Hallo Stefan,
Michael has informed me that you have patches for the addition of the 3CORESec lists to the ipblocklist function in IPFire in your git repo.
Unless you have a problem with it, I would plan to take those patches and submit them together with the Abuse.ch Botnet C2 IP Blacklist that was mentioned in the June Conf Call, adding the tag that the 3CORESec patches were provided by yourself.
Regards,
Adolf.
