I take scam fighting personally, been doing it for over 25 years.

It pisses me off.

GSE is bringing people together to offer simple tools to keep us all safe online.

I’m putting my money where my mouth is.

Cyberattacks are increasing in frequency, sophistication, and harm — disproportionately affecting civil society organizations, journalists, and human rights defenders.
The Common Good Cyber Fund strengthens the public-interest cybersecurity ecosystem and supports nonprofits protecting civil society.

Open call launches June 2026.

Very kind article via Jennifer Swann, particularly regarding insights from Jessa Lingel. (I need some way to remind people that the revenue stuff citation is totally sus.)

"It’s a utopian vision of a much earlier, far more earnest internet."

"Newmark says he still gets angry about the idea of somebody trying to rip off his customers. “I take it personally, and I think everyone involved in any kind of platform should feel the same way,” he says. “It should piss them off.”"

Hackers don’t just forecast cyber risk, they demonstrate it.

The DEF CON 33 Hackers’ Almanack report is blunt, technical, and long overdue. The Almanack translates real exploits into a policy roadmap leaders can’t afford to ignore. #CyberCivilDefense #Take9
