We knew 30 years ago that message attachments (mostly email at that time) were a huge security problem. All those binary file types to parse... what could go wrong ;)

It's good to see Apple's Lockdown mode having such success by simply disabling message attachments.

One would hope there would be some sanitization of attachments to prevent this.

I also wish there was a regular option in iOS Messages to disable link previews.

I know you're not being serious, but for anyone who may not realize that, it does more than disabling attachments. Lockdown Mode's "optional, extreme" protection substantially changes the experience of using your device. https://support.apple.com/en-us/105120
