About the Meow group

Meow emerged in 2022 (resurfacing aggressively in 2024), initially operating as a RaaS using the Conti v2 codebase before transitioning to a data-extortion-only model — selling stolen data rather than encrypting files — with a heavy focus on US healthcare and medical research organizations. Meow has listed 145 victims since September 2023.

Incident analysis

River Delta Unified School District was listed by Meow ransomware, a group with 130 victims recorded in this database. The listing appeared on the group's leak site on February 20, 2024.

River Delta Unified School District is based in United States and operates in the Education sector. United States ranks #1 worldwide for ransomware disclosures, with 10,151 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.

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files are encrypted, so the victim faces two demands at once — pay to restore access, and pay to keep stolen data unpublished.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