Multimodal AI Expands Both Capability and Attack Surface

5 November 2026

By Sunil Parajuli

Technology teams are moving quickly in multimodal AI security, but useful adoption depends on understanding both the opportunity and the operational risk.

What is changing

Instructions can be hidden in images, audio or documents that a model interprets but a reviewer may miss. Multimodal inputs also carry metadata and sensitive biometric information.

What technology leaders should do

Normalize files, remove unnecessary metadata, scan every modality and apply the same authorization rules regardless of input format.

The practical goal is not to adopt every new capability. It is to choose a clear use case, establish measurable success criteria, and build security and accountability into the system from the beginning.
