Incident analysis

Vanderbilt EDU was listed by Byod ransomware, a group with 25 victims recorded in this database. The listing appeared on the group's leak site on November 9, 2026.

Vanderbilt EDU is based in United States and operates in the Education sector. United States ranks #1 worldwide for ransomware disclosures, with 10,480 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.

Byod 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files are encrypted, so the victim faces two demands at once — pay to restore access, and pay to keep stolen data unpublished.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 .
