The GrapheneOS team has said that “France isn’t a safe country for open source privacy projects,” pointing to what it describes as the expectations of encryption backdoors.

Last week, it announced it has removed all servers from France.



1/5
This raises some questions: what is GrapheneOS, why do people use it, and what's up with France? 🇫🇷

For the first question: GrapheneOS is a nonprofit, open-source, and Android-based operating system used by many people seeking better privacy, security, & control.

2/5
It offers no bloatware, Google lock-in, forced apps, or background data collection, as well as advanced privacy & security.

GrapheneOS has also begun to end its relationship with hosting provider, OVHCloud.

There are open questions on if OVH can guarantee data sovereignty.

Security researchers say a design flaw in WhatsApp’s contact-lookup feature has enabled what they call the “largest data leak in history”, exposing billions of phone numbers without breaking encryption.

Normally the lookup process would incur rate limits, normally...

1/5 Image
But in this case, they were able to run through 7k phone numbers /second (and session), using 63bn numbers generated by their tool.

None of this required decrypting a single message.

They confirmed 3.5bn phone numbers, more than the number officially stated by WhatsApp.

2/5
More than 57% of the active accounts they grabbed had a profile picture; two thirds of this group had images containing human faces.

~29% had text in their profile which could be used to discover more about them, such as their sexuality, political views, or drug use.

Europe outsourced its digital backbone for decades.

Today, that choice has become a strategic liability.

New Nordic snapshots show how deep that dependency runs in 🇩🇰Denmark, 🇫🇮Finland, 🇮🇸Iceland, 🇳🇴Norway, and Sweden🇸🇪.

Let's talk about it! ⬇️ Image
Baseline: 74% of Europe’s publicly listed companies depend on US tech for email/security (the gateway to cloud, docs, identity, and security).

Nordics Stats

🇩🇰DK: 89% → 9 sectors at 100%; consumer staples distribution & retail 0%

🇫🇮 FI: 92% → 16 sectors at 100%; household & personal products 50%

🇮🇸IS: 97% → 16 sectors at 100%; household & personal products 50%

🇳🇴NO: 96% → 17 sectors at 100%; media & entertainment 75%

🇸🇪SE: 91% → 9 sectors at 100%; banks 27%

Read the full study: proton.me/business/europ…Image
When your company relies on US tech companies, you're not just outsourcing tech.

You're exposing your organization to strategic risks that are out of your control:

→ AI models trained on your company’s data
→ CLOUD Act–enabled surveillance
→ No say over data location
→ Critical sectors exposed to geopolitics

How much do you know about the most advanced censorship system in the world?

Framed as protection against "Western influence", China's Great Firewall controls the political + economic narrative for China's 700M+ users (a quarter of all internet users).

1/8
But it doesn't stop there...

A massive leak of 100,000+ documents has revealed that a Chinese company, Geedge Networks, is exporting GFW-style tech to authoritarian regimes worldwide.

Recipients include Kazakhstan, Ethiopia, Pakistan, Myanmar, & others.

2/8
Leaked job ads from them seek English speakers to work in Pakistan, Malaysia, Bahrain, Algeria, and India, all of which have track records of censorship.

One co-founder of Geedge Networks is Fang Binxing - known as the “Father of the Great Firewall.”

Imagine this: you open an email from your inbox and start reading.

In the background, text is fed to your AI extension, making it delete every email from your inbox.

This isn’t a dream; with AI agents and prompt injection attacks, it’s currently a possibility.

1/5 Image
Anthropic recently announced Claude for Chrome, a browser-based AI agent that can take actions on behalf of users.

The extension is currently only available as a preview to 1,000 subscribers on Anthropic's Max plan.

The limited release is due to security concerns.

2/5
The company has tested 123 cases representing 29 different scenarios.

They found a 23.6% success rate when browsers had no safety mitigations in place - mitigations managed to reduce this to 11.2%.

Make no mistake, there are real risks associated with using these tools.
