Keystone confirmed a data breach that compromised names, contact details, shipping addresses and order information, without disclosing the number of people affected. Although the vulnerability was fixed, the exposure of physical addresses enables direct attacks, including kidnapping and physical violence, making the scale of the danger unclear. According to the article, 122 crypto-related physical attacks were recorded in 2026 across 31 countries, with reported losses exceeding $44 million, while Chainalysis estimated losses at more than $100 million as of August. The incident follows a Ledger supply-chain attack exceeding $100 million, a $116 million Coldcard exploit and a data breach at Trezor in August.
