Internet Attacked! (Did Anyone Notice?)

Tuesday marked the fourth anniversary of "Safer Internet Day," a 40-country effort to raise awareness about computer and Internet security. But the day probably didn't feel too safe for the dozens of unheralded technologists responsible for defending the World Wide Web against one of the most concerted attacks against the Internet's core since a similar assault in 2002.

Details about the sources, size and methods used in the attack are still trickling in, but like the celebration of Safer Internet Day, it's not clear that anyone using the Web at the time even took notice. That's largely a good thing, and I'll explain why later in this post.

At around 7 p.m. ET on Monday, three of the Internet's 13 "root servers" -- the computers that provide the primary roadmap for nearly all Internet communications -- came under heavy and sustained attack from a fairly massive, remote-controlled network of zombie computers. These are machines infected surreptitiously with programs that allow criminals to control them remotely. The zombies were programmed to try to overwhelm several of the root servers with massive amounts of traffic.

Among the apparent targets was a root server controlled by the Department of Defense Network Information Center. There is also evidence to suggest the attackers targeted the servers responsible for managing the stability of the ".uk" and ".org" domains.

A number of technologists I spoke with who helped defend against the attack said it's too early to say definitively where the attack came from, but this perspective from an operator responsible for maintaining one of the root servers suggests that South Korea, China and the United States were the biggest source of computers used in the attack (the initial analysis suggest that 13 percent of machines involved in the attack were located here in San Francisco, the site of the RSA Security Conference, from which I'm currently blogging.)

In the news coverage so far, theories about the motives behind the attack varied widely, from speculation that it was just hacker mischief to notions that it was cooked up by curious criminals bent on testing their ability to extort the many wealthy and powerful interests that rely on a functioning Internet.

The truth is that no one but the attackers knows the true reason. Paul Levins, vice president of the Internet Corporation for Assigned Names and Numbers (ICANN) -- the entity charged with, among other tasks, coordinating responses among root server providers in such attacks -- said it would likely be at least a week before the more meaningful facts come out.

"This is a fact based community, and we're waiting for the facts to come in after the analysis before we can make committed statements about what the origins were, and its intended targets," Levins said.

This attack highlights a couple of important but often overlooked points, one dark and troubling, and the other somewhat more hopeful. First, the tools and resources used by organized cyber criminals -- namely hacked personal computers that can be remotely controlled by attackers -- are so abundant that they've become virtually disposable. Experts estimate that at any given time there are tens of millions of hacked personal computers that are used in attacks or, more commonly, in sending spam and hosting phishing Web sites.

On the other hand, the fact that there is scant evidence that anyone surfing the Web at the time of the attack even noticed is testament to the resiliency of the global Internet infrastructure, as well as to the swift action on the part of the technologist and experts charged with maintaining the network most of us have come to take for granted.

Not that you can ever have enough security and capacity to handle these types of attacks. The various organizations that operate the 13 root servers are constantly upgrading bits and pieces of their systems to make them more robust and resilient, and one root-server operator -- Verisign Inc. -- is announcing Thursday that it plans to spend $100 million over the next three years to achieve a tenfold increase in its capacity to handle Internet traffic requests.

Nvidia Fails The Vista Test

Nvidia is scrambling to improve the low performance of its graphic-card drivers on Windows Vista.

The maker of the GeForce graphic processors and related daughterboard products has received lots of flack from gamers who say their computer games crashed as a result of Nvidia drivers that have proven to be incompatible with Microsoft's latest operating system.

Nvidia has acknowledged that its Vista drivers haven't performed as well as they should, and said in an e-mail on Wednesday that driver development for Vista is "the highest priority in our company."

"We are working diligently to make sure we achieve and maintain the level of driver quality and reliability that Nvidia is known for," Nvidia spokesman Brian Burke said. "Over the coming weeks, Nvidia and our partners, along with the industry will continue to update Windows Vista drivers to ensure maximum performance on 3D applications and add feature support."

Current Nvidia drivers designated as compatible for Vista include the v96.85 for GeForce FX Series, the v97.46 for GeForce 6 and GeForce 7 Series, and the v100.59 beta driver for GeForce6, GeForce 7 and GeForce 8800.

To pressure Nvidia into action, one customer has launched a website to gather people interested in filing a class-action suit against the Austin, Texas, company. As of Wednesday, had more than a 1,000 registered users.

The anonymous creator of the class-action site insisted in a posting that he wasn't in it for the money. Instead, he promised to take the site down if Nvidia issued a public apology, provided a release date for stable drivers, and offered a token gesture. "A stupid T-shirt, game or rebate certificate -- not asking for a full rebate... but some amount -- would really go a long way."

Nvidia is not the only company to experience problems with Vista. Applehas said on its Web site that none of the Software that it's made available for the Windows environment has been updated for Vista.

MySpace reaches deal with Vodafone in UK

Vodafone Group is counting on the social networking site to drive its UK customers to use their mobile phones for more than just talking. The two companies have struck a deal to distribute software for updating a MySpace user profile from a mobile phone, the companies has announced.
The agreement is the first MySpace, which is owned by News Corp., has reached with a European carrier, says a MySpace spokesman. It calls for Vodafone to ship an application on new mobile phones it sells that will allow MySpace users to email, blog, manage their community of friends and post comments to other users' profiles.

The application, which will also be available for download, will be launched before the end of the year for UK users, the companies say. Pricing for use of the application has not been set, says a Vodafone spokesman.

The agreement could help Vodafone nudge slow overall revenue growth in Europe, by drawing on the MySpace's popularity to boost use of mobile data services.

Vodafone saw growth in mobile data services revenue accelerate in the fourth quarter, but the total still lagged far behind revenue from voice services.

MySpace counted 90 million unique visitors worldwide in December, says the spokesman. Vodafone has about 16.9 million customers in the UK.

MySpace launched a similar deal in the US in December with Cingular Wireless. Cingular subscribers can download a Java application that lets them manipulate MySpace for US$2.99 per month plus standard use charges.

Secondly Don't download any crack , any unofficial stuff for vista...that can cause harm to your computer. And one of the most thing that there are so many who still have confusion regarding version of Windows Vista...Well there are only 5 version of Vista...

These are only versions Windows Vista version like Windows Vista final or like that...Whenever you'll buy any copy of Windows Vista it'll has all version in it. You can install any version by serial key provided by that geniun copy. Only that copy will decide which version to install...becauz you can install any version from one copy but all have different serial key...and after installing you'll have to activate that copy from Microsoft server.....

So download anything..get a geniun copy....becauz geniun is best and 100% harmless...
