On July 2, crypto security firm ZenGo identified a double-spend exploit targeting several popular Bitcoin (BTC) wallets, dubbed ‘BigSpender’
Of nine cryptocurrency wallets tested by ZenGo, BRD, Ledger Live, and Edge were found to have been vulnerable to the attack. The three companies updated their products after ZenGo notified them of the threat, however the firm warned that “millions” of crypto users may have been exposed to the exploit prior to its identification.
