high severity September 30, 2023 · 4 min read Unverified claim — what this is

Motel One Listed by alphv Ransomware Group

If you are a customer of Motel One, here’s what is being claimed, and what it would mean for you.

Motel One is a German hotel chain. It was founded in 2000 by the former Accor manager Dieter Müller in Munich and is now run by him and his wife, Ursula Schelle-Müller.

— from Alphv’s own leak-site posting. This is the group’s claim, quoted verbatim; it is not GalaxyWarden’s reporting and has not been independently verified.
Motel One Listed by alphv Ransomware Group

On September 30, 2023, German hotel chain Motel One appeared on the leak site operated by the alphv ransomware group. The listing states that internal files were exfiltrated during a ransomware attack, although the exact number of records affected and the specific data types contained in those files remain undisclosed by the group.

Reported Details from the Listing

The alphv leak site entry, still accessible via its onion address as of the initial publication, claims successful data exfiltration from Motel One’s systems. No ransom demand figure is published, nor does the listing specify which internal documents were taken. The disclosure indicates that Motel One, founded in 2000 in Munich by Dieter Müller and now operated with his wife Ursula Schelle-Müller, was targeted in a ransomware incident. Public mirrors of the leak site, such as ransomware.live, state the September 30, 2023 posting date and the group’s assertion that sensitive corporate files are now in their possession.

Internal files exfiltrated is the only description provided; whether the material includes customer booking records, payment details, employee information, or operational spreadsheets is not stated in the primary disclosure.

Why This Matters for You and Your Family

When a hotel chain like Motel One suffers a breach, anyone who has ever stayed at one of its properties or used its online booking system could have personal information at risk. Even if the precise contents are unknown, ransomware groups routinely obtain guest names, addresses, email addresses, phone numbers, dates of stay, and sometimes payment card details. If your family has traveled in Europe and chosen Motel One for its modern, affordable rooms, your information may now sit in an attacker’s archive.

Hotel booking data often links directly to real-world identity because reservations frequently include passport numbers, home addresses, and contact details required for check-in. A single leak can therefore serve as the foundation for broader identity theft, phishing campaigns, or fraudulent travel bookings made in your name.

The Doxxing and Identity-Chain Risk

Exfiltrated internal files frequently contain more than isolated records. They can include spreadsheets that connect guest emails to booking references, employee directories, vendor contracts, and internal correspondence. Attackers and subsequent data resellers can use these connections to map relationships between online handles, phone numbers, and physical locations. Once such links exist, opportunistic criminals stitch them into doxxing profiles that expose family members, including children whose names may appear on family bookings or loyalty accounts.

Credential leaks that surface in these incidents often cascade into account takeovers on travel platforms, email services, and gaming networks. A child’s gaming account tied to a parent’s breached email can quickly become part of the same identity chain, leading to harassment, swatting, or further extortion attempts.

Alphv’s Known Track Record

Public reporting attributes the alphv ransomware group, also known as BlackCat, with emerging in late 2021. The gang has since claimed responsibility for attacks on dozens of organizations across multiple countries, including healthcare providers, manufacturing firms, and retail chains. Their typical playbook involves initial access through phishing or exploited remote desktop protocols, followed by rapid lateral movement, data exfiltration, and deployment of custom ransomware.

After encryption, alphv operators usually wait a short period before publishing samples or full datasets on their leak site if the victim does not pay. The group has repeatedly demonstrated willingness to release sensitive corporate and customer data, applying pressure through both encryption and public exposure. Exact success rates and total victims remain difficult to quantify, but industry trackers consistently list alphv among the most active ransomware operations of the past two years.

What to do

  • Run a DoxxScan to map every link between your email addresses, phone numbers, travel booking accounts, and real-world identity, with cleanup handled by specialists.
  • Rotate any password you used on the Motel One booking site or loyalty program anywhere else it is reused, and immediately enable 2FA through an authenticator app rather than SMS.
  • Enable continuous DoxxScan monitoring across 13.1B+ breach records and 100+ platforms so the next exposure of your data is caught and acted upon in hours, not months.
  • Cover the entire household with DoxxScan family protection that extends to dependents and children’s gaming accounts, which often chain back to the same breached email or address.
  • Let remediation specialists manage takedown requests for any exposed personal documents or broker listings that surface from this or linked incidents.

The alphv listing of Motel One is a reminder that travel and hospitality companies remain high-value targets whose compromises directly affect ordinary guests and their families. Staying ahead requires more than reactive checks; it demands ongoing visibility into how your information travels across the internet. DoxxScan by GalaxyWarden delivers that visibility through continuous monitoring across 13.1B+ breach records and 100+ platforms, AI-powered identity-chain mapping, hands-on remediation by specialists, and full household coverage that includes children’s gaming accounts at risk of cascading takeovers.

Unverified claim — what this report is
This page documents a public listing on a ransomware/extortion group’s leak site, tracked via public threat-intelligence sources. A listing is the attacker’s claim. GalaxyWarden aggregates and reports such claims; we have not independently verified that a breach occurred, what data (if any) was taken, or the accuracy of anything the group asserts, and the named organisation has not necessarily confirmed the incident. Sections above describe what the listing shows and the group’s documented history — not verified findings about the named organisation. If you represent this organisation and believe anything here is inaccurate, tell us and we’ll review it promptly.
