Adoption rate of iOS 7.0.6 security fix reaches 25.9% within fours days of release

Apple released iOS 7.0.6 on February 21 to patch an SSL security flaw in earlier versions of iOS. The software update was installed on 13.3% of iOS devices within 48 hours and on 25.9% within four days. This increase was steep given the urgent nature of the update, but it did not equal the jump when iOS 7 was launched publicly last year, says analytics firm Chitika, which analyzed online ad impressions from millions of iOS devices on its North American ad network from February 21 to February 25, 2014.

This jump suggests the majority of iPad and iPhone owners will be running the secure version of iOS in just a few weeks. This latest update is being adopted at a faster rate than a similar security update that was pushed out in May 2012. In this case, the 5.1.1 version of iOS was installed on 12 percent of devices within a week and 58% of devices within three weeks of release. The majority of iOS owners, 42.4%, are running iOS 7.0.4, with a small percentage (13.4%) still running iOS 6.

Breaking the issue down by device, iOS 7.0.6 users generate 14.5% of total North American iOS-based Web traffic, with the majority of usage coming from iOS 7.0.4-equipped devices. In terms of major OS versions, more than 84% of iPhone Web traffic within the U.S. and Canada is driven by iOS 7 users.

This rapid adoption rate is not surprising given the importance of the security update. This latest version of iOS patched a flaw in the SSL system that made iOS vulnerable to man-in-the-middle attacks. The flaw was revealed to be an extra “goto” command that caused the OS to skip an important SSL authentication step. A malicious hacker on the same wireless network as iOS and OS X users could hijack the data traffic being sent between the Apple devices and the router.
