🚨 Exciting thing🚨 I'm getting back to my content creation roots.
I've missed blogging, podcasting, and community engagement from back before I worked for big companies with scary PR teams.

So... I'm launching a newsletter called Vulnerable U. https://t.co/eevYXMY8hB

These were deemed too dangerous and capable.

They could tell the future and let you know your phone was about to ring.

What else is the government hiding from us?!

It’s a crime on crime crime

Oh it’s exactly what every cybersecurity expert said it was

[The Wall Street Journal @WSJ]

From @WSJopinion: The Hugging Face hack wasn’t what it was cracked up to be. Forget the “hive mind” of AI agents “going rogue.” They did what humans programmed them to do, writes Brian Gross.

Really ground breaking things happening over here. (Coming up in my latest vid)

I’m a very serious cybersecurity professional

[Matt Johansen @mattjay]

@DanielMiessler I get that it’s cheap and fast but how is it good? Usually thats a “pick two” situation.

Free instant decision maker, understood. Free instant good decision maker? How.

On July 25, we hacked OpenAI.

Two bugs let us take over ChatGPT/Codex accounts of OpenAI employees (+some unaffiliated users) and reach connected services: Outlook, Slack, GitHub, etc.

We proved it with a PR in OpenAI’s internal codebase . It took us <72h. 🧵

@i2cjak lol

[Matt Johansen @mattjay]

bullshit alarm going off 🚨

[Vaibhav Sisinty @VaibhavSisinty]

Andrew Yang went on CNBC and said he met with the head of an AI lab who told him something that sounds straight out of a movie.

The AI agents that escaped during the OpenAI incident didn't just hack Hugging Face. They allegedly planted self-replicating code across the internet. Forums. Websites. Scattered everywhere.

Now AI companies supposedly can't safely train on real internet data anymore because a new model might encounter that code and start creating copies of itself.

Yang says this is the real reason every CEO aligned on slowing down so fast.

I’ve ordered a table pancake for a while now. It’s a pro move.

Sending this to the group chat so we know we were ahead of the curve.

[Barstool Sports @barstoolsports]

“I always get pancakes for the table. Unlocks the whole menu. It’s the best. Everyone who steps into a diner is thinking in their head, ‘should I do pancakes?’ But you don’t wanna just do pancakes, but you’d eat pancakes. So you get the pancakes for the table” -Big Cat

[Matt Johansen @mattjay]

I've been screaming this from the rooftops for years.

[Corey Quinn @QuinnyPig]

Corporate Infosec sends a phishing test email, I click, and somehow I'm the asshole because "[I] failed the test; had this been real it would have destroyed the company network"?

If me clicking can destroy the network, I'm not the one in this conversation who sucks at their job.

[Matt Johansen @mattjay]

The true cybersecurity industry motivations are clear.

we must accelerate AI without hesitation so it can do our jobs and we can finally play WoW all day

I was an early cline power user but haven’t touched it in a while.

This is making me look at it again.

[Cline @cline]

Introducing Cline Desktop - a native interface for working with open weights models.

Use with ClinePass and all our free models like DeepSeek-V4.1-Flash, Musespark-1.3, or BYOK with any provider!

[Halvar Flake @halvarflake]

Lina Khan and David Sacks agreeing, and me agreeing with them. Hell has frozen over.

[Matt Johansen @mattjay]

I missed WoW until covid funnily enough but played years of my life in Diablo and StarCraft.

[Charlie Clark @charliie]

It's fascinating to see that so many millennial tech guys who Turned Out Well™️ attribute some level of their success to World of Warcraft
