Ask Claude or ChatGPT to write a phishing email and it politely refuses; pull the right open-weight model onto your own laptop and that refusal layer simply does not exist in many cases.
Andy brings his InfoSecurity Europe session to the show, and Eric Siron joins to walk through how threat actors run local LLMs on their own hardware to generate targeted spear phishing at scale, in any language, with no internet connection and no guardrails.
The guys break down what the attack workflow actually looks like, why these capabilities never disappear once a model is downloaded, and where the real defensive line sits. Spoiler: "spot the typo" awareness training is dead, and verification culture plus strong email authentication is what carries the load now.
