Swiss Crypto Firm Pocket Bitcoin Exposes 5411 Customer Records in Security Incident

Pocket Bitcoin recently disclosed that its August security incident exposed additional personal and financial information involving 5,411 customers. The company said two distinct groups were affected, with one containing bank transaction lists for 5,120 customers and the other covering correspondence from 291 customers.

The larger group included customer names, residential addresses, transfer amounts, and dates of transactions, as well as in some cases, IBAN account numbers. The smaller group involved correspondence Pocket Bitcoin sent to partner banks, which exposed potentially sensitive records including names, postal addresses, public Bitcoin addresses, identity document copies, and source-of-funds records.

Pocket Bitcoin emphasized that its core databases and customer Bitcoin remained unaffected by the incident, and that attackers did not compromise private keys. The company has notified regulators in Switzerland and Liechtenstein and filed a police report, but it currently sees no indication of misuse.
