You want to load your shellcode in .NET without calling VirtualProtect? Use RuntimeHelpers.PrepareMethod to create a predictable RWX memory region for you. This method also doesn't require a delegate function pointer, since you override a .NET method. github.com/Mr-Un1k0d3r/Do…
Teaming with @gh0stbyt3, we built DiffRays for headless IDA (@HexRaysSA) decompilation. It stores decompiled code in a SQLite DB and provides a Web UI for diffing between the stored functions. Built for vuln research. github.com/pwnfuzz/diffra… #pwnfuzz
Woohooo! Working on final post for Month of AI Bugs! Can't believe I followed through with this 😀 Hope it serves as useful reference + inspires many to get into AI security testing! We need more people asking tough questions & holding vendors accountable Let's do this! 🚀
Do you want to trigger shellcode only when: - Certain DNS resolution happens? - Certain servers are reached out to? - When you get a 112 byte long response? ...etc Meet InternetSetStatusCallback() for fine tuning execution (or if you are just bored): gist.github.com/whokilleddb/59…
Thanks to everyone who joined my DEFCON33 talk!🎉 For those of you who missed it and are interested in seeing how we can extract cleartext credentials and bypass MFA directly from the official Microsoft login page, I just uploaded the recording to YouTube: youtu.be/z6GJqrkL0S0
An infostealer that runs in the browser? Kinda. In our latest research, we explore how Chromium File System APIs can be abused to exfiltrate mapped network drives with a single drag-and-drop. Blog: blog.delivr.to/filejacking-ex…
Just completed my longest training session ever- 10,5 hours straight talking phishing talk 😍 Exhausted but equally pumped to have a brilliant class that sticked with me this long 🤯 Everything worked except Browser In The Middle part that swallows all RAM and CPU you give it 😅
Today, together with Jonathan Elkabas, we're releasing EntraGoat - A Deliberately Vulnerable Entra ID Environment. Your own hands-on Entra lab for identity attack simulation. Built for red teams, blue teams and identity nerds. Check it out here👉github.com/semperis/entra…

Two years ago, I left red teaming for a new challenge in endpoint security. I'm humbled by the incredible team we've built and so proud to share this research preview of our work. It’s an idea I believe in deeply, and I can’t wait for what’s ahead. 🖤

Now that there are tons of these and I can never find them when I need them, thanks @Oddvarmoe for showing me all the LOLS lolol.farm
A few weeks ago, I was responding to a cybersecurity incident - $500,000 have been stolen from a #blockchain developer. The infected operating system was freshly installed, and the victim was vigilant about cybersecurity. How could this happen? New supply chain attack? [1/6]
New? Initial Access maybe, yep we all heard of WSL and it's great integration with Windows you can build "WSL" file extensions. Maybe these files are 100MB+ but we can double click, and achieve command execution!!. Was tricky but working!! #redteam
It's here. The latest iteration of our Top 10 includes the most important developments in initial access tradecraft; from macOS targeting of ClickFix, to Zip Smuggling, to QRLJacking. 📚 Blog: blog.delivr.to/delivr-tos-top…
excited to be back in vegas for my second @defcon, and second talk on the creator stage! i’ll be diving into a mix of my favorite things: network fingerprinting, honeypots, and ai agents! tool drops in a few days--stay tuned 👾defcon.org/html/defcon-33… @wallofsheep
