yippie-kee-yay! just added teensy4.0 support to #klutshnik #zephyr - the 4.0 is smaller and cheaper than the 4.1 but comes with the same powerful cortex-m7 mcu. with this change klutshnik now runs on 4 different embedded systems: xiao_esp32s3, rpi pico2 (w) and the teensy4.1 and teensy4.0. \o/

also rewrote the provisioning interface which is now a proper shell on usb cdc-acm.

Hi, I'm your favorite security vendor, welcome to...

RE: https://infosec.exchange/@tiraniddo/115295709143228986

Well, Windows Administration Protection still hasn't been released even though technically 25H2 has. So none of those 6 bypasses have been fixed, but then again there's no code to bypass, so.... At least some of them are fun UAC bypasses :)

⏲️ One week left for r2con2025! Are you ready? #r2con

I'm really curious how libtiff is embedded in Windows so that CVE-2016-9535 could apparently lead to RCE in 2025

Let's make something amazing!

I think it was @david_chisnall who pointed out earlier that coding LLM's will become much less useful when we stop doing (expensive) training to keep up with breaking changes in API's.

Well, I just spent two hours trying to fix some code that was buggy because the API changed less than a year ago and came to the decision of reading the F manual and write that 200 LoC myself.

(to be fair, I think this would work if the LLM had access to a complier and runtime)

[RSS] Oops! It's a kernel stack use-after-free: Exploiting NVIDIA's GPU Linux drivers

http://blog.quarkslab.com/nvidia_gpu_kernel_vmalloc_exploit.html

Hackers can steal 2FA codes and private messages from Android phones. The "Pixnapping" attack is a really clever piece of research. It shows that the theoretical wall between apps on your phone isn't as solid as we'd like to believe. By exploiting a GPU side channel, a malicious app with zero permissions can effectively screenshot other apps, one pixel at a time. It's a reminder that security is a stack, and a vulnerability at the hardware level can undermine everything built on top of it.

TL;DR
👾 A new attack called "Pixnapping" can read visual data from other apps on Android devices.
🔑 It exploits a GPU side-channel leak to steal sensitive info like 2FA codes and messages, pixel by pixel.
⚠️ The scary part: the malicious app required for the attack needs zero special permissions to be granted.
🧠 While complex to pull off, this is a serious proof of concept that challenges the core idea of OS app sandboxing.
