Researchers pointed a satellite dish at the sky for 3 years and monitored what unencrypted data it picked up. The results were shocking: They obtained thousands of T-Mobile users' phone calls and texts, military and law enforcement secrets, much more: www.wired.com/story/satell... 🧵👇

Satellites Are Leaking the World’s Secrets: Calls, Texts, Military and Corporate Data

With just $800 in basic equipment, researchers found a stunning variety of data—including thousands of T-Mobile users’ calls and texts and even US military communications—sent by satellites unencrypte...

No a few years ago they switched to their own root store. They do pull in certificates that the user adds but not the platform root store.

Another Sleeping Giant: Microsoft’s Root Program and the 1.1.1.1 Certificate Slip | UNMITIGATED RISK

The bigger issue? Microsoft’s root program still trusts this CA, leaving Edge and Windows users exposed in ways Chrome, Firefox, and Safari users aren’t.

The pattern is familiar: long-lived trust, weak oversight, systemic risk. It’s time for Microsoft to step up and fund proper root governance.

This morning, a serious WebPKI incident surfaced: a tiny CA misissued certificates for 1.1.1.1 - Cloudflare’s DNS service.

With BGP hijacks happening regularly, those certs could enable full man-in-the-middle attacks.

Looks like something is up in Whoville. It seems an obscure CA trusted by Microsoft has issued a certificate for 1.1.1.1.

Big milestone for email security. CA/Browser Forum just published S/MIME BR v1.0.11. Now with NIST-approved post-quantum algorithms (ML-DSA & ML-KEM). Quantum-resistant S/MIME is here. 👇

These flaws, combined with poor security practices from RMM vendors like ConnectWise & Atera, create a malware pipeline that offloads security costs directly onto customers.

How Microsoft Code Signing Became Part of a Trust Subversion Toolchain | UNMITIGATED RISK

Building on the great research by Cem Paya and Matthew Ludwigs at River Financial, my new post details how attackers are exploiting fundamental assumptions in Microsoft's code signing.

With Authenticode & CA/B Forum–compliant code signing, intent ≠ immunity.

The Baseline Requirements define revocation conditions based on use in the wild, not the developer’s intent.

Ship signed code? Design it to resist abuse — attackers can weaponize your trust, and your cert can be pulled.

One of the best parts of Black Hat is the hallway track.
This week, I got to watch some great talks with friends, and one reminded me of a common pattern, the innovation–security debt cycle:

1️⃣ Rush to ship
2️⃣ Debt builds
3️⃣ Incident forces change
4️⃣ Security becomes a differentiator

History Doesn’t Repeat, But It Rhymes: The AI Panic Edition | UNMITIGATED RISK

In the 1960s: "Don't have kids, the world will starve." Today: "Don't learn to code, AI will do it all."

Both predictions ignore the same truth, when there's money to be made, markets adapt faster than doomsday forecasters expect.

We build systems to make things easier. But too often, what we call “automation” ends up feeling like digital red tape, frustrating, rigid, and impossible to reason with.

My AI Skill Liquidity series shows the same pattern, value shifts from execution to orchestration. But today legal AI focuses on documents, not reasoning.

We're accidentally breaking apprenticeship while missing the intellectual core of legal practice.

Lawyers Think Like Security Engineers. AI Treats Them Like Secretaries | UNMITIGATED RISK

As a recovering security engineer, I recognize threat modeling anywhere.

Lawyers do it constantly - they're security engineers for text.

So why does legal AI treat them like secretaries?
