Claude Fable - Microsoft zero days - this week in ai & cybersecurity x.com/i/broadcasts/1…
a new github account named MSNightmare just posted a Windows Defender exploit with PoC that works on Windows 11 and 10. They say Windows Server is vulnerable too but the PoC needs to be tweaked. Guessing the github wont be up long if this is NightmareEclipse who was banned.
Vulnerability avalanche time!
Me and my college roommates organized a charity event where we wouldn’t eat for 24 hours and raise money for the World Health Organization. We’d lock ourselves at home and to kill the day we’d have multiple N64s trying to beat Ocarina of Time in one sitting. This is awesome.
The Legend of Zelda: Ocarina of Time will be reborn on Nintendo Switch 2 in 2026. #NintendoDirect
I’ve toured a fair bit of battleships as a history nerd but never thought I’d swim through a sunken one. Very cool experience.

You’ll never guess what this tweet is replying to.
@JohnHultquist @SLEUTHCON Really bummed the dates didn’t work for me this year. One of the best cons going. Way to go John.
Saw a shark and the biggest turtle I’ve ever seen on this morning’s dive. So that’s pretty legendary. Pics incoming.

@uwu_underground PREACH. TikTok is full of em.
Now I want @HunterBiden to come on my YouTube and talk about how to not get your laptop hacked. Let’s drive some personal Opsec awareness.
MSRC couldn’t possibly do anything worse this week… oh. Oh ok.
