The Threat: OWA Vulnerability Exploitation

Russian threat actors have been observed exploiting a now-patched vulnerability in Microsoft OWA to target government entities, telecommunications, financial, hospitality, and aerospace sectors in the U.S. and Europe. This activity started on July 22, 2026, and highlights the importance of cybersecurity for all businesses, including small ones.

Why It Matters to Small Businesses
