Over the past two days, we released new versions of StartOS, StartTunnel and 100+ services to patch the security issues from eMudhra, PHP, and Node.js and others.
We recommend updating ASAP.

Let's try running a Bitcoin Core-powered signer in your browser. A real Linux system, right inside a webpage.

Imagine someone gives you a lock and tells you it's the safest lock in the world.
You ask how they designed it.
They say, "We picked some special numbers. Trust us."
Now imagine that someone is the NSA.
That's essentially what happened with some of the elliptic curves standardized by NIST. These mathematical curves are used to secure digital communications, and some contained mysterious numbers whose origins nobody could explain.
For decades, cryptographers wondered whether those numbers had been deliberately chosen to hide a secret weakness.
Then Claude investigated and found something remarkable: the mysterious seeds apparently came from an ordinary 1990s random-number generator initialized using a computer's clock.
No evidence of a secret mathematical trap. Just surprisingly mundane mathematics.
Now here's where Bitcoin gets interesting.
Out of paranoia, Satoshi chose a different, not widely used curve, secp256k1, with an extraordinarily simple equation:
y² = x³ + 7
No mysterious seed needed to explain its shape, just a 7.
We don't know whether that motivated Satoshi's choice, but it illustrates something fundamental about Bitcoin.
Security shouldn't depend on trusting the people who designed the system.
Even if the NSA never intended anything malicious, asking where those numbers came from was absolutely the right question.
Because the goal of cryptography isn't to prove that everyone is trustworthy.
It's to build systems where they don't have to be.
Don't trust. Verify.

Every so often a tweet comes from bitcoin twitter that makes me feel like a complete moron. This is definitely one of those.

Si quieres privacidad en Bitcoin lo primero es tener un nodo propio en lugar de filtrar saldos a terceros sin saber que harán con esos datos. Mira y sorpréndete.

₿ No es solo un nodo de Bitcoin. Es nuestro propio servidor soberano de Bitcoin.
🔧 Un mini PC, RAM y SSD.
Hardware bajo nuestro control, verificando cada bloque y transacción sin depender de terceros.
La soberanía empieza en casa.

I think the main reason we do not see implants in the Nano S/S+ is that the implants originally required changing the battery with something smaller.
Now that they worked out living behind the screen, we may see implants targeting those devices too.

The French government is and will be held responsible for the kidnappings and murders of these individuals. While it is gangs that carry out the abductions and killings, the French state provides them with exact addresses.

Situation Update: Ledger can confirm that one of the impacted users’ devices contained an unauthorized hardware implant. Ledger is reaching out to impacted users as part of the ongoing investigation. If you have information regarding the investigation, please reach out to Ledger’s bounty program: [email protected]. As a measure of precaution CryptoBilis confirmed it has ceased sales of all hardware wallet inventory until the investigation is concluded. Ledger is in active communication with CryptoBilis on next steps.
Ledger is working with the appropriate authorities to bring the bad actors to justice, and thanks @SEAL_911 for their collaborative support on the investigation. We have no indication that Ledger’s security infrastructure, systems or services have been compromised. As a reminder, Ledger recommends users who purchased a Ledger device from this reseller to not initiate set up if they have not yet done so. If you have set up your Ledger device, consider moving assets to a new Ledger signer (with a new seed).
Security is a constantly evolving landscape; Ledger is continuously adding security mitigations and is working on further, enhanced anti-tampering solutions.
Scammers often try to take advantage of incidents like this. Rely only on official Ledger channels for updates, and remember: Ledger will never ask for your 24-word recovery phrase.
