Reverse Engineering or Necromancy? 🧟‍♂️⚖️

What do you do when the company goes dark, the app vanishes from the App Store, and your "smart" scale becomes a 100€ paperweight?

You reverse it.

I’m starting a new series on ByteArchitect about bringing the QardioBase2 back to life. No ChatGPT-farts here—just raw bluetoothd logs, GATT discovery, and the sad sight of a backend that keeps saying "cancelled."

In this first part:
- Sniffing BLE traffic on iOS (without a jailbreak)
- Mapping proprietary GATT services & characteristics
- Realizing the servers are officially dead (RIP Qardio)

If you despise planned obsolescence as much as I do, join me in this "zombie" recovery:

Apparently Electric Eye made it to riskybiz. Not bad for day one.

Stop chasing blacklists. It's a losing game. I built a Rust engine
to spot AitM proxies where they bleed: in the DOM. Meet Electric Eye.

New post: Hardening macOS pt.5 — Communications

Email clients, providers, PGP, and chat. For a Cypherpunk, talking about communications is like talking politics at the pub. I tried to be factual. Mostly succeeded.

Also: a special note for my Italian readers on PEC. With appropriate levels of contempt.

No Hardening macOS this week. Got distracted.

Starkiller is a new phishing kit that proxies REAL login pages in real-time. It steals credentials, MFA tokens and session cookies — and MFA won't save you.

I wrote a full technical analysis: how AitM works, why traditional defences fail, and what to actually do about it.

Also released ja3-probe, a Rust PoC for TLS fingerprinting of phishing proxies.
