Being part of the cybersecurity community means more than simply following the news or reading security research. It is about getting involved, having conversations, sharing experiences, discussing problems, and learning from peers who face similar operational challenges.

On September 1, 2026, OpenAI announced that its Astra model had reached the Critical tier for cyber capability under the company’s Preparedness Framework, a first for its systems.

OpenAI is disclosing both flaws and restricting the capability to vetted testers.

Let’s catch up on the more interesting vulnerability disclosures and cyber security news gathered from articles across the web this week. This is what we have been reading about on our coffee break! Lucky find for him then!
