Black Hat have published my original CFP submission for "Listen to the Whispers: Web Timing Attacks that Actually Work". I put a lot of effort into this CFP to avoid being discarded as 'yet another timing talk' - you can find it in full here: i.blackhat.com/BH-US-24/cfp...

AUSA Hagan Scotten, former clerk for John Roberts, really put some mustard on his resignation letter.

if anyone happens to have a spare districtcon ticket, I'd love to buy it off you!

Your LLMs were backdoored years ago. remyhax.xyz/posts/plagai...

Usually I talk about cybersecurity, but my work feels kind of pointless while the US government is doing more damage to its own security than any of its adversaries, so I'm just getting wrecked and playing video games instead.

OpenAI shocked and appalled that an AI company would steal intellectual property www.404media.co/openai-furio...

weak.Pointer (Go 1.24+), runtime.AddCleanup (Go 1.24+), and sync.Map combine wonderfully into a 20-lines weak map. #golang It associates values to keys, with automatic garbage collection once the key becomes unreachable. Using it to tie precomputed FIPS keys to PrivateKey values we can't modify.

I'll be speaking at @districtcon.bsky.social ! We're gonna build custom Bluetooth hardware for $100 (no soldering required), learn well-informed shortcuts for remote identification, oblique strategies for exploitation, and pop some shells. Wanna learn why DoS is dangerous again? Come join!

Will start a running thread of the first day official proclamations and EOs; just links to the actual texts. If you want to tune it out feel free to mute the thread >

On January 19, 2025, ByteDance shut down access to TikTok and other owned/operated apps for US users, causing an 85% traffic plunge and a rapid shift to alternatives like RedNote. Here's what we observed: blog.cloudflare.com/tiktok-ban-t...

Here's a thing I made last year. It's a 16 step sequencer that throws Windows error sounds

The Meta AI lawsuit where they pirated massive amounts of academic papers using LibGen etc… is hilarious because those PDF’s are massively watermarked for 10 years now with embedded encodings and zero-width spaces. Congrats on breaking the law and invisibly poisoning your model

How do you fix a broken Bluetooth connection? You re-pair it.

mitmproxy 11.1 is out! πŸ₯³ We now support *Local Capture Mode* on Windows, macOS, and - new - Linux! This allows users to intercept local applications even if they don't have proxy settings. More details are at mitmproxy.org/posts/local-.... Super proud of this team effort. πŸ˜ƒ

Just starting to scan #IPv6 at application layer and already found a compromised device running a #MeshCentral #C2 #Panel

I got a Numworks calculator and I don't like that you have to log into their website to modify the scripts on the device so I created a python script to do that. I have only tested this with the N0120 running 23.2.5 firmware. STM32 under the hood, uses DFU for transfer. github.com/noctonic/nmwks

We broke something: in a recent pentest on a hardened target, we were able to achieve unauthenticated Remote Code Execution (RCE) via Server-Side Template Injection (SSTI) in a Spring Boot application We wrote it down for you to try at home: modzero.com/en/blog/spri...

check out this tool for easy Linux kernel building and debugging - easylkb made by me and @vacci.ne :) writeup: tmpout.sh/3/20.html repo: github.com/deepseagirl/...

New blog post. This time about being as accurate as possible to loading and injecting an executable image without touching disk. tl;dr use transactions and NtCreateSection/NtMapViewOfSection. amethyst.systems/blog/posts/m... Enjoy! #infosec #malware

According to Giraffe Security, AWS staff have somehow managed to re-introduce the same RCE vulnerability into its platform three times over the past four years giraffesecurity.dev/posts/amazon...

Eating ice cream but all I have are these stupid chopsticks this is bullshit

Wow @propublica.org is really killing it these days. By far some of the best reporting happening today.

It is both ethical and moral to reverse engineer everything you own, and you should.

sometimes, late at night, when it's dark and my wife is asleep, I like to indulge my deepest desires and google the twimst cat

I was having a hard time emulating an Atheros based router due to different MMIO regions. Well, after trying a bunch of different ideas, I'm currently able to use the actual device to record MMIO transactions via my custom virtual qemu board. MITM on MMIO works beautifully πŸ–€

I *really* wish Wireshark had tabs, I've got like 5 Wireshark windows open and it's a mess :v

It’s a long shot, but I’m looking for a ticket to ShmooCon. Please reach out if you or someone you know has one available, I’d be delighted to buy it for cost
