iPhone users not on iOS 16.1 can now update their handset to iOS 15.7.1. Apple says it “provides important security updates.” It closes almost 20 security holes in the OS.

There’s also iPadOS 15.7.1 that does the same for iPad.

Apple keeps a very tight lid on iPhone security, but that might actually benefit very sophisticated hackers, according to some security experts.

This is how Saudi Arabia was allegedly able to hack Jeff Bezos’s iPhone X.

The accusations Google recently made about iOS security flaws were greatly overstated, deliberately “stoking fear” in iPhone users, according to Apple. The iPhone maker points out that the issues were much more narrow than its rival indicated, and were online for only a brief time.

Google’s Project Zero team said it found gaping security holes in iPhone software that left users exposed to hackers before Apple fixed the flaws earlier this year.

Project Zero released a report on the flaws for the first time Thursday night. The team’s Threat Analysis Group found 14 different exploits that hackers used to gain private data, including photos, messages, contacts and real-time location information from iPhones.
