In this final chapter on analyzing compromised cloud productivity suites, we explored how to tackle security incidents in the two most popular cloud-based productivity suites, Microsoft 365 and Google Workspace. These platforms, crucial for emails, storage, and office applications, are frequently targeted in BEC attacks.
