Reactive measurement using certstream

vishalmohanty opened this issue · 1 comments

https://certstream.calidog.io/ shows the certificates issued on a live basis from the CT logs.

For the domains for which certificates are being issued, perform A lookup (if it is not a wildcard certificate like *.example.com) and NS lookup.

The idea is to flag DNS hijacking attempts by tracking changes to NS records and IP addresses.

Will be taken up under different project.
