High-Traffic Denial-of-Service Amplification Attacks Remain

It seems the exaggerated volume of bad traffic used in politically motivated DDoS attacks last year was not an isolated phenomenon. Distributed denial-of-service attacks that congest Internet connectivity and disrupt online services topped unprecedented levels in 2013, shoving aside stealthier...

Open DNS Resolvers Center Stage in Massive DDoS Attacks

For some perspective on what 300 Gbps of traffic represents, let’s just pretend that your company, as a potential customer, put this massive volume of bits and bytes in front of 20 of the leading Internet service providers. Chances are, all but three or four will tell you “Thanks, but no thanks, ...

Spamhaus DDoS Attacks Triple Size of Attacks on US Banks

So you thought the 100 Gbps distributed denial-of-service attacks against U.S. banks were big? Ongoing attacks against Spamhaus have three times the fury and have affected unrelated online services as collateral damage. Attackers from Dutch webhost Cyberbunker are turning on a firehose of bad...

Cautious Optimism over Google DNSSEC Deployment

Google’s announcement that its Google Public DNS resolution service now supports DNSSEC is being applauded, but experts caution that despite Google’s high profile, this only puts a slight dent in a larger issue. “I think it’s great that Google is getting involved and supporting validation for...

An as-yet unidentified network event caused BIND 9 resolvers to cache an invalid record, subsequent queries for which could crash the resolvers with an assertion failure. Furthermore, AIX BIND 9.4.1 is affected by the following three security vulnerabilities: CVE-2010-0382 - ISC BIND...

Attackers Turn to Open DNS Resolvers to Amplify DDoS Attacks

Although DDoS attacks have been a serious problem for more than a decade now and security staffs have a good handle on how they’re executed and how to handle them, attackers constantly adjust their tactics in order to defeat the best defenses available. One of the more recent tactics adopted by...

Does DNSSEC Really Interfere With SOPA/PIPA?

You’ve of course heard by now that much of the Internet community thinks that SOPA and PIPA are bad, which is why on January 16, Wikipedia shut itself down, Google had a black bar over their logo, etc. This opinion is shared by much of the Internet technical community, and in particular much has...
