Persistent KRONOS malware across my multiple iPhones

In 2021 the bank level malware worm KRONOS was placed on my then iphone 11 reaping havoc and giving the controller the ability to copy over photos, change dates, erase files etc et.The malware has transferred from my iPhone 11 to my 12 pro max 14 pro max and currently 15 pro max, iPad Pro 2022 as well as my Ultra 2 watch. Thousands of dollars worth of equipment that at the touch of a button from some unknown place some a-hole can control everything pretty much on my Apple gear. Tier 2 has told after hours of screen sharing that yes, my 12 pro max and 14 pro max were definitely compromised and told me to seek 3rd party assistance, going so far on the 2nd time I was told this on the 14 pro max to get the fbi involved. The problem with that is every time I fill out an IC3 report (7 now attempts to date) I get through the entire report pass the captcha sign my name and hit send just to have my screen flash real quick and tell me to start over. So basically, notifications to the feds are out. Any suggestions?
