If you own an iPhone running iOS 14 or an iPad running iPadOS 14, stop what you are doing and go to Settings → General → Software Update, and update your device to iOS (or iPadOS) 14.4. This is not a feature update; it is a security update that patches three actively exploited zero-day vulnerabilities. You need to do it if you have an iPhone 6 (or later), iPad Air 2 (or later), iPad mini 4 (or later), or iPod touch (7th generation).
As usual, details of the exact nature of the vulnerabilities are sparse, but we know that at least four nation-state-backed advanced persistent threats (APTs) have exploited zero-day iPhone vulnerabilities in the past. Do yourself (and everyone else) a favor and take a minute to update your iPhone and iPad software today.
