Security researchers spoke to CoinDesk about how users can protect themselves after Monday’s breach.
What to know : Ledger, the maker of one of the most popular hardware wallets in crypto, confirmed Monday that a trove of customer data was exposed in a breach linked to its third-party payment processor, Global-e, sending fresh waves of concern through the crypto community. While Ledger says private keys, wallet funds and payment information were not accessed, the incident exposed the names and contact details of users who purchased devices through its online store, reigniting long-standing fears about recurring data leaks and the real-world risks they can create. Security researchers warn that similar campaigns following past Ledger leaks have led to wallet takeovers, financial losses and, in some cases, concerns about physical targeting in so-called “wrench attacks.”
