Spanish Law Enforcement Arrests Cyberattack Suspect

Spanish law-enforcement officials have arrested a man allegedly connected to one of the largest Internet attacks ever launched last month, which targeted a spam-fighting site. The officials didn’t release the identity of the suspect and blurred his face in arrest photos on Spain’s Interior Ministry website. However, observers say he is a Dutch citizen associated with distributed denial-of-service attacks against Spamhaus. He was reportedly arrested at the request of the Dutch police and faces extradition to the Netherlands. (PC Mag)(The New York Times)(Gobierno de España Ministerio del Interior)
 

Retaliatory CyberAttack Ends

Dutch hosting provider CyberBunker, which has allegedly been the source of an ongoing and virulent distributed denial-of-service (DDoS) attack against the anti-spam organization Spamhaus, appears to have had its website taken down -- in a DDoS attack. A series of huge attacks were reportedly launched against Spamhaus in retaliation for placing CyberBunker on its spam blacklist. CyberBunker claimed the attacks were collectively launched by individuals and ISPs who have had problems with Spamhaus, an organization whose databases help organizations, including the government and military, block spam messages. Earlier in the week, hyperbolic reports stated the attacks against Spamhaus were causing the World Wide Web to slow appreciably. Upon closer observation, Internet watchdogs reported the congestion was not widespread, but rather centered in the UK as well as Germany and the Netherlands, which is where the bickering groups are based.

Spam Dispute Erupts into Cyberwar

An argument between a spam-fighting organization and a Dutch hosting firm erupted into a series of computer attacks The New York Times characterized as “one of the largest computer attacks on the Internet, causing widespread congestion and jamming crucial infrastructure around the world.” The fracas began after Spamhaus purportedly placed Cyberbunker, a web hosting firm, on its blacklist, which is used by e-mail providers to prevent spam. Spamhaus claims the attacks started 19 March, but claims it has not been deterred from distributing its blacklist. The distributed-denial-of-service botnet attacks against Spamhaus have reportedly caused routine Internet users to have delays when attempting to reach web sites or disruptions in streaming services such as Netflix. The attacks involve a data stream of as much as 300 billion bits per second. The attackers are using spoofed Domain Name System addresses purporting to be from Spamhaus in an attack known as DNS amplification to cripple Spamhaus’s computing infrastructure. Spamhaus has enlisted assistance from CloudFlare, a company that secures websites and helps lessen the effects of distributed denial-of-service attacks. (The New York Times)(Ars Technica)
