Spamhaus recently announced a few years ago that they have discovered a company that is pirating various blocklists, relabeling them and selling access to them. Not only is the company distributing the zones, they’re also running a “pay to delist” scheme whereby senders are told if they pay money, they’ll be removed from the lists. The fake company does remove the listing...
Some email blacklists focus solely on allowing their users to block mail from problematic sources. Others aim to reduce the amount of bad mail sent and prefer senders clean up their practices, rather than just blocking them wholesale. The Spamhaus SBL is one of the second type, using listings both to block mail permanently from irredeemable spammers and as short term encouragement for a sender to...

Authorities in Spain have searched the house where SK was staying and seized electronic devices including computers and mobile phones. Brian Krebs has more, including multiple sources that...
Answers about recent DDoS attack on Spamhaus
While much of the attack against Spamhaus has been mitigated and their services and websites are currently up, the attack is still ongoing.

Playing evasion games to avoid traps is...
The CBL website is back on line. It’s possible that your local DNS resolver has old values for it cached. If so, and if you can’t flush your local DNS cache, and you really can’t wait until DNS has been updated then you may be able to put a temporary entry in your hosts file to point to cbl.abuseat.org. You can get the IP address you need to add by querying the nameserver at ns...
Spamhaus has mostly mitigated the dDOS against the Spamhaus website and mailserver, but now the CBL is under attack. They have been working to get that under protection as well, but it’s taking some time. Right now there are no public channels for delisting from the CBL. The Spamhaus Blog will be updated as things change, and I’ll try and keep things updated here as well. UPDATE:...
Late last night I, and a number of other folks, received mail from Spamhaus informing us of a major denial of service attack against their servers. The attack is so bad that the website and main mailserver is currently offline. DNS services, including rsync and the mirrors, are up and running. Spamhaus is working to bring the mailserver and website back up, and are hoping to have it up later...
