Here’s How Signal Broke Into Cellebrite’s Hacking Device

Moxie Marlinspike of Signal wrote on Wednesday how he was able hack into a Cellebrite device. These devices are used by entities like law enforcement to brute force their way into devices like iPhones.

Given the number of opportunities present, we found that it’s possible to execute arbitrary code on a Cellebrite machine simply by including a specially formatted but otherwise innocuous file in any app on a device that is subsequently plugged into Cellebrite and scanned. There are virtually no limits on the code that can be executed.

A fascinating write-up. One can only imagine the thrill of taking a walk, seeing a package fall out of a truck, and finding out that it’s a Cellebrite device.

Signal Signups Surge After WhatsApp Controversy And Elon Musk Tweets

Encrypted messaging app Signal is seeing a surge in signups, The Verge reported. It seems to come on the back of supportive tweets from Tesla chief Elon Musk and controversy around WhatsApp mandating users to share data with its parent company, Facebook.

But what’s happening now appears to be a bit of context collapse on social media, as WhatsApp users think they’re now being forced to share data with Facebook even though that’s been happening all along if they didn’t opt out back in 2016. None of this is helped by Facebook and WhatsApp’s recent attacks on Apple for the iPhone maker’s decision to mandate new self-reported labels on iOS apps and its future plans to force app makers to request permission to track Apple device owners. The new privacy policy notice doesn’t help Facebook’s cause, either, considering it tells users displeased with the changes — which, again, are about how businesses manage their chats on WhatsApp using Facebook’s backend — to “delete their account,” with no other remedies provided.

Private Messenger ‘Signal’ Now Automatically Blurs Faces

Private messenger app Signal added a feature that lets it automatically blur faces in your images.

Thousands of people are protesting against police brutality and to support the Black Lives Matters cause. If you are a part of the protests, you might post photos of the demonstration around you on social media or send them to your friends — and that’s not entirely safe, because it could help identify people there and put them in danger.

A great feature. I’ve been trying to create a shortcut that can obfuscate faces.

It’s Time for Encrypted Messaging app Signal to go Mainstream

Signal creator Moxie Marlinspike is growing the Signal Foundation and adding new features to the app thanks to money from WhatsApp cofounder Brian Acton.

Since then, Marlinspike’s nonprofit has put Acton’s millions—and his experience building an app with billions of users—to work. After years of scraping by with just three overworked full-time staffers, the Signal Foundation now has 20 employees. For years a bare-bones texting and calling app, Signal has increasingly become a fully featured, mainstream communications platform. With its new coding muscle, it has rolled out features at a breakneck speed…

I wish I could use Signal but none of my friends use it.
