Inbound connection in port 135 (UDP/TCP) is not blocked in Windows firewall
Microsoft''s "DCOM (Distributed Component Object Model) Service Control Manager" running on the user''s computer utilizes the port 135. Port 135 exposes where DCOM services can be found on a machine. Hacker tools such as "epdump" (Endpoint Dump) can immediately identify every DCOM-related server/service running on the user''s hosting computer and match them up with known exploits against those services. Therefore, port 135 should not be exposed to the internet and must be blocked.
Follow the below steps to resolve the misconfiguration.
Step 1: Open the Control Panel
Step 2: Click on Windows Firewall/ Windows Defender firewall
Step 3: Navigate to advanced settings.
