Who is qilin?

About San Silvestre School
San Silvestre School operates as an educational institution. Organizations of this type maintain administrative systems that store records on students, families, and employees as part of routine operations. A compromise in this setting is consequential because the data often includes persistent personal and academic information that can remain relevant for years.
What data was at risk
The listing refers to internal files exfiltrated in the attack. The exact categories of information contained in those files have not been disclosed. Educational institutions commonly hold contact details, enrollment records, and financial or health-related documentation, but the contents specific to this incident remain unconfirmed.
What's at stake
Individuals whose information appears in the exfiltrated files could see their personal details circulated or misused, leading to follow-on issues such as targeted fraud or unwanted contact. The school may face operational recovery demands, regulatory scrutiny, and the need to notify affected parties under applicable data-protection rules.
Were you affected?
Anyone with a connection to San Silvestre School should treat the listing as a prompt to review their own accounts and take basic protective steps. Public information on the precise records involved is limited, so direct confirmation from the school or official notifications provides the clearest guidance.
- Monitor official communications from the school for any instructions or updates.
- Change passwords on accounts linked to the institution and enable multi-factor authentication where available.
- Run a free exposure scan of your email address against known breach datasets to check for surfaced information.

Publicly posted by qilin — 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.
