In the news
Both in the U.S. and abroad, governments are capturing encrypted connections that pass over the public internet and saving them for later use. Such “harvest now, decrypt later” attacks are no longer the thing of science fiction, thanks to post-quantum computers that could meaningfully shorten the amount of time required to unscramble encryption, allowing attackers to read previously private messages.
Such attacks could be more viable within years or decades, so a growing number of organizations are preparing for them with post-quantum encryption. In its recent iOS and iPadOS 17.4 updates, Apple has joined Signal and other online services in offering post-quantum encryption to resist these attacks. Learn more here.

What you can do
- Download your updates! New security features like this underscore the importance of keeping your devices up to date. Check out our guide on the story inside your software updates.
- Note that iMessage is only encrypted between iMessage users, meaning if you are having a “green bubble” conversation with someone on Android, it’s likely using SMS, which is much less secure. And if you or your conversational partner have iMessage backups enabled using iCloud, Apple may have a copy of your messages, with or without these new security features. If these are concerns for you, you and your pals should try out Signal. Read our beginner-friendly guide to Signal.
Updates from my team
- To conclude our spree of guide updates to include Signal’s new username features, we have made some changes to our guide on “Security considerations for confidential tip pages.” Check it out.
- A couple of teammates and I will be at NICAR in Baltimore this week. If you’re around March 7-10, come say hi and get a few FPF stickers!
We are always ready to assist journalists with digital security concerns. Reach out here, and stay safe and secure out there.
Best,
