Crypto Wallet Maker Ledger Loses 1M Email Addresses in Data Theft

Ledger said customer details have been stolen in a data breach that may well have been exploited for over two months.

• In a note to clients Wednesday, CEO Pascal Gauthier said the French hardware wallet provider fell victim to a large-scale data breach from an unauthorized third party.
• The hacker, whose identity remains unknown, gained access to Ledger's e-commerce and marketing database.
• Customers affected include those who signed up for Ledger's newsletter or to 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.
• A Ledger spokesperson confirmed to CoinDesk the data breach has now been fixed.
• The wallet provider has now alerted the French authorities and is filing a complaint with the public prosecutor.
• Ledger said it has not found customer information disseminated online nor has it received any ransom demands.
