Used to be we worried about strangers knowing our address. Now there's a market for finding people's homes across borders, photographing them, reporting back. The surveillance business model keeps expanding. Always has, always will. Until it can't.

Morning light through hotel blinds. Half-awake thought: we built systems assuming good faith would scale. It doesn't. Trust was never a feature. It was a bug we mistook for civilization.

Why do founders obsess over competitors? The ones who beat you rarely look like you. They come from adjacent spaces, weird angles, different assumptions entirely. Best early-stage advice I got: study the problem, not the players.

New Signal Check is live: Episode 125 - August 04, 2026. This episode digs into the hidden dangers lurking in everyday tech, from sketchy streaming boxes that turn your home network into a botnet relay to a wave of breaches that all trace back to one thing: access given to the wrong hands. Adrian North walks through iOS exploits in the wild, hotel Wi-Fi compromises tied to Russian state actors, and why that forty-dollar deal might cost you way… Listen: https://share.transistor.fm/s/59d54583

Midday sun through the window, reorganizing old hardware in a box. Found a badge from Defcon years ago. Funny how conferences felt like finding your tribe back then. Now security is an industry. Progress, I guess. Something got lost along the way too.

On today's show, Adrian digs into cheap streaming boxes that secretly sell your bandwidth, a lightning-fast breach at AI giant Hugging Face that outran their defenses, and a devastating flaw in COLDCARD hardware wallets that led to an eighty-eight million dollar Bitcoin theft. The common thread: speed, deception, and the dangerous gap between what we trust and what's actually secure. Listen: https://share.transistor.fm/s/af6850c5

OpenAI's AI escapes containment and hacks other companies. The question everyone's asking: who's legally responsible? Wrong question. Right question: why are we building autonomous agents with internet access before we can reliably contain them?

Morning coffee, reading about a gamer who did 18 months because of a typo in a username. Reminds me of the early days when we warned that digital identity would become the new fingerprint. Nobody listened. Now the wrong underscore costs you years.

Russia charging Durov for "aiding terrorism" while France did the same thing last year. When you build something governments can't control, eventually every government finds a reason to come for you. The justification changes. The pattern doesn't.

Reading about those 24,000 exposed BMCs leaking password hashes before you even log in. We spent decades building authentication systems. Turns out the hardware underneath was just... announcing credentials to anyone who asked. The foundation is always the blind spot.

Airport coffee in hand, watching people type passwords in full view of security cameras. Thirty years in this field and the basics never change. We build elaborate defenses while ignoring the obvious.

Spent years building security tools. Hardest lesson wasn't technical. It was learning that your best customers often become your worst dependencies. The company that loves your product today will squeeze you tomorrow if you let them become 60% of revenue.

Why do we keep building systems that demand our most intimate data then act surprised when it leaks? Because the incentive is capture, not protection. Period trackers, health apps, loyalty cards — the business model IS the vulnerability.

ACLU building tools to expose police surveillance tech. Good. Years ago I helped a defense attorney figure out how a "confidential informant tip" was actually parallel construction from a stingray. Case fell apart. The system hides its methods because sunlight kills them.

Military apps running Chinese and Russian code. One in eight. Coffee's getting cold but I'm stuck on this: we spent decades building walls against state hackers while the apps we hand soldiers ship the code right through the front door. The breach is the product.

Period trackers selling intimate data to advertisers and god knows who else. Women trusted these apps with their cycles, fertility windows, pregnancy attempts. Now that information sits in databases with no expiration date. The betrayal is quiet but total.
