Microsoft Sinkhole Events Report

LAST UPDATED: 2022-06-27

This report identifies the IP addresses of all the devices that were reported to Shadowserver from Microsoft after communicating with Microsoft non-HTTP sinkhole servers. Sinkholing is a technique whereby a resource used by malicious actors to control malware is taken over and redirected to a benign listener that can (to a varying degree) understand connections coming from infected devices.

Only infected systems or security researchers should be seen in this list.

Report format is the same as Sinkhole Events Report

You can learn more on the report in our Sinkhole Events Report tutorial.

You can learn more on our reports in general in our Overview of Free Public Benefit Shadowserver Reports presentation, which also explains example Use Cases.
