SlowMist Chief Information Security Officer 23pds posted a tweet to remind users to pay attention to the latest attack case on Apple ID, in which a malicious phishing program appeared in Apple Store, which stole user accounts and passwords by imitating normal applications. Then the attacker added his own number to the trusted number of two-factor authentication to control account permissions and bypass Apple's 2FA. "Cryptocurrency users must pay attention, because many users and wallets currently use iCloud backup as the backup solution. Once attacked, it may cause asset losses."
