Information about this incident and a simple way to see if you may qualify to be connected with independent attorneys.

What happened

In October 2026, Keystone, the maker of the Keystone crypto hardware wallet (operated by Yanssie HK Limited), disclosed that an attacker exploited a vulnerability in a third-party data monitoring tool to gain access to its official online store. According to the company's disclosures and published reports, the access was detected on October 20, 2026 and confirmed on October 23, 2026. Keystone first disclosed the incident on October 24 and published a fuller report on October 26.

According to published reports, the incident involved approximately 25,964 purchase records from orders placed between 2024 and 2026, plus approximately 12,873 incomplete checkout records. The information involved may include:

  • Names
  • Contact information such as email addresses and phone numbers
  • Shipping addresses
  • Order details

Keystone has stated that recovery phrases, private keys, payment card details and government ID documents were not exposed. Reports also say that the device authentication key used to verify genuine Keystone devices was stolen, and that Keystone plans to destroy 18,835 devices held in inventory and switch to a new key. Some customers have reported that data from older orders was still stored even though the company's privacy terms described automatic deletion after 180 days. Because names, addresses and wallet purchases may be linked, you may want to be cautious about phishing emails, texts, calls or packages that claim to come from Keystone, and never share your recovery phrase with anyone.

As of the date of this page, we are not aware of any lawsuit filed over this incident.
