Microsoft 365 runs the day-to-day operations of your business. That also makes it one of the most valuable targets attackers go after. When Teams, SharePoint, Exchange, and Entra ID power collaboration, identity, and data access, even a small visibility gap can turn into a real security incident.

CoreView’s Anatomy of a Microsoft 365 Attack shows how those incidents actually happen. It breaks down how attackers get in, move across a tenant, and maintain access long enough to cause business impact.

The whitepaper walks through the full attack lifecycle — reconnaissance, entry, privilege escalation, persistence, evasion, and outcomes like ransomware or data exfiltration. It focuses on what teams are seeing right now (e.g. password spraying, targeted phishing, etc.). It also reflects the reality of operating Microsoft 365 at enterprise scale with thousands of configuration points, multiple admin surfaces, and a steady flow of third-party and custom integrations.

Each section ends with practical prevention and detection actions you can apply immediately to tight controls, reduce excess privilege, and catch configuration drift before it becomes an incident.

If Microsoft 365 is business-critical for you, this asset gives you a clearer path to reducing tenant risk, improving visibility across workloads, and building resilience without slowing your teams down. Get your copy.
