Deep-Dive: How the Latest iOS Zero-Click Spyware Exploit Bypasses System Sandbox

The technical mechanics of the latest iOS threat notifications reveal a sophisticated multi-stage exploit chain. Attackers transmit maliciously crafted image attachments via iMessage or WhatsApp, triggering heap buffer overflows inside CoreGraphics parsing routines before the user views the message.

Once initial code execution is gained, the exploit bypasses kernel address space layout randomization (KASLR) using a secondary zero-day in the neural processing unit driver. This allows arbitrary code execution inside the root container, establishing persistent command-and-control communication.

Testing demonstrates that Apple's Lockdown Mode successfully mitigates this threat by disabling advanced web features, image preview rendering, and incoming attachment parsing from unknown senders.
