Microsoft on Wednesday rolled out an AI-powered security analysis tool to automate incident response and threat hunting tasks, showcasing a security use-case for the popular chatbot developed by OpenAI.

The new tool, called Microsoft Security Copilot, is powered by OpenAI’s newest GPT-4 model and will be trained on data from Redmond’s massive trove of telemetry signals from enterprise deployments and Windows endpoints.

Cybersecurity experts are already using generative AI chatbots to simplify and enhance software development, reverse engineering and malware analysis tasks and Microsoft’s latest move adds several new use-cases for defenders.
