Ransomware attacks in France: 503 confirmed incidents, 2018 to 2026

// CONFIRMED RANSOMWARE ATTACKS · COUNTRY

Ransomnews has confirmed 503 ransomware attacks in France between January 2018 and August 2026, each one verified against a public source such as a breach notification, regulatory filing, court record or press report. That is 5.3% of the 9,520 confirmed incidents in the dataset. So far in 2026, 16 have been confirmed, against 37 in 2025 and 34 in 2024. The most affected sector is government, with 125 confirmed victims (25%). Paris is the city with the most confirmed victims, at 80. Where the operator is attributed, LockBit leads with 48 confirmed victims. A ransom payment is on the public record in 1 case and a refusal in 127; the outcome is unrecorded in the remaining 375.

Confirmed ransomware attacks in France by year

The current year is a partial count. Confirmation lags the attack itself, so recent months keep filling in after the fact; read a low figure for the latest year as incomplete rather than as a decline.

Which ransomware groups attack organisations in France most

The operator is attributed in 334 of the 503 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 France fall

Ransom payment outcomes in France

Among the 128 confirmed incidents in France where the outcome is on the public record, 1 paid and 127 refused, a disclosed payment rate of 0.8%. The remaining 375 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 France 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 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.
