Why it matters

Names, contact details, addresses and order information of 25,964 buyers were exposed, some from 2024, because the promised 180-day data deletion tool did not operate reliably. With the stolen key, anyone can build counterfeit wallets that pass Keystone's own verification, and a buyer who trusts a fake could have crypto stolen. Payment cards, bank details, recovery phrases and private keys were not exposed, but a wave of fake support scams is expected.

What to do

Ignore any Keystone support contact by phone, text, email or mail offering refunds, replacement devices or order fixes, and never share a recovery phrase. Keystone has blocked access, fixed the vulnerability and is emailing affected customers. Buy only through official channels.
