St Catherine of Siena Listed by Sinobi Ransomware Group

On October 8, 2025, the sinobi Ransomware Group added the Catholic community of St. Catherine of Siena to its public leak site, claiming that internal files had been exfiltrated during a ransomware attack on the organization.

What Public Reporting Shows

Public reporting indicates the group posted details of the incident on its onion-site leak page, accessible via ransomware.live. The entry lists St. Catherine of Siena as a victim and states that internal files were successfully exfiltrated. No specific count of affected individuals has been disclosed, and the precise volume or types of records remain unclear beyond the general description of internal files. The community, which describes itself as committed to living out Christ's commandments to love God and neighbor, appears to have been targeted in a typical ransomware operation involving both encryption and data theft for extortion.

October 8, 2025 marks the public listing date. As with many ransomware cases, the group likely gave the organization a payment deadline before releasing the sample data or threatening full publication.

Why This Matters for You and Your Family

When a community organization like a parish or school suffers a breach, the personal information of ordinary families often sits inside the stolen files. Donation records, volunteer lists, family contact details, children's enrollment forms, and staff directories can all be exposed. If you or your family attend St. Catherine of Siena or similar local institutions, your phone numbers, addresses, email accounts, or dates of birth may now be in attackers' hands. These details rarely stay isolated; they become building blocks for identity theft, phishing campaigns, or harassment directed at you at home.
