Yet another data breach has surfaced.
Swiss Bitcoin Pay, a non‑custodial Bitcoin payment processor, announced it temporarily took its servers offline after detecting a data breach on Monday.
The Neuchâtel‑based firm noted that while customer funds remained secure, email addresses, Bitcoin addresses, IBANs, transaction records, and hashed passwords may have been exposed.
A malicious user has likely gained access to Swiss Bitcoin Pay’s internal systems. As a precaution, we are temporarily shutting down our servers while we investigate and secure our infrastructure.
At this stage, we believe they may have accessed customer email addresses, Bitcoin…

The disclosure follows a series of security incidents affecting Bitcoin and fintech companies. Last week, Revolut revealed that an unauthorized party obtained customer passports, driver’s licenses, verification selfies, and transaction histories, using a spoofed government‑agency email domain to issue fraudulent requests.
Similarly, hardware wallet maker Trezor warned last week that a breach at a third‑party marketing service it relies on for newsletters has enabled attackers to launch phishing campaigns against its users.
“A malicious actor likely infiltrated Swiss Bitcoin Pay’s internal systems,” the company said on Monday. “As a precaution, we have shut down our servers while we investigate and strengthen our infrastructure.”
The company added that user funds remain safe and that any amounts owed to customers will be fully reimbursed.
Swiss Bitcoin Pay did not immediately reply to a request for comment from Bitcoin Magazine.
The firm enables businesses to accept Bitcoin payments swiftly and easily via on‑chain transactions and the Lightning Network.
Data theft has risen throughout 2026. In January, scammers accessed customer information through Ledger’s payment processor, Global‑e, and used it to launch phishing emails.
Last month, crypto wallet provider SafePal disclosed a breach that exposed order information for roughly 39,798 customers, including names, addresses, and purchase details.
