- Customers affected include those who signed up to Ledger’s newsletter or receive promotional material.
- Information stolen included email addresses, with a smaller “subset” of 9,500 customers also having their full names, postal addresses, and phone numbers exposed.
- In total, the company estimates around one million email addresses have been stolen.
- Payment information, passwords, and cryptocurrency funds have not been affected.
- The data breach was first detected as part of a bug bounty program on July 14.
- Ledger estimates the data may have been accessed from April until the end of June.
