Server infrastructure — abstract blue digital network

When Microsoft's Own Email Becomes the Weapon

A Microsoft CSP's analysis of notification abuse through CISA SCuBA, MITRE ATT&CK, NIST SP 800-53, and CIS Benchmarks — and what organizations must do now.

Lionel Mosley — ahr-ki-tekt

Lionel Mosley is an IT Consultant, Innovative Thought Leader, and Subject Matter Expert based in Houston, TX — serving organizations nationwide through 4TH AND BAILEY. With over two decades of experience across cloud infrastructure, cybersecurity, Microsoft 365 environments, and enterprise IT governance, Lionel works with organizations from SMBs to large enterprises to build technology architectures that are secure, resilient, and aligned with the frameworks that matter — CISA SCuBA, NIST SP 800-53, MITRE ATT&CK, and CIS Benchmarks.

The ahr-ki-tekt Design Journal is where that work gets documented — frameworks, insights, and analysis published on the open web for the organizations and practitioners who need it most.

"I've spent my career asking 'what if' when everyone else was asking 'how much.' The organizations that survive what's coming will be the ones that asked the right questions before the crisis began."
