Warhorse Studios confirms cyber attack, says development hit
The Kingdom Come: Deliverance developer says unauthorized access affected internal systems as anonymous users claim ransomware halted work.
Warhorse Studios confirmed on October 31, 2026, that a cyber attack resulted in unauthorized access to its systems, after first reporting the incident on October 27, 2026, according to Automaton Media. The studio said some internal systems and services were affected and that its investigation is still ongoing.
Warhorse said it will contact affected parties individually. CEO Martin Frývaldský said securing systems, clarifying the full scope of the damage, and protecting employees, partners and the community are top priorities.
Anonymous posts on online forums, including ResetEra and Reddit, claimed the attack involved ransomware that affected all systems and halted IT work, effectively stopping game development. One post said staff were forbidden from even powering on PCs; that post was removed by moderators.
The claims have not been confirmed by the studio. Warhorse has not commented on the specific nature of the attack or on the status of development.
