Granville Inn Listed by sinobi Ransomware Group: Ransomware Claim — What’s Alleged & What To Do

Granville Inn, a historic hotel near Columbus, Ohio, was listed on January 11, 2026 by the sinobi ransomware group, which claims to have exfiltrated internal files during a ransomware attack. The number of individuals whose information may be involved remains unknown, as does any confirmation of the data’s contents or the scale of exposure. For guests, employees, or business contacts whose records were stored by the inn, the listing raises the possibility that personal or operational details have moved beyond the organization’s control.

What happened

The incident came to public notice on January 11, 2026, when the sinobi group added Granville Inn to its leak-site listing. The group claims that internal files were removed during a ransomware operation. No further details on the timing of the intrusion, the volume of data taken, or the method of access have been disclosed. The number of people potentially affected is also not stated in available reports.

Inside sinobi

Sinobi is a ransomware operator that maintains a public leak site where it lists organizations it claims to have targeted. Like other groups in this category, it typically exfiltrates data before encrypting systems and then uses the threat of publication to pressure victims. The listing of Granville Inn constitutes the group’s assertion of responsibility; independent confirmation of the claimed intrusion has not been reported.

About Granville Inn

Granville Inn operates as a boutique historic property just outside Columbus, Ohio. It provides 39 guest rooms and suites, hosts weddings, and offers meeting facilities with audio-visual equipment. Organizations in the hospitality sector routinely collect names, contact details, payment information, and identification documents from guests, as well as employment and vendor records. A breach at such a venue can therefore involve data that individuals supplied in the ordinary course of booking accommodations or events.

The information in question

The only category named in connection with the listing is “internal files exfiltrated in ransomware attack.” The precise nature of those files has not been disclosed. Hospitality businesses commonly hold guest registration data, financial transaction records, and internal correspondence; however, whether any of these specific categories are present in the claimed exfiltration remains unconfirmed.

The real-world impact

Individuals whose records appear in the exfiltrated material could face risks of targeted phishing, account takeover attempts, or misuse of payment details, depending on what the files contain. The organization may incur costs related to investigation, notification, and remediation. Because the exact scope remains unknown, both the scale of personal exposure and the extent of any operational disruption are currently unquantified.

Were you affected?

Anyone who has stayed at, held an event at, or worked with Granville Inn can take the following steps while awaiting further official statements:

• Monitor bank and credit-card statements for unauthorized activity.
• Place a fraud alert or credit freeze with the major credit bureaus if financial details were supplied.
• Change passwords for any accounts that used the same credentials as those provided to the inn.
• Watch for official notices from the organization regarding the incident.
