Confirmed ransomware attacks in Argentina 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 Argentina
Among the 14 confirmed incidents in Argentina where the outcome is on the public record, 0 paid and 14 refused, a disclosed payment rate of 0%. The remaining 29 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 Argentina have been confirmed?
Ransomnews has confirmed 43 ransomware attacks in Argentina since July 2020, including 1 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 Argentina?
LockBit, with 5 confirmed victims, followed by Play (4) and Akira (3). These are confirmed victims, not leak-site claims, counted among the 36 incidents where the operator is attributed.
Which sector is hit most by ransomware in Argentina?
Government, with 15 confirmed incidents (35% of the total). Healthcare follows with 6, then Utilities with 5.
Which cities in Argentina have the most confirmed ransomware attacks?
Buenos Aires (27), Chaco (2), Cordoba (2), Resistencia (2), Rio Negro (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 Argentina pay the ransom?
Among the 14 confirmed incidents in Argentina with a public outcome, 0 paid and 14 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.
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.
