Thanks. I noticed that the vulnerability existed as far back as 2019.
Apple has long stated that it does not do what Kaspersky claims it does. The iMessage app is sandboxed from all other apps and does not have access to what they claim. There “proofs” are on unlocked, jailbroken iPhones which fully protected iPhones are not the same as what Kaspersky is looking at. They have to jailbreak the devices and run the MIRRORED operating system on an external computer to find what they are claiming. Their own website, which outlines their methodology states this. They cannot get the exploit to work on the device itself.
