In this week’s Cyber Security Brief, Dick O’Brien, Candid Wueest and Brigid O’Gorman discuss the high cost of ransomware, and the emergence of disinformation-as-a-service on underground markets. We also chat about researchers finding a way to steal data from encrypted PDFs, and the bulletproof hosting service housed in a former NATO bunker in Germany that was recently shut down by police. Finally, we discuss the issue of deepfake videos, the problems they could present, and the steps Google and others are taking to tackle them.
