This article reads a bit weird. The report itself is linked: https://www.lookout.com/threat-intelligence/report/q3-2024-mobile-landscape-threat-report-copy

But as the article says, it's mainly saying iPhones fell to phishing attacks twice as often. But that isn't about the phone or OS it's about the users, and I am in no way surprised that iOS users fall to phishing attacks more often.
