According to ransomware.live, 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.
