[Josh Terrill @joshterrill]

My Windows reverse engineering and exploit research workflow has been:
1. Pick a binary to research like tcpip.sys
2. Use https://t.co/fOxBB6tEsN to automate seeing existing binary versions, download, and generate diffs from them
3. Load the resulting .binexport's and .bindiff into an LLM and ask it to analyze
4. Look up the build number of previous Windows version that old binary existed in from https://t.co/U788ndiJbj such as 26100.8328 and create a VM from it
5. Write code and test, working backwards from LLM analysis

There it is! Orange Tsai (@orange_8361) of DEVCORE Research Team was able to exploit Microsoft Exchange! If confirmed, they win a whooping $200,000 and 20 Master of Pwn points. Off to the disclosure room to explain how they did it and seal the deal. #Pwn2Own #P2OBerlin

If you are in the UK we are looking for a principal security researcher to join the team. If you have a threat hunting or incident response background, especially if you deeply understand Entra and other Azure technologies, this may be the role for you

I hacked Claude Code! It turns out "agentic" is just a fancy new way to get a shell. I achieved full RCE and hijacked organization API keys. CVE-2025-59536 | CVE-2026-21852

Want to consume Microsoft-Windows-Threat-Intelligence but Antimalware-PPL getting you down? No problem! I will post a blog & POC soon - but this allows you to consume Threat-Intelligence without PPL _and_ w/o any kernel patching/driver loading gymnastics! Only need admin!

[NiNi @terrynini38514]

Just published an IDA plugin: HappyIDA

Built with @h3xr4bb1t and @scwuaptx , and I’ve been using it in my daily reversing work for 1~2 years.

There’s still a lot to do, but it felt like the right time to make it public, so we’re more likely to fix things (and hopefully some kind stranger will help us)

It’s fancy, but not that fancy. Honestly, IDA Pro would be better if they adopted some of these ideas.

There is no complex algorithms, no timeless debugger, no symbolic execution,
but just a bunch of tiny features that have already helped me speed up reversing a lot.

(The screenshot shows the origin of the project and the first feature I implemented: parameter labeling. @h3xr4bb1t later made it much more powerful. The SEH highlighter was made by @scwuaptx, and the SEH rebuilder was made by @h3xr4bb1t)

weird. the same EXE content with "Update" in filename, windows will force this EXE only UAC elevated to run or not.

Is that a windows necessary feature? 😂

VXCON 店長 17-and-7-month year old Baileys is now living at Rainbow 🌈 Bridge on last Sunday night after VXCON completion, with love, hugs, and winds.

Sadness and sorrow are still pumping but life must go on

VXCON community always supports animals charity, continue to make them happy with love.

After VXCON, I want to take further action to gather fund / donations to support animals charity including 阿棍屋，taking care of elderly dogs and cats. They need more care and love. Resources are needed.

If you provide donations (like minimum 500 HKD, share and give us receipts), we probably set up a member-only discord channel to share the hardcore and latest engineering, research and hacking techniques there.

I hope I can get at least 10 people to start the group. If yes, please leave comment or PM me.

Thank you very much to everyone, and Baileys is our life-long VX captain 店長, and I hope we can make our animals better.

A research by RETooling crew (@DrCh40s && @t0nvi). Nicely done, chaps!
