Ransomware attacks in June 2020: 94 confirmed incidents

// CONFIRMED RANSOMWARE ATTACKS · MONTH

Ransomnews has confirmed 94 ransomware attacks in June 2020, each one verified against a public source such as a breach notification, regulatory filing, court record or press report. That is 1% of the 9,520 confirmed incidents in the dataset. That compares with 95 in May 2020 and 31 in June 2019. The United States accounts for 44 of them (47%), with victims recorded in 26 countries in total. The most affected sector is manufacturing, with 13 confirmed victims (14%). Where the operator is attributed, Maze leads with 31 confirmed victims. A ransom payment is on the public record in 3 cases and a refusal in 9; the outcome is unrecorded in the remaining 82.

Confirmed ransomware attacks by month, trailing 13 months to June 2020

Every month is a partial count until disclosures stop arriving, which typically takes three to four months. Compare June 2020 with months of the same age rather than with fully matured ones.

Which ransomware groups had the most confirmed victims in June 2020

The operator is attributed in 67 of the 94 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.

Most active groups by confirmed victims

  • Maze31 46%
  • Pysa14 21%
  • REvil8 12%

  • NetWalker3 4%
  • Sekhmet2 3%
  • Ako1 1%

Where the confirmed attacks in June 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 June 2020

Among the 12 confirmed incidents in June 2020 where the outcome is on the public record, 3 paid and 9 refused, a disclosed payment rate of 25%. The remaining 82 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 June 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 June 2020?

Ransomnews has confirmed 94 ransomware attacks in June 2020, each verified against a public source, against 95 in May 2020 and 31 in June 2019. The true total is higher, because many victims never disclose; confirmed counts are a floor, not a ceiling.

Is the June 2020 count final?

It is as settled as a confirmed count gets. June 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 June 2020?

Maze, with 31 confirmed victims, followed by Pysa (14) and REvil (8). These are confirmed victims, not leak-site claims, counted among the 67 incidents where the operator is attributed.

Which country had the most confirmed ransomware attacks in June 2020?

The United States, with 44 of the 94 confirmed incidents (47%). Canada is next with 8. 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 June 2020?

Manufacturing, with 13 confirmed incidents (14% of the total). Technology follows with 12, then Government with 11.

What share of ransomware victims paid in June 2020?

Among the 12 confirmed incidents in June 2020 with a public outcome, 3 paid and 9 refused, a disclosed payment rate of 25%. 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 June 2020 by records exposed?

Metropolitan Community College of Kansas City (Missouri, United States, June 2020), with 638,186 records exposed according to kctv5.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. Cite as: Ransomnews Confirmed Ransomware Attacks Dataset, ransomnews.com, with a link to this page. Bulk access and methodology questions: [email protected].
