Hot Take:

Looks like Microsoft Exchange just got a hybrid makeover, but not the kind you’d want to brag about in the office newsletter. If your organization is still holding hands with an unpatched Exchange server, CISA is basically saying, “It’s not me, it’s you.” Time to patch up that hybrid relationship before it starts ghosting your emails… permanently!

Key Points:

  • CISA issued Emergency Directive 25-02 addressing Microsoft Exchange vulnerabilities.
  • Directive targets Federal Civilian Executive Branch (FCEB) agencies but urges all to patch up.
  • Vulnerability (CVE-2025-53786) affects Microsoft Exchange hybrid deployments.
  • Patching deadline for FCEB agencies is August 11, 2025, at 9:00 AM EDT.
  • April 2025 patch guidance must be implemented to avoid risks.
