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

J.S.T. Espana is based in Spain and operates in the Manufacturing sector. Spain ranks #9 worldwide for ransomware disclosures, with 472 victims in this database.

Sector context. Manufacturing companies are frequently targeted because production downtime directly translates to financial loss. Ransomware operators exploit this time-sensitivity to demand higher ransoms and faster payment.

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files are encrypted, so the victim faces two demands at once — pay to restore access, and pay to keep stolen data unpublished.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