Misericórdia de Santo Tirso Listed by qilin Ransomware Group: Ransomware Claim — What’s Alleged & What To Do
Misericórdia de Santo Tirso was listed by the qilin ransomware group on June 16, 2026, following the exfiltration of internal files in a ransomware attack that affected an undisclosed number of people. Individuals connected to the organisation should check whether their information was exposed and take any recommended protective steps.
The listing of Misericórdia de Santo Tirso on a ransomware group's leak site on 16 June 2026 illustrates the continued pressure ransomware operators place on organisations that hold sensitive personal and operational records. Public information remains limited to the claim of a listing and the statement that internal files were exfiltrated; no confirmed count of affected individuals or detailed timeline of the intrusion has been released.
Inside the incident
On 16 June 2026 the qilin ransomware group listed Misericórdia de Santo Tirso on its leak site. The only details made public are that internal files were allegedly exfiltrated during a ransomware attack. The number of people affected, the precise date of the intrusion, the volume of data taken, and any ransom demand or payment status remain undisclosed.
Who is qilin?
Qilin is a ransomware-as-a-service operation that has been publicly active since at least 2022. The group typically gains initial access through compromised remote-access services or phishing, deploys encryption, and exfiltrates data before demanding payment. Its operators have previously claimed responsibility for incidents against entities in healthcare, local government and manufacturing sectors. In this case the group claims to have obtained files from Misericórdia de Santo Tirso; no independent confirmation of the claim has been published.
About Misericórdia de Santo Tirso
Misericórdias are longstanding Portuguese charitable institutions that deliver social care, residential support for older people, and limited health services. These organisations routinely process personal data including medical histories, financial information for means-tested benefits, and records of family circumstances. A breach at such an entity is consequential because the data supports ongoing care for vulnerable populations and because legal obligations around confidentiality are strict under Portuguese and EU data-protection rules.
What data was at risk
The only confirmed detail is that internal files were allegedly exfiltrated. The exact categories of information contained in those files have not been disclosed. Organisations of this type commonly hold personal identifiers, health records, and administrative documents; however, whether any of those specific categories were among the files taken in this incident remains unconfirmed.
The real-world impact
Individuals whose records may have been copied face the possibility of identity misuse or unwanted disclosure of sensitive personal circumstances. For the organisation, the incident adds operational strain at a time when it must investigate the scope of access, notify regulators if required, and restore systems while continuing to deliver care. No evidence of subsequent misuse of the data has been reported publicly.
Were you affected?
Because the number of individuals involved is unknown, anyone who has received services from Misericórdia de Santo Tirso should treat their information as potentially at risk. Practical first steps include monitoring bank and benefits statements for unusual activity, enabling multi-factor authentication on important accounts, and remaining alert to unsolicited contact that references personal details.

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.
