Description
On December 11, 2022, H-Hotels AG suffered a cyberattack that disrupted its IT infrastructure, prompting immediate containment measures. The hospitality group, operating 60 hotels across Germany, Austria, and Switzerland under brands including Hyperion, H4 Hotels, and H.ostels, detected unauthorized access by cybercriminals who bypassed its technical and organizational security systems. Internal and external IT specialists confirmed the breach as a professionally executed attack. In response, H-Hotels disconnected all IT systems from the internet to prevent further spread of the intrusion, causing significant communication limitations. While hotel operations and guest bookings remained functional, staff could not receive or respond to customer emails, leading the company to advise contacting properties directly by phone. H-Hotels filed a criminal complaint with German investigative authorities and engaged IT forensic experts to examine compromised systems, a process expected to take several days before systems could be cleansed and verified as secure.
The Play ransomware group claimed responsibility for the attack on December 19, 2022, listing H-Hotels on its Tor leak site and alleging theft of private data including client documents, passports, and identification materials. However, the threat actors provided no evidence to substantiate these claims. H-Hotels maintained throughout its communications that forensic investigators found no evidence of data exfiltration as of December 11, though it committed to notifying affected parties if subsequent investigations revealed personal data leaks. The company coordinated with data protection authorities regarding potential GDPR implications, given the risks of exposing guest booking details, financial information, and travel itineraries. Restoration efforts prioritized securing systems against repeat attacks while maintaining partial operational continuity across its 9,600-room portfolio employing 2,500 staff. Public updates were restricted during the investigation, with the organization directing stakeholders to its website for official information.
