Kingdom Come developer Warhorse Studios confirms cyberattack hitting its systems and data

On 27 October 2026, Warhorse Studios — the Prague-based developer behind the Kingdom Come: Deliverance role-playing games — confirmed that it had been the target of a cyberattack. In a public statement, the studio said the incident involved unauthorised access to its company systems as well as access to company data, though it stopped short of detailing exactly what information had been reached.

CEO Martin Frývaldský described the event as "a serious incident for Warhorse Studios and everyone affected," and said the studio's immediate priorities were securing its systems, determining the full extent of the breach, and protecting its employees, partners, and community. Warhorse said it is working with external cybersecurity specialists and is coordinating with the relevant authorities.

What the studio has disclosed

Warhorse has not named a threat actor, said how the intrusion occurred, or confirmed whether any of the accessed data has been published or offered for sale. The studio's acknowledgement that attackers reached company data — rather than merely probing its systems — has fuelled concern that internal, employee, or project information could be exposed, but none of that had been verified at the time of disclosure. Warhorse said it would pause interviews and additional comment while the investigation is ongoing and would share further updates once it could do so responsibly.

Why it matters

Warhorse is one of the Czech Republic's most prominent game developers, and its Kingdom Come: Deliverance series has sold into the millions, making the studio a high-profile target. Game studios hold valuable intellectual property — source code, unreleased builds, and design materials — alongside personal data for staff and business partners, all of which can be attractive to extortion-focused attackers. With the origin, method, and impact of the breach still unconfirmed, the incident's status remains ongoing.
