An attack directed at the DNS provider for some of the Internet's larger e-commerce companies--including Amazon, Wal-Mart, and Expedia--took several Internet shopping sites offline Wednesday evening, two days before Christmas.
Neustar, the company that provides DNS services under the UltraDNS brand name, confirmed an attack took place Wednesday afternoon, taking out sites or rendering them extremely sluggish for about an hour. A representative who answered the customer support line said the attacks were directed against Neustar facilities in Palo Alto and San Jose, Calif., and Allen Goldberg, vice president of corporate communications for Neustar, confirmed that at about 4:… Read more

Google is offering a public DNS service (DNS is the address book for Internet domains) that will resolve the domain names you type into a Web browser to servers you want to visit. But that could really give Google a complete picture of who you are. Do you want that? We also chat about the World Cup coming in 3D and the effects of BitLocker encryption being broken.

When you load a website, or use any other fully qualified domain name (ie, www.macfixit.com), the name needs to be resolved to something that your computer can use, such as an IP address. The service that does this is DNS, or "Domain Name System", which is essentially the index or address book for the internet. The DNS network consists of servers and resolvers that work to cache and propagate a distributed hierarchical database of internet names, domains, and subdomains. The resolved IP addresses are sent to the client system (your computer) when you make a DNS request.… Read more
VeriSign, which runs the master database for such domains as .com and .net, says a significant Internet security vulnerability will be closed by 2011, after delays caused by technical aspects of the implementation.
The problem is that DNS, the Domain Name System that translates Internet addresses into numerical values, can be seeded with false values and used to misdirect users. VeriSign told ZDNet on Friday that it will put in place DNSSEC, a protocol that will guarantee the origin and integrity of DNS data for the .com and .net domains, by the first quarter of 2011.

So, Twitter has had a hard time staying up today because of a denial of service attack. But we think we have the answer. And it's available in many spam e-mails for order. We also get in a big, fat argument about whether News Corp. will win or lose by charging for all its news sites. But we can all agree on Whisky.Subscribe with iTunes (audio) Subscribe with iTunes (video) Subscribe with RSS (audio) Subscribe with RSS (video) EPISODE 1036
An attack on the main domain name system registrar in Puerto Rico led to the local Web sites of Google, Microsoft, Yahoo, Coca-Cola, and other big companies being redirected for a few hours on Sunday to sites that were defaced, according to security firm Imperva.
Those sites and others including PayPal, Nike, Dell, and Nokia, were redirected to sites that were black except for messages in hacker lingo saying that the sites had been hacked. However, the sites themselves were not hacked, Amichai Shulman, chief technology officer at Imperva, said on Monday.
