The reasons the company gives

The company's own explanation, not something inferred from the numbers.

Because AI may enable conventional attacks to be conducted in greater volume and at greater speed, increasing the risk that unpatched vulnerabilities and configuration flaws will be exploited before they are addressed. The series of public disclosures concerning unauthorized access incidents in Japan was also cited as a reason.
