Trying to be secure... You deleted the app. You turned on disappearing messages. You did everything right. The FBI can still read your Signal messages. Huh? This wasn't a Signal failure. Signal did its job. iOS didn't. The phone was storing notification previews in a database long after the app was gone, because someone turned on Lock Screen message previews. Apple just patched it in iOS 26.4.2, and they only found out about it because a defendant's court case exposed it during testimony. 🔎 This is why privacy promises and privacy architecture are two different things 📲 Update your phone. Not because you're hiding something. Because your phone is quietly keeping receipts you don't know about. ⚠️ And if you're a CISO still telling employees that "just use Signal" is a complete privacy answer, it's time to revisit that conversation. https://www.macrumors.com/2026/04/22/ios-26-4-2-notification-database-security-fix/ #Cybersecurity #Privacy #iOS #InfoSec #Leadership #security #cloud #infosec #AlwaysUpdate
