St. Nicholas School Listed by 8base Ransomware Group

On February 1, 2025, St. Nicholas School in São Paulo, Brazil, appeared on the leak site of the ransomware group known as 8base. The international school, which serves families across its Pinheiros and Alphaville campuses, is claimed to have had internal files exfiltrated during a ransomware attack. While the exact number of people affected remains unknown, any family connected to the school — current or former parents, students, or staff — now faces the risk that sensitive personal and financial records may be publicly exposed or sold.

Reported Details of the Incident

Public reporting indicates that 8base listed St. Nicholas School on its data leak portal on February 1, 2025. The school, founded in 1980, offers International Baccalaureate programs from elementary through graduate level. According to available information on the ransomware.live tracker, the actors claim to have stolen internal files but have not yet published samples. No precise victim count or detailed inventory of the stolen data has been released by the school or the attackers.

The breach follows the typical 8base pattern of compromising a target, exfiltrating data, and then pressuring the victim to pay to prevent release. As of this writing, it is unclear whether any files have been made public.

Why This Matters for You and Your Family

When a school is breached, the information exposed often includes names, addresses, dates of birth, contact details, medical notes, tuition payment records, and sometimes copies of passports or family identification documents. For parents, this can mean your child’s records, your home address, and your financial information are suddenly at risk. For staff, payroll data and employment contracts may also be included.

Children’s records are particularly concerning because they often contain less mature digital hygiene — shared family emails, reused passwords, or gaming accounts linked to the same address. Once that information surfaces, it can be used to target your family for identity theft, phishing, or physical threats.

The Doxxing and Identity-Chain Risks

Ransomware leaks rarely stop at one dataset. Attackers and opportunistic criminals combine the newly exposed school records with information from earlier breaches to build detailed profiles. A parent’s work email found in the St. Nicholas files can be matched to a password leaked years ago from another service. A child’s name and birthdate can link to a Roblox or Minecraft account. These connections create an identity chain that makes doxxing, account takeovers, and harassment far easier.

Credential leaks like this one cascade into gaming account takeovers and broader doxxing campaigns. What begins as a school breach can quickly expose your family’s entire digital footprint across social media, shopping sites, and online games.

8base’s Publicly Known Track Record

Public reporting attributes 8base with emerging in early 2022. The group has targeted organizations of varying sizes, from mid-market businesses to schools and healthcare providers. Its typical playbook involves gaining initial access through compromised credentials or vulnerable remote desktop services, exfiltrating data before encrypting systems, and then using a double-extortion model: demanding payment to restore systems and a second payment to prevent data publication. The group maintains a leak site where it posts victim names and proof files to increase pressure.

What to do

• Run a DoxxScan to map every link between your family’s emails, phone numbers, usernames, and real-world identities so you can see exactly what the St. Nicholas breach connects to.
• Rotate any password you used at St. Nicholas School or related parent portals anywhere else it is reused, and switch to 2FA through an authenticator app rather than SMS.
• Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next time your information appears it is caught within hours instead of months.
• Cover the entire household with DoxxScan family protection, which includes your children’s gaming accounts that often chain back to the same addresses and family documents exposed in school breaches.
• Let DoxxScan remediation specialists handle takedown requests for any exposed personal information appearing on data broker sites or forums.
