Just days after hacking the PBS servers, the hacker group that calls itself LulzSec says its is turning its attentions to Sony.

The group, which also claims responsibility for an attack on Sony's BMG Website in Japan over a week ago, said via Twitter that it was "working on another Sony operation" – adding "this is the beginning of the end for Sony."

LulzSec caught the public eye with its attack on PBS, going so far as to insert a false news story on the NewsHour website that rapper Tupac Shakur was still alive and living in New Zealand.

The group says it has never hacked Sony's gaming servers, choosing instead to focus on the company's music services.

Sony has been the target of several hacks since the theft of personal information from over 100 million PlayStation Network and Sony Online Entertainment user accounts in April. Earlier this month CNET reported a group of hackers was planning another wave of attacks against the company.

Those failed to materialize as threatened, though – something that's significant. Sophisticated hackers, like the ones who performed the first attack on Sony, rarely announce their plans in this fashion. LulzSec, via its boasts, may simply be hoping to achieve a little more notoriety in the hacker community – and may have no plans to attack at all.

Given the group's successful (and repeated) attack on PBS this weekend, though, it's a threat that bears watching.

Roughly a year after Voltage Pictures filed suit against alleged pirates of its Best Picture-winning film "The Hurt Locker," the company has updated the complaint – and it's a whopper.

The suit has grown from the original 5,000 users to a record-breaking 24,583, topping the number of people being sued for illegally downloading "The Expendables".

The additional IP addresses cited by Voltage are split between a number of providers. The studio has reportedly reached agreements with Charter and Verizon to identify individual users, but Comcast (which holds more than half of the addresses) has yet to make a similar agreement.

A full version of the amended complaint is below:

While there are a handful of 3D videos on YouTube already, they're anything but cutting edge.

The only 3D format the service supports is anaglyph - requiring the old-school red and blue glasses to see the effects. That's hardly ideal for studios looking to promote upcoming films or publishers looking to showcase 3D video games. But that's all about to change.

Starting today, YouTube and nVidia have struck an alliance that the online video site will be enabled for nVidia's 3D Vision computer graphics cards. The update will initially be available only to users of Firefox 4, though both organizations are planning to expand beyond that.

A good number of nVidia cards are 3D enabled, but users who want to see the effects need to buy the 3D Vision kit (for $149), which includes a pair of active shutter glasses and a receiver to communicate with those glasses.

YouTube puts active 3D in the big time in online video, but it's not the first site to offer it. nVidia's own 3DvisionLive.com currently offers 100 3D videos and over 5,000 3D pictures. With traffic of just 150,000 visits per month, though, it's a drop in the bucket compared to YouTube. 

This week on Variety.com’s tech chat, “Kung Fu Panda 2” visual effects supervisor Alex Parkinson discusses the state of the art in CG animation, the challenges of 3D for CG artists, and how vfx artists on animated movies are pushing the boundaries of their art – sometimes thanklessly.

With a valuation of $10 billion, Zynga is by far the largest private game maker in the industry. Now investors hoping to get a piece of that pie may have their chance.

Tech blog AllThingsDigital reports the company could file for a public offering as early as this week. Once that IPO takes place, the company is widely expected to be the second biggest publicly-traded publisher in the industry, far surpassing Electronic Arts and Take-Two Interactive Software.

Founded by Mark Pincus (and named after his pet bulldog), Zynga is the maker of hit Facebook games like "FarmVille" and "Mafia Wars". The company claims more than 50 million active users per day and is estimated to see revenue this year of over $1 billion.

Though it was valued at $10 billion in its last round of funding, the company could price itself higher in the offering following the breakout success of networking site LinkedIn last week.

It's not the only game company viewing a public offering. PopCap Games, makers of the "Bejeweled" and "Plants vs. Zombies" franchises, has also floated the idea – and says it will be ready to take the jump this year, should market conditions seem right.

“I do think we’ll be ready internally,” says PopCap president David Roberts. “Whether the market is ready remains to be seen. … It has got to be right for us.”

