CONFIRMED RANSOMWARE ATTACKS · COUNTRY

Ransomnews has confirmed 54 ransomware attacks in Taiwan between August 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 0.6% of the 9,715 confirmed incidents in the dataset. So far in 2026, 15 have been confirmed, against 16 in 2025 and 3 in 2024. The most affected sector is manufacturing, with 36 confirmed victims (67%). Taipei is the city with the most confirmed victims, at 25.

No ransom payment is on the public record; a refusal is recorded in 3 cases and the outcome is unrecorded in the remaining 51.

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.

Which ransomware groups attack organisations in Taiwan most

The operator is attributed in 48 of the 54 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 Taiwan fall

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 51 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 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.
