Tannenhütte

Tannenhütte is an alias used to refer to a hospitality organisation based in Germany. The organisation operates as an inn, providing lodging and hospitality services to guests. Typical services at the inn include accommodation, meals, and beverage offerings. The establishment primarily serves regional travelers and tourists visiting the area. Payment processing at the inn is handled through SumUp, a mobile point‑of‑sale solution.

On 21 March 2025, the innkeeper of Tannenhütte discovered unauthorized access to her SumUp payment service account. The intruder created a linked business account within the SumUp platform linked to the compromised account. This linked account was used to divert all subsequent card payments to foreign bank accounts. After noticing the missing funds, the innkeeper reported the incident to local police. She also contacted SumUp’s customer support to secure the compromised account. In addition, she notified the Irish financial regulator about the fraudulent activity. SumUp later conducted an internal review and subsequently reimbursed the innkeeper for the diverted amount. The reimbursement was characterised by SumUp as compensation, and the company stated it did not accept responsibility for the breach. The incident was reported in a Merkur.de article published on the date of the discovery, which includes a video and Instagram coverage. No further details about the organisation’s size, ownership, or subsidiary relationships are available from the provided sources.
