Tools for processing Certificate Transparency Log data of "certspotter" published
The Austrian Energy CERT and the GovCERT Austria monitor the Certificate Transparency Logs ("CTL") for their constituents' domains. These Logs contain any newly issued server certificates and monitoring those lists allows for timely detection of abuse. Our processing chain of this data involves several steps which can be useful for other CERTs and security teams. Our experience gained on the processing of this kind of data as well as code will also be incorporated in the further development of IntelMQ.
The tools are published on our GitHub page.
