Thread: Massive DDOS attacks on Spamhaus threaten Internet connectivity

the first heard of on front page of online edition of new york times:

the dispute started when spam-fighting group, called spamhaus, added dutch company cyberbunker blacklist, used e-mail providers weed out spam. cyberbunker, named headquarters, five-story former nato bunker, offers hosting services web site “except child porn , related terrorism,” according web site.

so-called distributed denial of service, or ddos, attacks have reached unknown magnitudes, growing data stream of 300 billion bits per second.

“it real number,” [patrick gilmore of akamai] said. “it largest publicly announced ddos attack in history of internet.”

the spammers being protected cyberbunker make usual claims groups spamhaus vigilantes trying impose on freedom-loving types want send more trash , phishing ploys designed defraud naive , unsuspecting. manages mail services myself , few clients, i've spent many many hours fighting spammers , welcome existence of groups spamhaus. whether use spamhaus database, or databases of other similar organizations, entirely mail provider. spamhaus has wide-ranging effect since default set spamassassin uses of spamhaus's lists. since sa developers run tests of validity of rules distribute, data spamhaus provides must have shown worth on time.

rather different type of ddos attack trying flood entity's servers traffic generated botnets. apparently uses method of sending queries dns servers spoofed source address makes traffic appear coming machines @ spamhaus. dns servers send replies spamhaus machines.

if running dns server publicly visible, not authoritative domain, should check logs see if have been inadvertently converted amplifier attack. servers authoritative have accept queries anywhere on internet. if run publicly-visible server needs handle queries limited range of hosts, make sure have locked down configuration server reply hosts , no others.

cyberbunker brags on web site has been frequent target of law enforcement because of “many controversial customers.” company claims @ 1 point fended off dutch swat team.


“dutch authorities , police have made several attempts enter bunker force,” site said. “none of these attempts successful.”
