Key point: Gartner identifies four critical threats, including deepfakes and prompt injections, where attackers have technical and temporal advantages.
Gartner analysts warn of four critical threats where attackers currently have advantages over defensive measures. These include deepfakes and prompt injections – attack vectors that organizations must increasingly address.
Gartner analysts have identified four critical threats where attackers currently exploit structural advantages against established defense mechanisms. The list includes deepfakes – synthetic audio and video content that deceptively imitate authentic identities or statements – as well as prompt injections, an attack technique against large language models and AI systems.
For Chief Information Security Officers, this means that traditional security control points are partly blind to these new vectors. Deepfakes threaten not only the authentication of communication but also trust in visual and audio evidence – a foundation of many forensic and regulatory processes. Prompt injections exploit the gap between human intent and AI model behavior, and can lead to unexpected data disclosure, logic bypass, or manipulation of AI-driven business processes.
Gartner recommends treating these threats as a strategic defensive problem: not only technical controls, but also governance frameworks, process validation, and awareness training must be recalibrated. CISOs should review their security architectures for resilience against these attack classes and build both technical and organizational mitigation measures in parallel.
