Clearly, this extraordinarily limits performance and could be reenabled by Apple each time you replace to the newest model of iOS.

What’s Apple doing?

For a corporation with probably the greatest safety observe data, Apple has but to acknowledge the BLE flaw that’s being exploited. The explanation might be technical, however many consider Apple just isn’t taking the exploit significantly because it doesn’t pose a large enough menace to customers and/or person privateness. What do you suppose?

In my testing, this assault nonetheless works in opposition to iPhones working iOS 17.2.
