It looks like a pretty big DDoS attack is being carried out against several well known anti-spam groups, including Spamhaus, SURBL and URIBL. The Rules Emporium site that hosts additional (and very useful) rules for SpamAssassin is also not available at this moment – I don’t know if they are under a DDoS attack as well.
The attacks seem to be similar to those carried out against BlueSecurity last year, with the Storm malware. Storm is a botnet that can do basically anything and, starting from DDoS attacks to sending spam.
It looks like some anti-spam groups managed to get the attack(s) under control, let’s hope the things will stay that way.
On the other side – this looks like the anti-spam tools are doing their job because spammers seem to be desperate when they launch DDoS attacks (otherwise they would just keep sending spam, instead of using their resources this way).I will be teaching next: Web App Penetration Testing and Ethical Hacking - SANS Munich July 2019
