Colegio Notre Dame Campinas Listed by thegentlemen Ransomware Group

On April 27, 2026, Colégio Notre Dame Campinas appeared on the leak site of the ransomware group known as thegentlemen. The Brazilian private Catholic school, which serves families from kindergarten through secondary education in the Campinas region of São Paulo, is claimed to have had internal files exfiltrated during a ransomware attack. While the exact number of affected individuals remains unknown, any family connected to the school — whether as current or former parents, students, or staff — now faces the possibility that personal information once held by the institution is in the hands of criminals.

What Public Reporting Shows

Public reporting indicates that thegentlemen posted evidence of the breach on their leak site, referencing both notredamecampinas.com.br and a ZoomInfo business listing for the school. The school, founded in 1961 by the Congregation of Holy Cross, employs between 51 and 200 people and maintains an active Instagram presence with more than 12,000 followers. Available reporting describes the incident as a ransomware attack in which internal files were successfully exfiltrated. No specific deadline for payment has been publicly detailed in the initial postings, but the listing itself signals that negotiations either failed or were never initiated.

Why This Matters for You and Your Family

When a school’s internal files are stolen, the information exposed often includes names, addresses, phone numbers, dates of birth, and sometimes financial or health details of students and their parents. For ordinary families, this is not an abstract corporate risk. It is your child’s school records, your home address, and your contact information now circulating among threat actors who specialize in turning stolen data into profit. Even if you are no longer connected to the school, records from past enrollments can remain in backup systems for years. The breach therefore touches current families, alumni households, and anyone whose data was stored in the school’s networks.

The Doxxing and Identity-Chain Implications

Ransomware groups rarely stop at publishing a single file dump. Once initial data appears, it frequently feeds into broader doxxing chains where attackers or opportunistic criminals link email addresses, phone numbers, and usernames across dozens of platforms. A parent’s email tied to a school portal can be cross-referenced with social media, gaming accounts, or shopping profiles, rapidly building a complete identity profile. This is precisely why credential leaks like this one cascade into account takeovers. Children’s gaming accounts, often secured with the same family email or a simple password, become especially vulnerable entry points for further harassment or extortion.

The Gentlemen’s Publicly Known Track Record

Public reporting attributes thegentlemen with emerging in the ransomware ecosystem in recent years. The group has targeted organizations across multiple countries, focusing on schools, healthcare providers, and mid-sized businesses. Their typical playbook involves gaining initial access through common vectors such as phishing or unpatched remote desktop services, followed by exfiltration of sensitive files before deploying encryption. They then demand payment to prevent publication, using leak sites to apply public pressure. While exact prior victim counts fluctuate in open sources, the group has maintained a consistent pattern of listing education-sector targets when ransom demands go unmet.
