When Assad’s regime collapsed, @reuters journalists were among the first on the ground, reporting from a country entering a new and uncertain chapter.

AI is supercharging cyberattacks on orgs least equipped to defend themselves. @CLTCBerkeley Ann Cleaveland proposes "Project Kaleidoscope,” a community cyber defense model built on human trust, not just tech: https://t.co/sRbJp3c7jg

We added scanning of Automatic Tank Gauge (ATG) systems to our Accessible ICS reporting with 1061 IPs seen on 2026-06-05 (on port 10001/tcp).

This is after weeding out vast majority which appear to be honeypots (including ports 8001/9001). Vast majority exposed are in the US.

Three Predictions:

1. Some form of AI, probably neurosymbolic in nature, will come that is far more economical and data- and energy-efficient than LLMs, and it will make an absolute fortune.

2. LLMs, on the other hand, will never be all that profitable (aside from the chip companies selling shovels in the gold rush).

3. Today’s gigantic bets are premature, and most won’t pay off.

Recent advancements in quantum computing means that the encryption currently securing Internet traffic will not remain sufficient much longer. Check out this new post by Let’s Encrypt Engineer Andrew Gabbitas about ISRG’s plans to secure a post-quantum-safe web.

There’s still “a lot of work” that needs to be done when it comes to fundamental #cybersecurity, says @IST_org's Michael Klein. “Oftentimes people are not even hacking in; they’re just logging in.” A first step? #PauseTake9

I enjoyed speaking with Jonathan Weber for his book “City on the Edge”, which comes out June 9. He looks at how and why the internet industry blew up in San Francisco beginning in the early 1990s, and explores how it changed the politics and culture of the city in subsequent decades. It’s a fun and enlightening read
