Fable 5, GPT-5.6 and the high stakes of AI safeguards. Plus: Agentic ransomware, and ClickFix reigns supreme

When it comes to Fable 5, Mythos 5, and GPT-5.6 Sol, the real story is in the safeguards.

Last week, Anthropic and OpenAI both rolled out some powerful new models. And for perhaps the first time, the protections surrounding these models got almost as much airtime as the models’ themselves.

On this week’s episode of IBM Security Intelligence, Sophie Cunningham, Diego Matos Martins and Jeff Crume join host Matt Kosinski to talk about an emerging paradigm in frontier models: Safety first. What’s gained and what’s lost when security controls take center stage? And just how effective are the ones we’ve developed?

Then, we dive into Sysdig’s report on JADEPUFFER, the first agentic ransomware. But not every security expert agrees with that conclusion. So where do we land?

Plus: ClickFix is the new king of social engineering schemes—and it’s coming for your developers.

Finally, Senior Threat Researcher Itzhak Chimino shares his technical research into UnregStealer, a credential-theft campaign targeting Latin American banks.

All that and more on Security Intelligence.
