Microsoft Expands Security Copilot, Faces Signing Abuse

Microsoft has unveiled a significant expansion of its Security Copilot platform, integrating AI agents designed to automate security operations tasks and alleviate the workload on cybersecurity professionals. This move aims to address the increasing volume and complexity of cyberattacks, which are overwhelming security teams that rely on manual processes. The AI-powered agents will handle routine tasks, freeing up IT and security staff to tackle more complex issues and proactive security measures. Microsoft detected over 30 billion phishing emails targeting customers between January and December 2024 highlighting the urgent need for automated solutions.

The expansion includes eleven AI agents, six developed by Microsoft and five by security partners, set for preview in April 2025. Microsoft's agents include the Phishing Triage Agent in Microsoft Defender, Alert Triage Agents in Microsoft Purview, Conditional Access Optimization Agent in Microsoft Entra, Vulnerability Remediation Agent in Microsoft Intune, and Threat Intelligence Briefing Agent in Security Copilot. These agents are purpose-built for security, designed to learn from feedback, adapt to workflows, and operate securely within Microsoft’s Zero Trust framework, ensuring that security teams retain full control over their actions and responses.
