(Reuters) – The FBI’s arrest this week of 16 people who allegedly participated in high-profile cyber attacks is providing a treasure trove of information and will lead to further arrests, a U.S. law enforcement official told Reuters on Thursday.

The crackdown — on members of the group Anonymous — was the biggest reaction so far by U.S. authorities to a string of cyber attacks, and was meant to serve as a deterrent to others who may be considering joining the cause.

The arrests spanned nine states and the District of Columbia. FBI agents also executed more than 35 search warrants, seizing computers and other records. Those arrested could try to strike plea agreements offering to provide information to win more lenient treatment.

Some private cybersecurity specialists have questioned whether the raids will have much lasting impact.

But the law enforcement official said, “This is the good example of a significant event that successfully removed a number of individuals from being part of the problem and will certainly lead to information that will result in locating other subjects.” The official declined to be further identified while speaking about an ongoing law enforcement investigation.

Members of Anonymous mounted attacks last year against eBay’s PayPal as well as Visa and Mastercard after the companies severed their relationships with the WikiLeaks organization. The attacks included flooding the sites with data trying to render them inoperable.

The arrests included members of Anonymous at various levels of the loose-knit organization, the official said. The official declined to comment on whether they knew each other.

While attacks by Anonymous and related “hacktivist” groups have drawn wide attention, other cyber crimes aimed at espionage are a higher priority for the FBI. The latter have included intrusions at Google, Lockheed Martin and the International Monetary Fund.

“We didn’t pull resources away from those higher priority cases to work this,” the official said.

It remains an open question whether the arrests will have the desired deterrent effect. Anonymous and another hacking group, Lulz Security, issued a statement on Thursday saying they would continue their efforts.

“I think they (the FBI) are trying to send a signal that this isn’t cost-free in the hopes that it will scare off some of the others. If we’re lucky it will work,” said James Lewis, a cybersecurity expert with the Center for Strategic and International Studies think tank.

The law enforcement official said that people allegedly involved in the cyber attacks probably did not realize the risks of prison time and that prosecutors would likely seek stiff sentences. Those arrested, if convicted, could face up to 10 years in prison for trying to damage a protected computer.

“They’re probably not the types of people who have been prepared for any time in jail. This is not a joke,” the official said. “The reality of the fact that this is both a crime and that people will be actually doing time in jail I think really hasn’t sunk in to a lot of people who are getting involved in these activities.”

Lewis said one possible benefit from the cyber attacks is that it will lead network and website administrators to beef up their security.

“These guys exploit poor configuration, and that’s the simplest thing to fix but there’s just so much of it out there it will take a while,” Lewis said.

Your laptop’s battery is smarter than it looks. And if a hacker like security researcher Charlie Miller gets his digital hands on it, it could become more evil than it appears, too.

At the Black Hat security conference in August, Miller plans to expose and provide a fix for a new breed of attack on Apple laptops that takes advantage of a little-studied weak point in their security: the chips that control their batteries.

Modern laptop batteries contain a microcontroller that monitors the power level of the unit, allowing the operating system and the charger to check on the battery’s charge and respond accordingly. That embedded chip means the lithium ion batteries can know when to stop charging even when the computer is powered off, and can regulate their own heat for safety purposes.

When Miller examined those batteries in several Macbooks, Macbook Pros and Macbook Airs, however, he found a disturbing vulnerability. The batteries’ chips are shipped with default passwords, such that anyone who discovers that password and learns to control the chips’ firmware can potentially hijack them to do anything the hacker wants. That includes permanently ruining batteries at will, and may enable nastier tricks like implanting them with hidden malware that infects the computer no matter how many times software is reinstalled or even potentially causing the batteries to heat up, catch fire or explode. “These batteries just aren’t designed with the idea that people will mess with them,” Miller says. “What I’m showing is that it’s possible to use them to do something really bad.”

Miller discovered the two passwords used to access and alter Apple batteries by pulling apart and analyzing a 2009 software update that Apple instituted to fix a problem with Macbook batteries. Using those keys, he was soon able to reverse engineer the chip’s firmware and cause it to give whatever readings he wanted to the operating system and charger, or even rewrite the firmware completely to do his bidding.

From there, zapping the battery such that it’s no longer recognized by the computer becomes trivial: In fact, Miller permanently “bricked” seven batteries just in the course of his tinkering. (They cost about $130 to replace.) More interesting from a criminal perspective, he suggests, might be installing persistent malware on the chip that infects the rest of the computer to steal data, control its functions, or cause it to crash. Few IT administrators would think to check a battery’s firmware for the source of that infection, and if undiscovered the chip could re-infect the computer again and again.

“You could put a whole hard drive in, reinstall the software, flash the BIOS, and every time it would reattack and screw you over. There would be no way to eradicate or detect it other than removing the battery.” says Miller.

That attack would require finding another vulnerability in the interface between the chip and the operating system. But Miller says that’s not much of a barrier. “Presumably Apple has never considered that as an attack vector, so it’s very possible it’s vulnerable.”

And the truly disturbing prospect of a hacker remotely blowing up a battery on command? Miller didn’t attempt that violent trick, but believes it might be possible. “I work out of my home, so I wasn’t super inclined to cause an explosion there,” he says.

