According to PANews on November 29, ZachXBT, a chain detective, reminded users to strengthen account and fund security. He said that Yubico (security key), Proton (mail service) and Tutanota (mail service) are currently offering discounts. Proton supports Bitcoin payments, while Tutanota can use Monero (XMR) to purchase gift cards through its official partner ProxyStore. In addition, some products of hardware wallet brands Trezor and Ledger are also on sale.

ZachXBT recommends that users avoid using Gmail or SMS 2FA (two-factor authentication) and switch to security keys or hardware wallets to store funds as soon as possible. He emphasized that security devices should be purchased through official channels to prevent security risks caused by counterfeit products, and reminded users that many security incidents are completely preventable.
