AI Is Oversharing and Leaking Data - Sounil Yu - PSW #865

Sounil Yu joins us to kick things off with AI defenses: Enterprise AI search tools like Copilot for Microsoft 365 lack the in-depth access controls required to ensure that query responses align with the user’s need-to-know boundaries. Without proper controls, these tools accelerate the discovery of improperly secured sensitive files within the organization. Knostic’s solution ensures that enterprise data is safeguarded without slowing down innovation. By automating the detection and remediation of LLM data exposure, Knostic helps organizations mitigate the security, privacy, and compliance risks associated with AI chatbots and enterprise search tools.

In the security news: The controversial pick for National Cyber Director, the not-so-controversial pick to lead CISA, complete with funding cuts, the controversial ESP32 backdoor that is not a backdoor but hidden features, Dark Storm takes down X, interesting use cases for LoRa, using AI to get your dream job, details on the biggest crypto heist in history, an EDR bypass and a 404 error, slipping through the cracks in CVSS, old school vulnerability disclosure in 2025, Rayhunter, a pen test that should not have been, JTAG and your Flipper Zero, a Linux webcam was used for what now?, and "Spatial-Domain Wireless Jamming with Reconfigurable Intelligent Surfaces"!
