Confirmed ransomware attacks in Taiwan 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 Taiwan
Among the 3 confirmed incidents in Taiwan where the outcome is on the public record, 0 paid and 3 refused, a disclosed payment rate of 0%. The remaining 50 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 Taiwan 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 in Taiwan have been confirmed?
Ransomnews has confirmed 53 ransomware attacks in Taiwan since August 2018, including 14 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 Taiwan?
Crazy Hunter, with 5 confirmed victims, followed by LockBit (3) and The Gentlemen (3). These are confirmed victims, not leak-site claims, counted among the 47 incidents where the operator is attributed.
Which sector is hit most by ransomware in Taiwan?
Manufacturing, with 35 confirmed incidents (66% of the total). Healthcare follows with 7, then Technology with 3.
Which cities in Taiwan have the most confirmed ransomware attacks?
Taipei (25), New Taipei City (7), Hsinchu (6), Taoyuan City (3), Kaohsiung City (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 Taiwan pay the ransom?
Among the 3 confirmed incidents in Taiwan with a public outcome, 0 paid and 3 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 Taiwan ransomware attack by records exposed?
GlobalWafers Co., Ltd. (Hsinchu, Taiwan, June 2024), with 10,780 records exposed according to taipeitimes.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.
