Apple Continues Security Updates for iPhone 6s, Addressing Critical Vulnerability
Apple has released security updates for a range of older iPhones and iPads, including the iPhone 6s from September 2015, to address a critical vulnerability known as Coruna. This move demonstrates Apple’s ongoing commitment to security, even for devices that are over a decade old.
The Coruna Vulnerability
The Coruna vulnerability, which affected devices running iOS 13 through iOS 17.2.1, combined five iOS exploits with 23 vulnerabilities. Apple has now released patches for the following system versions:
- iOS 15.8.7
- iPadOS 15.8.7
- iOS 16.7.15
- iPadOS 16.7.15
The primary motivation behind these updates is to protect devices that, due to hardware limitations, cannot be upgraded to newer iOS versions. As of iOS 17.3, systems are protected against this vulnerability, but Apple’s action indicates that a significant number of users are still operating older versions.
Affected Devices
The following devices are included in this security update:
- iPhone 6s
- iPhone 6s Plus
- iPhone 7
- iPhone 7 Plus
- iPhone 8
- iPhone 8 Plus
- iPhone X
- iPhone SE (1st generation)
- iPad mini 4
- iPad Pro 9.7″
- iPad Pro 12.9″
- iPad (5th generation)
Google’s Discovery and Attack Vectors
Apple’s swift response was prompted, in part, by a report from Google detailing ongoing attacks targeting older iOS systems. Experts have also noted the vulnerability was exploited using methods similar to hacking software reportedly used by governments. Infections occurred through fake cryptocurrency services redirecting users to compromised websites.
Apple’s Commitment to Long-Term Support
Apple’s continued software support for older devices, even those considered “vintage” by industry standards, sets it apart from many Android manufacturers. While Android devices often cease receiving updates after a few years, Apple provides security patches for older iPhones and iPads, even if they cannot receive major operating system upgrades. This commitment is particularly notable for the iPhone 6s and 6s Plus, which were released in September 2015 – nearly eleven years ago as of March 2026.
Apple specifically states that this update “provides an important security fix and is recommended for your iPhone.” Users with any of the affected devices are strongly encouraged to install the update as soon as possible.
