I received 4 spam e-mails earlier that housed 4 links pointing to zip files on 4 sites housed on rZone.de (Cronon) IP space - all of the files contain trojans - more on that later.
As I normally do, I tried dropping the address listed in the net-block info an e-mail (firstname.lastname@example.org and email@example.com), sadly it seems they don't want to receive abuse reports;
And yep, I tried sending via both my Malwarebytes address and my normal it-mate.co.uk address.
Until they stop rejecting abuse reports, I'd strongly recommend you put a block on their IP range.
The offending URLs, for those wondering;
