// CONFIRMED RANSOMWARE ATTACKS · MONTH
Ransomnews has confirmed 50 ransomware attacks in January 2020, each one verified against a public source such as a breach notification, regulatory filing, court record or press report. That is 0.5% of the 9,520 confirmed incidents in the dataset. That compares with 59 in December 2019 and 20 in January 2019. The United States accounts for 36 of them (72%), with victims recorded in 10 countries in total. The most affected sector is government, with 15 confirmed victims (30%). Where the operator is attributed, Maze leads with 5 confirmed victims. A ransom payment is on the public record in 4 cases and a refusal in 18; the outcome is unrecorded in the remaining 28.
Confirmed ransomware attacks by month, trailing 13 months to January 2020
Every month is a partial count until disclosures stop arriving, which typically takes three to four months. Compare January 2020 with months of the same age rather than with fully matured ones.

Which ransomware groups had the most confirmed victims in January 2020
The operator is attributed in 20 of the 50 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 January 2020 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 January 2020
Among the 22 confirmed incidents in January 2020 where the outcome is on the public record, 4 paid and 18 refused, a disclosed payment rate of 18.2%. The remaining 28 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 January 2020 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 January 2020?
Ransomnews has confirmed 50 ransomware attacks in January 2020, each verified against a public source, against 59 in December 2019 and 20 in January 2019. The true total is higher, because many victims never disclose; confirmed counts are a floor, not a ceiling.
Is the January 2020 count final?
It is as settled as a confirmed count gets. January 2020 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 January 2020?
Maze, with 5 confirmed victims, followed by Ryuk (5) and REvil (4). These are confirmed victims, not leak-site claims, counted among the 20 incidents where the operator is attributed.
Which country had the most confirmed ransomware attacks in January 2020?
The United States, with 36 of the 50 confirmed incidents (72%). Canada is next with 3. 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 January 2020?
Government, with 15 confirmed incidents (30% of the total). Education follows with 12, then Healthcare with 7.
What share of ransomware victims paid in January 2020?
Among the 22 confirmed incidents in January 2020 with a public outcome, 4 paid and 18 refused, a disclosed payment rate of 18.2%. 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 January 2020 by records exposed?
Brandywine Urology Network (Delaware, United States, January 2020), with 131,825 records exposed according to healthitsecurity.com. 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.
