Just got a security alert from Lifelock that may be of interest . I'll cut/paste it below.
Update to iOS 14.4 immediately to address critical vulnerabilities
What is happening?
Apple released iOS 14.4 for iPhones and iPadOS 14.4 for iPads to address three critical vulnerabilities in its mobile operating systems that may already be actively targeted by hackers. The vulnerabilities target the kernel, the core of iOS, and WebKit, the web browser engine behind Safari.
You can read about the specifics of the vulnerabilities on Apple's Support site.
What should I do about it?
If you have any of the following iOS or iPadOS devices:
iPhone 6s and later
iPad Air 2 and later
iPad Mini 4 and later
iPod Touch (7th generation)
You should update your operating system to iOS 14.4 or iPadOS 14.4 immediately by following Apple’s instructions for iPhones and iPads.
