Trusted access for the next era of cyber defense OpenAI expands its Trusted Access for Cyber program, introducing GPT-5.4-Cyber to vetted defenders and strengthening safeguards as AI cybersecurity capabilities advance.

#OpenAI shots fired
“We don’t think it’s practical or appropriate to centrally decide who gets to defend themselves. Instead, we aim to enable as many legitimate defenders as possible, with access grounded in verification, trust signals, & accountability.”

he infosec community loves nothing more than a hype cycle. But they're not very useful for defenders who are trying to keep users safe, so we talked with @k8em0.bsky.social and Gary McGraw about the Claude Mythos hype v. reality.

Everyone's worried about the Vulnpocalypse, vulnmageddon, vulnerability storm brought on by #AI like #Mythos, but what if we treated this like a music festival? We all have tickets to Vulnapalooza. Here's your festival survival guide.

Why a powerful storm in the Western Pacific may be a concerning sign It is unusually early for a super typhoon in the western North Pacific.

Super Typhoon #sinlaku is not just threatening the Mariana Islands, the US territory home of my mom’s side of the family, but it’s disturbingly early in the season & powerful — a signal of a possible hard typhoon season to come.

Preparing your security program for AI-accelerated offense | Claude We share our initial set of recommendations to shore up your defenses based on our own findings and security practices.

Great advice from Anthropic on prep for accelerated AI vulnerability discovery, including what to do if you don’t have a dedicated security team, if you’re reporting bugs you found, or are an open source maintainer.

Many of you know that @lutasecurity.bsky.social is named for the nickname of Rota, the island my mom was born on and where I still have lots of family. Super Typhoon #sinlaku is heading straight for Rota. Praying for all in the Marianas to be safe. đŸ™đŸŒ

The technical debt repo man is coming for all orgs, especially those that don’t have robust patch creation & management — & it’s clear we can’t keep cranking out these bugs in the 1st place. Stay hydrated, ops teams, & tip your doordashers well as we brace for impact of the #AI vulnpocalypse

Yes but how long will releasing full new versions with multiple non security changes be enough noise to slow down AI analysis when AI can systematically diff entire version updates to find the security holes? We have a serious update problem ahead, & we don’t have a safe AI answer to speed it up yet

How A.I. Helped One Man (and His Brother) Build a $1.8 Billion Company

This guy built a telehealth provider of GLP-1 weight-loss drugs using AI tools like ChatGPT, Claude, and Midjourney that is now pulling in $3 million a day and has only one other employee - his brother. We're going to see more stuff like this. The benefits of AI will concentrate into fewer hands.
