Businesses brace for December 2025: Three cybersecurity threats to watch

Press Release, 25 November 2025

As the year winds down, Ramsey Theory Group a cybersecurity and digital-transformation specialist warns that December will bring a dramatic shift in cyber risk. CEO Dan Herbatschek outlines three major threats: fully autonomous AI-driven attacks, advanced business email compromise using deepfakes, and supply-chain infiltrations targeting SaaS and AI systems. According to the forecast, threat actors are poised to use AI agents for end-to-end intrusion from reconnaissance to data theft — without human handlers.

Meanwhile, the holiday season creates a perfect storm for financial fraud: attackers are expected to deploy real-time voice and video clones of executives to trick firms into unauthorized payments. On top of this, as companies rush year-end updates and new AI deployments, lurking vulnerabilities in third-party services, plugins, and identity platforms offer fresh attack vectors. Herbatschek stresses that the defence paradigm must shift — organisations will need to implement “governed defensive AI” and assume that their risk extends beyond their own walls into every connected service.
