DESCRIPTION LAST UPDATED: 2024-09-10
DEFAULT SEVERITY: LOW
This report is the aggregation of a variety of different Block/Deny list providers, for end-users’ reference.
The purpose in sharing this information is to alert end-users that specific IP addresses of theirs (or an entire subnet) have been flagged by providers as possibly malicious, and different services might be affected because of this listing. We are not responsible for the listing in the report, we are only alerting you to the fact that you appear on a third-party listing.
Any concerns about a listing should be directed to the owner of the blocklist. The presence of data from a block list owner does not constitute any form of endorsement by Shadowserver. We are only informing of the fact of the listing.
The option to remove any system from a block list will vary by the provider. Some will have a well documented process, and some will demand payment for removal – note, we do not approve of the “payment for removal” practice.
Note that all timestamps are in UTC+0.
You can learn more on the report in our Block List 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.
