This past week I interviewed Keith McHenry, co-founder of #FoodNotBombs! - begun in 1980 in Cambridge, Massachusetts, offering free #vegan food to anyone, as a protest against war and poverty. The genius idea caught hold with autonomous chapters in 60 countries.

A bunch of great people are offering help and vendors + hosts are (mostly) responsive to abuse reports for these #botnets. I'm still being targeted in the most personal way #Aisuru operators can. Most of that I'll talk about soon. Thanks esp. to @briankrebs.infosec.exchange.ap.brid.gy

🙌 My request for the 14emeliaterracewestroxburyma02132 domain associated with the Aisuru #botnet to be terminated has been granted.

This was the most visited domain on the Internet yesterday, far above #Google, #Facebook, #Microsoft, #Apple, and #Amazon.

The additional domain overload [dot] su now too. h/t @briankrebs.infosec.exchange.ap.brid.gy - this is the Aisuru botnet taking different forms. krebsonsecurity.com/2025/10/aisu...

🚨 There's an enormous amount of traffic at a .su domain (old Soviet Union TLD), per #Cloudflare Radar. It's outranking every other big domain out there (#Google, #Microsoft, #Facebook, etc.) I assume this is related to a botnet controller and the #Azure outage...

I was quoted in another great piece on #genAI at @zdnet.bsky.social:
"When generative AI systems ingest thousands of #FOSS projects and regurgitate fragments without any provenance, the cycle of reciprocity collapses." www.zdnet.com/article/why-...
Why open source may not survive the rise of generative AI
Generative AI may be eroding the foundation of open source software. Provenance, licensing, and reciprocity are breaking down.
