Institute of Social Security - Paraguay Listed by kairos Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
The Instituto de Previsión Social in Paraguay was listed by the kairos ransomware group on March 10, 2026, after internal files were exfiltrated in an attack whose timing has not been established. Individuals who may have records with the Institute should review their accounts and consider changing passwords or enabling additional verification.
Inside the incident
The listing appeared on March 10, 2026. The number of people affected remains unknown. The only detail released about the data is that internal files were allegedly exfiltrated during a ransomware attack. No further information on timing, method of entry, volume of material or confirmation of the listing has been made public.
The group behind it: kairos
Kairos is a ransomware operator that maintains a public leak site where it lists organizations it claims to have targeted. Such groups commonly encrypt systems and copy data before demanding payment, then publish victim names when negotiations stall. The group’s listing of the Instituto de Previsión Social constitutes an unverified claim; no independent confirmation of the incident has been reported.
About Instituto de Previsión Social
The Instituto de Previsión Social, commonly known as IPS, manages Paraguay’s social security system. It was established by Decree-Law No. 17071 on February 18, 1943. The institution collects contributions from workers and employers and disburses retirement, disability and health benefits. As a result it routinely processes identifying information, employment histories and financial details for a large share of the country’s formal workforce.
What was likely exposed
The only confirmed statement is that internal files were removed. The precise contents of those files have not been disclosed. Organizations of this type typically hold national identification numbers, contribution records, benefit applications and medical or employment data. Without an official inventory it is not possible to state which categories, if any, were included in the exfiltrated material.
The real-world impact
Unauthorized access to social-security records can create long-term risks of identity misuse or targeted fraud, particularly when files contain persistent identifiers such as national ID numbers. For the institution the incident adds operational and reputational pressure at a time when public trust in benefit systems is essential. Both the scale of any harm and the organization’s response remain unknown pending further disclosure.
Were you affected?
Individuals can begin by monitoring official statements from the Instituto de Previsión Social and Paraguay’s data-protection authorities. Practical first steps include:
- Reviewing recent bank and benefit statements for unexpected activity.
- Changing passwords on any online accounts linked to government services.
- Requesting a copy of your personal file directly from IPS where permitted by law.
- Running a free exposure scan of your email address against known breach data sets to see whether your information appears in public listings.

Publicly posted by kairos — unverified claim, pending independent verification
Breach listings — particularly those originating from ransomware or leak sites — are third-party claims that may be unverified, incomplete, or inaccurate. A listing does not by itself confirm that a breach occurred or that any specific data was exposed. Severity is an automated assessment, not a definitive rating. Verification status is shown where available.
Attributions to threat groups and methods reflect public reporting and, in some cases, unverified claims made by the groups themselves; they may be incomplete or later revised.
