Confirmed ransomware attacks in Portugal 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.

Ransom payment outcomes in Portugal
Among the 11 confirmed incidents in Portugal where the outcome is on the public record, 0 paid and 11 refused, a disclosed payment rate of 0%. The remaining 32 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 many ransomware attacks in Portugal have been confirmed?
Ransomnews has confirmed 43 ransomware attacks in Portugal since August 2018, including 5 so far in 2026. Each one is verified against a public source such as a breach notification, regulatory filing or press report. The true total is higher, because many victims never disclose; confirmed counts are a floor, not a ceiling.
Which ransomware group is most active in Portugal?
LockBit, with 5 confirmed victims, followed by Hive (3) and Play (2). These are confirmed victims, not leak-site claims, counted among the 27 incidents where the operator is attributed.
Which sector is hit most by ransomware in Portugal?
Government, with 15 confirmed incidents (35% of the total). Healthcare follows with 10, then Education with 5.
Which cities in Portugal have the most confirmed ransomware attacks?
Lisbon (15), Coimbra (3), Porto (3), Loures (2), Ponta Delgada (2). City is recorded where the victim organisation is headquartered or the incident was reported, so distributed organisations are counted once.
How often do ransomware victims in Portugal pay the ransom?
Among the 11 confirmed incidents in Portugal with a public outcome, 0 paid and 11 refused, a disclosed payment rate of 0%. 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 is the largest confirmed Portugal ransomware attack by records exposed?
TAP Air Portugal (Lisbon, Portugal, August 2022), with 115,000 records exposed according to bleepingcomputer.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.
