Warhorse Studios confirms cyberattack and unauthorised access to company data

Warhorse Studios said in a 30 October update that the cyberattack affected access to some internal systems and services. The studio said it would directly notify anyone affected once it establishes the facts, TwistedVoxel reported.

The update followed Warhorse's first confirmation on 27 October that intruders had accessed company systems and company data without authorisation. The Prague developer said it was working with cybersecurity experts and coordinating with the relevant authorities. Gamereactor reported that the studio had contacted authorities in an effort to track down those responsible.

Chief executive Martin Frývaldský called it "a serious incident for Warhorse Studios and everyone affected." He said the immediate priority was to secure systems, establish the full extent of the breach and protect employees, partners and the community.

What remains unknown

Warhorse has not identified the attackers, the method or a responsible group. It has not specified what data was accessed, including whether employee, partner or player information is involved. The studio says it is still investigating whether personal information was compromised.

Push Square reported that no Warhorse material appeared to have leaked publicly after the disclosure. Tech-insider.org said only unauthorised access has been confirmed, not exfiltration or publication.

Foro3D reported that Warhorse's technical team is reviewing access, credentials and code repositories, while external specialists audit the network.

Why the breach matters

Warhorse is developing two open-world role-playing games: another Kingdom Come instalment and a game set in J.R.R. Tolkien's Middle-earth. Fandomwire reported that the studio announced both in May 2026, has given no release windows and has not officially called the next Kingdom Come title Kingdom Come: Deliverance III.

Foro3D reported that concern centres on design documentation, assets and possible internal builds from the two projects.

Warhorse has not announced changes to either project in connection with the incident, and says operational impact is still being assessed. Fandomwire reported there is no confirmed evidence that either game was compromised or that development cycles will change.

The studio belongs to the Swedish Embracer group, expats.cz reported. Warhorse released Kingdom Come: Deliverance II on 4 February 2025, and Gamereactor reported it sold more than 4 million copies by the end of that year.

What happens next

Warhorse said further updates would be shared as the investigation progresses. It promised additional verified information when it can responsibly share it, and has paused interviews and further comment during the investigation.
