I'm impressed by how light weight the Apple on-device Foundation LLM is for Apple Intelligence, so I vibe'd a small macOS tool (26.0+) to interact with them. It supports GUI and CLI and tool calling. Even big responses fail to move the CPU/GPU by a single percentage. Link below.

How Hacked Card Shufflers Allegedly Enabled a Mob-Fueled Poker Scam That Rocked the NBA WIRED recently demonstrated how to cheat at poker by hacking the Deckmate 2 card shufflers used in casinos. The mob was allegedly using the same trick to fleece victims for millions.

Two weeks ago, we at WIRED published a video showing how a hacked casino card shuffling machine can be used for undetectable cheating in poker. Now it turns out the mob and a couple of NBA stars were already (allegedly) using exactly this trick to make millions. www.wired.com/story/how-ha...

So, I had posted this as a reply, but figure it might be better as a thread.

It turns out the Trump administration uses an app called TeleMessage to access Signal. Its source code leaked online ( @micahflee.com!)

WHAT DID WE LEARN FROM THE TELEMESSAGE SOURCE CODE (for absolute beginners)?

If there's one thing I've learned about covering cybersecurity over the past decade or so, is that the cybersecurity community (the fixers and breakers) and the cybersecurity industry (profits above all else) are two very, very different things.

Today Microsoft announced Windows 11 will require a Microsoft account to create a local profile on the computer. They will be removing the bypass option available in the installation command prompt.

There will still be workarounds, but they're making it harder

The ESP32 "backdoor" that wasn't | Dark Mentor LLC 4 day class covering the full Bluetooth Low Energy (BLE) protocol stack from the bottom (PHY) up to the top (GATT). The core of the class is built around playing with a game application on an Android phone, talking via Bluetooth to an IoT-type piece of hardware, and analyzing the communication between them. The 4th day is focused on assessing a cutomized Ultra-Vulnerable Peripheral firmware, running on Zephyr RTOS, which has had vulnerabilities introduced into it which are representative of vulnerabilities found in the past across many other platforms.

Iโ€™ve posted a detailed explanation of why the claimed ESP32 Bluetooth chip โ€œbackdoorโ€ is not a backdoor. Itโ€™s just a poor security practice, which is found in other Bluetooth chips by vendors like Broadcom, Cypress, and Texas Instruments too. https://darkmentor.com/blog/esp32_non-backdoor/

One of the most insufferable parts of the rise of LLMs is people who see a post or a question or whatever, paste it into an LLM, and the respond with โ€œI asked an LLMโ€ and paste the output.
