Apple’s chipset shipments increased to 18 pc in Q3 globally
Tech giant Apple’s chipset shipments increased to 18 per cent globally in the third quarter this year (from 13 per cent in Q2 2024), due to the launch of its A18 chipset.
With an aim to further strengthen and to fix the existing flaws in the security of iOS, Apple made software upgrades earlier this week and urged its users to update their devices to prevent cyber attacks via iMessages.
The Cupertino-based firm released the upgrades on Tuesday along with a rare note suggesting it was a serious threat.

“One of the major changes in iOS 14 is the introduction of a new, tightly sandboxed ‘BlastDoor’ service which is now responsible for almost all parsing of untrusted data in iMessages,” Samuel Groß, Project Zero, wrote in a blog post on Thursday.
“Furthermore, this service is written in Swift, a (mostly) memory safe language which makes it significantly harder to introduce classic memory corruption vulnerabilities into the code base,” he informed.
He discussed three improvements in iOS 14 affecting iMessage security: the BlastDoor service, resliding of the shared cache, and exponential throttling.
“Overall, these changes are probably very close to the best that could’ve been done given the need for backwards compatibility, and they should have a significant impact on the security of iMessage and the platform as a whole,” the security researcher noted.
“It’s great to see Apple putting aside the resources for these kinds of large refactorings to improve end users’ security,” he added.
The update is for several generations of iPhones and iPads, starting from iPhone 6, reports said.
