Apple released the first iPhone Rapid Security Response update, called iOS 16.4.1(a), on May 1. The company recommends the update for all users, and it applies some important security fixes on iPhones, including two issues that can be actively exploited. .
One of the security issues may expose sensitive user information to third parties, and another issue may allow third parties to execute commands on your device without your knowledge.
To download the update, go to Settings > General > Software Updatetap Install Now and follow the onscreen prompts.
Some users have seen an error message when installing iOS 16.4.1 (a) on their devices. The message read, “Could not verify Security Response,” and said they were no longer connected to the internet. If you see this error message, you can try downloading the update again or try again later.
Rapid Security Response updates are a new type of device update introduced by Apple iOS 16.2 in December. According to Apple, Rapid Security Response updates provide users with important security fixes more frequently. These updates help you mitigate iPhone security issues in real time, instead of waiting for the release of a larger iOS update. Rapid Security Response updates are designated with a letter to distinguish them from other updates.
Apple did not immediately respond to CNET’s request for comment.
