Microsoft 365 Copilot Prompt Injection Threats in Enterprise

Microsoft 365 Copilot Prompt Injection Threats in Enterprise

ATLAS OWASP MEDIUM Moderate risk · Monitor closely ▲ 6.5 Microsoft Security Blog

Microsoft has released a structured investigator playbook for reconstructing AI-related activity across Microsoft 365 Copilot and Azure AI services, addressing the challenge of converting raw telemetry into coherent incident timelines. The playbook targets threats already observed in enterprise deployments, including prompt injection attempts and unauthorized data access, and operationalizes a scope–context–signal methodology across Purview, Defender, and Sentinel. This guidance directly supports security teams responding to AI-specific incidents where unstructured telemetry has previously hindered attribution and impact assessment.

Anthropic Claude Code Prompt Injection Leaks Secrets

Anthropic Claude Code Prompt Injection Leaks Secrets

ATLAS OWASP HIGH Significant risk · Prioritise patching ▲ 9.1 Microsoft Security Blog

Microsoft Threat Intelligence disclosed a vulnerability in Anthropic's Claude Code GitHub Action whereby prompt injection via untrusted GitHub content — issue bodies, PR descriptions, and comments — could cause the AI agent to read sensitive environment variables, including the ANTHROPIC_API_KEY, from /proc/self/environ. The flaw stemmed from inconsistent sandboxing: while subprocess execution paths like Bash were scrubbed of environment variables, the Read tool had no equivalent restriction. Anthropic patched the issue in Claude Code version 2.1.128 by blocking access to sensitive /proc filesystem paths.
