@wasabiwifey I should’ve said we’re good at lowering costs by outsourcing to China 🇨🇳🤣

New exploit: “xor dword [0xf80c2094], 1<<22”

Unlocks CPU microcode, the platform security processor, system management mode, and every internal processor register, all at once, on 100 million AMD CPUs. As far as I can tell can’t be fixed.

@the_cia_hacker I think your point about wanting to get caught and get the attention one never got from loved ones is really interesting. It’s an angle I’ve never considered before.

[Matthew Carr @int0x33]

@the_cia_hacker Agreed. I talk about this at length in my upcoming book.

A lot of people got arrested in the golden years of Anonymous. Many didn’t. The ones who didn’t understand that silence was key to survival.

Authorities track ego and money. Without either, you’re much harder to find.

The golden years of hacking are still ahead of us.

My timeline in August…

[Matthew Carr @int0x33]

Grace. Extend it to your family, your friends, and your loved ones, but most importantly, extend it to yourself.

[Matthew Carr @int0x33]

The thing most people forget about networking is the follow-up.

It’s hard enough to get out there and meet people, I know. But that’s only half the battle.

You’ve got to follow up.

Humans need interaction.
Interaction creates attention.
And money follows attention.

Writing a book has been much harder than I ever thought, and also far more rewarding than I ever dreamed.

[Matthew Carr @int0x33]

@alexanderrX_ Yes! This is exactly the kind of thing we need to be doing.

The best time to build generational wealth was yesterday. The second-best time is today.

Lock in.

China 🇨🇳 is moving fast. The energy here is incredible.

Honoured to become a Freeman of the City of London - a distinction that carries centuries of history, tradition, and civic service. Grateful for the recognition and looking forward to contributing in the years ahead.

[Matthew Carr @int0x33]

Honestly, I’m so excited to land in China 🇨🇳 later today

[Pat Walls @thepatwalls]

The cars in China 🇨🇳 are incredible. Like I’m sitting in an actual recliner on my ride to the airport. It has cooling seats and it’s giving me a massage rn. $25 USD for an hour long ride.
