Diagram titled “Transformer attention.” It shows three steps of the attention computation with code snippets beside each step. The first step is “Scale factor 1/√dₖ,” highlighting code that computes the reciprocal square root. The second step is “Dot product Q · K,” showing code performing a dot-product accumulation. The third step is “Scaling + max tracking,” highlighting code that multiplies by the scale factor, stores the value, and updates a running maximum. The phrase “Transformer attention” appears prominently in the center.

Just have the shell ask the user to check the host IP on first boot.

If they type ifconfig they are old enough, if they type ip addr they deserve to be restricted from their computer 😇

AirSnitch: Breaking Wi-Fi Client Isolation: Technique Index, Tool Usage & Defenses This morning I came across another interesting paper submitted at the NDSS Symposium 2026 like the BLERP paper already documented in this forum, but this time challenging the Wi-Fi client isolation th...

Think your guest Wi-Fi is isolated from your main network? Think again.
AirSnitch (NDSS'26) breaks client isolation on every router tested: from home APs to enterprise WPA2/3-Enterprise. Full MitM in seconds, sometimes leaking WPA2 traffic in plaintext: 🔗 community.penthertz.com/t/airsnitch-...

We found that Wi-Fi client isolation can often be bypassed. This allows an attacker who can connect to a network, either as a malicious insider or by connecting to a co-located open network, to attack others.

Reverse engineering Realtek RTL8761B* Bluetooth chips, to make better Bluetooth security tools & classes | Dark Mentor LLC We hold this truth to be self-evident&#58; SUFFERING BUILDS STRENGTH! In this talk I will walk you through the trials, tribulations, and triumph(!) of the worst debugging setup I've ever hacked together, which I used to reverse engineer the Realtek RTL8761B* family of Bluetooth chips.<p>This work was done because Bluetooth security tools are in an abominable state. We use "CSR4" (Cambridge Silicon Radio) dongles that don't support packets newer than Bluetooth 4.0 (released in 2010!), just to be able to spoof the Bluetooth Device Address (BDADDR) for MitM attacks.<p>Veronica Kovah & I have been creating Bluetooth security classes for <a href="https://ost2.fyi/">OpenSecurityTraining2</a>. And we wanted to use better hardware; ideally something that supports BT 5.4 (released in 2023). So I bought a bunch of cheap dongles off Amazon, and found that most of them used the same RTL8761B chip. So the goal was clear&#58; at a minimum, figure out a way to spoof the BDADDR on these dongles. But I also a set out a nice-to-have stretch goal - to figure out how to use these dongles to send custom LMP packets (which are architecturally not meant to be under full user control.) That way, could replace a bulky and expensive $55 dev board (that is only used for BT Classic), with a cheap and small $14 USB dongle (which has a better antenna to boot!) This would make Blue2thprinting (released at Hardwear.io 2023), and thus Bluetooth reconnaissance & vulnerability assessment, cheaper & better.<p>Bloodied (but not broken) by the ordeal, I achieved my goals and stretch goals. And given that there are no public descriptions of how Realtek Bluetooth chips work, I look forward to sharing hitherto-unknown information about how to navigate and understand these mostly-16-bit-MIPS-code systems. And I'll discuss how their ROM-"patch"ing firmware update mechanism works, how you can patch it to change its code too, and the security implications thereof.
