Oscars was listed as a victim by the hackers on 5 November, and they are threatening to publish the data they exfiltrated within 20 days as of the time of publishing.

Medusa has not disclosed the volume of the data it has in its possession, but has listed several files as evidence of the hack. These include invoice listings, details of employee work hours, details of events and event contacts, and details of daily takings from various venues. While some documents are several years old, others are dated as recently as November 2025. Also included are several scans of driver’s licences alongside listings of employees’ personal addresses and tax file numbers.
