That’s the reason Coinbase’s personal shopper safety posts hold returning to the identical precept: Break the attacker’s tempo. Finish the decision or chat, then confirm independently by means of official channels relatively than utilizing any quantity, hyperlink or “case ID” given to you within the second.
