Exploit published ^

microsoft word, the predecessor to microsoft dword,

Quite proud of myself for successfully building a Windows 16-bit application that runs on Windows 3.1 - all dialog-based, and it makes network connections, too! Compiled with Visual C++ 1.52 on XP, it works on this old system. Consumes 14kb disk space and does everything in even less RAM :)

https://techcommunity.microsoft.com/blog/windows-itpro-blog/hotpatch-for-windows-client-now-available/4399808 Finally! I personally worked on Hotpatch, together with my team 3 years ago... and now is finally approaching client versions of Windows... Yuuuyuuu!

Kernel-Hack-Drill: Environment For Developing Linux Kernel Exploits

Alexander Popov @a13xp0p0v published the slides from his talk at Zer0Con 2025. In this talk, he presented the kernel-hack-drill open-source project and showed how it helped him to exploit CVE-2024-50264 in the Linux kernel.

Love the absolute units! (And I suck at photography)

Did a post on the personal blog (i.e., “the views expressed by me do not…blah blah”) — “Trump’s Retaliation Against Chris Krebs — and the Cybersecurity Industry’s Deafening Silence”.

Unlike most years, everyone attending RSA next week has a tangible, meaningful opportunity to make a difference.

Be better than the complicit cowards (humans & vendors) in our industry, speak up, & hold folks accountable.

Otherwise, “Many Voices. One Community” is just BS RSA marketing.

"Providers are pushed to spend less time caring for each patient as health systems move to reduce costs and increase revenue under the technological principle of maximal efficiency and output. But medicine was never intended to be another industrial complex."

This essay is beautiful and powerful.

Today my #rust compiler told me "expected future, found a different future".

And I'm like: me too buddy, me too

[RSS] New writeup: a vulnerability in PHP's extract() function allows attackers to trigger a double-free, which in turn allows arbitrary code execution (native code)

Can't find official identifiers for this, the GitHub advisory link is broken...

Never forget.

Maybe you should build your own website https://neocities.org

I got #X11 running on the #PinephonePro under #FreeBSD ! Shown here running my favourite #icewm window manager. Super exciting! Now to get the touch screen working 😬

I never liked nu metal and I feel retrospectively justified by the fact that both Fred Durst and Kid Rock seem to be almost uniquely brain damaged even today.
