Ransomware attacks in August 2019: 43 confirmed incidents

// CONFIRMED RANSOMWARE ATTACKS · MONTH

Ransomnews has confirmed 43 ransomware attacks in August 2019, 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 57 in July 2019 and 8 in August 2018. The United States accounts for 37 of them (86%), with victims recorded in 6 countries in total. The most affected sector is government, with 18 confirmed victims (42%). Where the operator is attributed, Sodinokibi leads with 11 confirmed victims. A ransom payment is on the public record in 5 cases and a refusal in 23; the outcome is unrecorded in the remaining 15.

Confirmed ransomware attacks by month, trailing 13 months to August 2019

Every month is a partial count until disclosures stop arriving, which typically takes three to four months. Compare August 2019 with months of the same age rather than with fully matured ones.

Which ransomware groups had the most confirmed victims in August 2019

The operator is attributed in 15 of the 43 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.

  • Dharma1 7%
  • Maze1 7%
  • REvil1 7%
  • Ryuk1 7%

Where the confirmed attacks in August 2019 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 August 2019

Among the 28 confirmed incidents in August 2019 where the outcome is on the public record, 5 paid and 23 refused, a disclosed payment rate of 17.9%. The remaining 15 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.

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 August 2019?

Ransomnews has confirmed 43 ransomware attacks in August 2019, each verified against a public source, against 57 in July 2019 and 8 in August 2018. The true total is higher, because many victims never disclose; confirmed counts are a floor, not a ceiling.

Is the August 2019 count final?

It is as settled as a confirmed count gets. August 2019 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 August 2019?

Sodinokibi, with 11 confirmed victims, followed by Dharma (1) and Maze (1). These are confirmed victims, not leak-site claims, counted among the 15 incidents where the operator is attributed.

Which country had the most confirmed ransomware attacks in August 2019?

The United States, with 37 of the 43 confirmed incidents (86%). Taiwan is next with 2. 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 August 2019?

Government, with 18 confirmed incidents (42% of the total). Education follows with 12, then Healthcare with 9.

What share of ransomware victims paid in August 2019?

Among the 28 confirmed incidents in August 2019 with a public outcome, 5 paid and 23 refused, a disclosed payment rate of 17.9%. 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 August 2019 by records exposed?

CHI Health - Lakeside Orthopedic Clinic (Nebraska, United States, August 2019), with 48,000 records exposed according to the public record. 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.
