Nearly 2,000 Malicious IPs Probe Microsoft Remote Desktop After Single-Day Surge
GreyNoise detected a sudden surge in scanning activity targeting Microsoft Remote Desktop (RDP) services on August 21, with attackers probing for timing vulnerabilities that could expose valid usernames. The reconnaissance activity from approximately 2,000 malicious IP addresses appears designed to enable credential-based attacks. This pattern suggests coordinated preparation for intrusion attempts rather than isolated scanning noise.
Why it matters: Organizations exposing RDP to the internet face immediate reconnaissance risk from attackers mapping valid accounts; security teams should review RDP access controls, network segmentation, and authentication protections today.
