attributed in 54 of the 79 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 November 2022 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 November 2022

Among the 21 confirmed incidents in November 2022 where the outcome is on the public record, 3 paid and 18 refused, a disclosed payment rate of 14.3%. The remaining 58 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.