David S. Cohen chats with Eric Roth and Jeff Okun of the Visual Effects Society on the org’s changing role.

When select TV manufacturers announced plans to include a Netflix button on their remote controls, it raised a few eyebrows, but wasn't exactly shocking, given the company's dominance in the streaming video space.

Now Vudu is getting the same treatment – and this time, people are shocked.

Vizio is leading the charge, announcing plans to add a Vudu button to its remotes for selected HDTVs, media players and Blu-ray players. Like the Netflix button, this will instantly launch the streaming site for users.

Wal-Mart owned Vudu obviously has the retail power behind it, but it also has a substantial film library, with more than 20,000 titles available to rent or purchase. While the service hasn't quite struggled, this is one of its biggest steps to achieving wider success – and perhaps be a viable threat to the Netflix model.

There's no word on exactly when the button will be added to the remotes. 

Apple is certainly the biggest music/tech company around, but Amazon has been very clear in its intention to up the stakes in the fight with the company – and today, it threw a haymaker.

Amazon is offering a daily special for Lady Gaga's "Born This Way," offering the entire album as a digital download for 99 cents. That's less than the cost of a single track on iTunes.

In the big picture, it's a short-term nuisance for Apple, which will almost certainly still see massive revenues from the digital sale of the CD. However, Amazon's using this promotion to drive traffic to its Cloud Drive online storage program. (Buyers are encouraged to store their music there – and by buying the under-a-buck CD, their account is automatically upgraded to a 20 GB tier.

Why is that important? Amazon is already fighting Google for users in its cloud storage system – and Apple's entry in the field is seemingly imminent. Promotions like this give Amazon the chance to establish a customer base before the other services get a foothold.

Cloud storage sites traditionally have been like email accounts for users – once they have taken the time to set up the service and use it a few times (or, in this example, have loaded their files to one), they quickly become embedded and are less likely jump to a competing one.

Nothing has been formally announced yet, but if online reports are to believed (and they're coming from reputable outlets) Apple has most of its ducks in a row for its long-awaited cloud music service.

Warner Music Group, Sony Music Group and EMI Group have all reportedly gotten onboard with the Cupertino tech giant, though it's still not certain if the agreements are in principle or if they've been signed. The status of a deal with Universal Music Group is unclear.

The partnership with at least three of the four major music labels gives Apple an advantage over Google and Amazon in the growing fight for cloud-based music services. Both of those companies have found themselves spending time trying to retroactively soothe the giants instead of locking in customers before Apple joins the fray.

Amazon, for example, went on a peace keeping mission almost immediately after unveiling Cloud Drive, meeting with executives to discuss deal terms.

While neither Amazon nor Google is a company to be taken lightly, Apple automatically has an advantage in the music space. The company has over 200 million credit cards on file and users have downloaded over 10 billion songs since the launch of iTunes.

By creating a "jukebox in the sky" with cloud technology, the company could easily transfer previous purchases to its data center, letting users access their entire catalog on a variety of devices – without having to worry about uploading them (as users must do with Google and Amazon's service) and without having to manually add them to multiple devices as they do today.

Apple may be late to this fight, but it was late to the portable music hardware market as well – and that doesn't seem to have been too impactful on the company.

We're about two-and-a-half weeks from the start of E3, but if you weren't able to get a pass to the video game industry's annual trade show, you'll still be able to see some of the big moments.

Spike TV and Microsoft have struck a deal for the network to broadcast the Xbox 360 E3 media briefing on June 6.

Media briefings are where the big console news of the coming year is unveiled. Last year, Microsoft announced Kinect and the revamped Xbox 360 as well as its streaming partnership with ESPN. This year's telecast will air live at 12:30pm ET

Incidentally, if you've got G4 on your cable system, you can see all of the media briefings. The game-themed channel will once again offer wall-to-wall coverage of the show, including live broadcasts of the keynotes from Microsoft, Sony and Nintendo – as well as from all of the third-party publishers.
