Technical Details

what runs on :7680

Microsoft documents TCP 7680 and UDP 7680 for Delivery Optimization peer-to-peer traffic. Delivery Optimization uses HTTP-based content transfers and content validation, while connections to Microsoft services also use standard web ports such as TCP 80 and 443. The IANA registry historically assigns 7680/tcp and 7680/udp the service name pando-pub, but current Windows use is Delivery Optimization.

security overview

This port should generally be allowed only according to the host's Delivery Optimization policy and should not be deliberately exposed or port-forwarded to the Internet. It is not a remote administration interface, but an exposed peer service can disclose or consume update-distribution traffic and increases attack surface; restrict it with the host firewall and network policy.
