CrowdStrike Falcon AIDR Adds Coverage for Copilot Studio and Claude Code

FIRST LOOK ATLAS OWASP HIGH Significant risk · Prioritise patching ▲ 7.2 CrowdStrike Blog

CrowdStrike has extended its Falcon AI Detection and Response (AIDR) capability to cover Microsoft Copilot Studio agents and Anthropic Claude Code, bringing behavioural monitoring to two fast-growing agentic AI surfaces. This expansion signals that enterprises are actively deploying autonomous agents in production environments that previously lacked dedicated security tooling. Defenders now have a detection layer for these platforms, but the expanded integration surface also introduces new ingestion and telemetry trust boundaries that adversaries may probe.

Prompt Injection Flaws in Salesforce and Microsoft AI

ATLAS OWASP HIGH Significant risk · Prioritise patching ▲ 8.2 Dark Reading

Prompt injection vulnerabilities in Salesforce Agentforce and Microsoft Copilot were patched after researchers demonstrated that external attackers could exploit them to exfiltrate sensitive user data. The flaws highlight systemic risks in enterprise AI agent deployments, where insufficient input sanitisation allows malicious content to hijack agent behaviour. Both vendors have issued patches, but the incidents underscore the growing attack surface introduced by agentic AI systems operating with elevated privileges.
