Incident analysis

unyleya.edu.br was listed by Rebornvc ransomware, a group with 3 victims recorded in this database. The listing appeared on the group's leak site on July 8, 2025.

unyleya.edu.br is based in Brazil and operates in the Education sector. Brazil ranks #7 worldwide for ransomware disclosures, with 514 victims in this database.

Sector context. Educational institutions often have under-resourced IT security teams and hold large amounts of student and faculty personal data, making them attractive targets for ransomware groups.

Rebornvc typically follows a double extortion model: data is exfiltrated from the victim's systems before files are encrypted, so the victim faces two demands at once — pay to restore access, and pay to keep stolen data unpublished. The leak site, where this listing appeared, is the lever for the second demand.

Source. Public leak-site disclosures aggregated via the ransomware.live API. The disclosure date is when the listing was published, which can differ from the date of compromise. This site does not publish or link to stolen data. Last updated .
