Answer:
denial-of-service attack
Step-by-step explanation:
A denial-of-service (DoS) attack occurs when legitimate users are unable to access information systems, devices, or other network resources due to the actions of a malicious cyber threat actor. Services affected may include email, websites, online accounts (e.g., banking), or other services that rely on the affected computer or network. DoS attacks can cost an organization both time and money while their resources and services are inaccessible.
Berryhill Finance suffered from a denial-of-service attack. They kind of shot themselves in the leg by shutting down the site and opening it to those they thought were legitimate. As a result, many of Berryhill's customers were unable access the site, unable to obtain loans, causing Berryhill to lose a significant amount of business.
