Keystone says website breach exposed hardware wallet buyers’ addresses

Hardware wallet manufacturer Keystone suffered a cybersecurity breach that compromised sensitive customer shipping data. The exposed database includes delivery addresses and contact details of individuals who purchased cryptocurrency storage devices online. Security researchers immediately raised alarms, noting that physical addresses combined with known crypto holdings create severe safety risks. Threat actors frequently exploit such databases to orchestrate sophisticated phishing campaigns or physical extortion attempts against wealthy holders. The incident underscores ongoing supply chain and data protection vulnerabilities within the broader digital asset hardware sector.
