If your business relies on video calls, messaging apps, or mobile devices, you are at risk for a new kind of attack.
In this episode of IT Visionaries, host Chris Brandt sits down with Christine Gadsby, Chief Security Officer at BlackBerry, to explore how AI, deepfakes, and weakened telecom infrastructure are reshaping the modern threat landscape.
Christine explains why enterprises can no longer trust what they see or hear, how metadata has become one of the most valuable intelligence sources for attackers, and why encryption alone is no longer enough to protect high-risk communications.
She also breaks down how nation-state groups like Salt Typhoon infiltrate global telco networks, exploit unpatchable 2G and 3G protocols, and use AI to refine attacks in real time.