In fact, the batteries he examined have other safeguards against explosions: fuses that contain an alloy that melts at high temperatures to break the circuit and prevent further charging. But Miller, who has worked for the National Security Agency and subsequently hacked everything from the iPhone to virtual worlds, believes it might still be possible. “You read stories about batteries in electronic devices that blow up without any interference,” he says. “If you have all this control, you can probably do it.”

Miller, currently a researcher with the consultancy Accuvant, isn’t the first to explore the danger of explosive batteries triggered by hackers. Barnaby Jack, a researcher for with antivirus giant McAfee, says he worked on the problem in 2009, but he says he ”benched the research when I didn’t succeed in causing any lithium ion fires. Charlie has taken it a lot further and surpassed where I was at the time.”

Miller says he’s received messages from several other researchers asking him not proceed with the battery work because it could be too dangerous. But Miller has worked to fix the problems he’s exposing. At Black Hat he plans to release a tool for Apple users called “Caulkgun” that changes their battery firmware’s passwords to a random string, preventing the default password attack he used. Miller also sent Apple and Texas Instruments his research to make them aware of the vulnerability. I contacted Apple for comment but haven’t yet heard back from the company.

Implementing Miller’s “Caulkgun” prevents any other hacker from using the vulnerabilities he’s found. But it would also prevent Apple from using the battery’s default passwords to implement their own upgrades and fixes. Those who fear the possibilities of a hijacked chunk of charged chemicals in their laps might want to consider the tradeoff.

“No one has ever thought of this as a security boundary,” says Miller. “It’s hard to know for sure everything someone could do with this.”

Rather than rest on their keyboards after being kicked off Google+, the hacking group known as Anonymous has created a holding page for AnonPlus, a “new social network where there is no fear…of censorship…of blackout…nor of holding back.”

Unlaunched the social networking site may be, Anonymous does promise that everyone will be able to create a profile on the account—hacker or not. Another string to add to our social networking bow? It looks like it. Anonymous writes that “we will not be stopped by those looking to troll or those willing to stop the spreading of the truth.”

As well as deleting their Google+ profile on counts of violating their community standards, it looks as though Google is taking a hard stance on hacking and has also revoked access to their Gmail account.

Starting a social networking site from the ground up will take time; something Anonymous says will not happen “overnight.” Until then, I guess we can start the rumormill churning as to what “features” their site will offer—maybe a poke function that takes down random governments?

Chuck Bittner is one of the most prominent advocates for adding accessibility to videogames.

Chuck Bittner would love to saddle up and lasso some lawbreakers in Red Dead Redemption. But the videogame’s controls are impossible for him to use.

Bittner has quadriplegia, a type of paralysis that limits the functionality of his arms. His hands can only reach certain buttons on standard Xbox 360 and PlayStation 3 game controllers — he can’t use two joysticks at once, for example.

It’s not that Bittner, a New Hampshire resident who grew up on Nintendo and Sega, can’t play games at all. The 36-year-old gamer can do battle in Bethesda Softworks’ first-person shooter Brink, for example, which is just as complex as Rockstar Games’ Wild West adventure.

Why? Unlike Red Dead Redemption, Brink allows players to fully remap the game’s control scheme, the layout that determines which button is assigned to a certain action. It’s a common feature of PC games, but not so much on the Xbox.

By tweaking the button layout in Brink and other games that allow such customization, he can hold the controller in his hands and push the buttons with his face.

“[Button customization] truly would help many disabled gamers … enjoy games more fully,” said Bittner — who goes by the handles AskACapper and ONLYUSEmeFACE — in an e-mail to Wired.com.

Relatively simple and inexpensive to implement, button-customization functionality is just one of many ways gamemakers can make their products more accessible for players with physical disabilities. And it’s not just people born with medical problems who could potentially benefit from the implementation of accessibility standards: Genetic diseases and injuries can affect anybody at any time.

 

“We have ticking time bombs in our DNA,” said Mark Barlet, co-founder of AbleGamers, a nonprofit that has been agitating for gamers with disabilities. “A bad day at work or a split-second at a stoplight on the way to the store and your life could change.”

Barlet, who has limited use of his legs because of a spinal cord injury he incurred while on active duty at Andrews Air Force Base near Washington, D.C., says button remapping is just the tip of the iceberg. As games get more complicated, poor design choices can make them difficult even for gamers without disabilities.

“So many games are using button combinations that make it almost impossible for all but the most practiced able-bodied person to play a game, much less a disabled person,” Barlet said in an e-mail. “Just because you can use all the buttons at once does not mean you should.”

Pushing for Accessibility

Brink player Bittner is doing his damnedest to raise awareness about the difficulties faced by disabled gamers and has started a petition to get game developers to add accessibility features.

He’s probably the most high-profile gamer calling for increased accessibility. A fellow gamer even wrote a song about him, immortalizing Bittner’s quest in a YouTube video (above). “You see our friend Chuck/He dreams of Kinect/But he suffers from the quadriplegic effect,” sings the songwriter, who goes by Typhoon Boon.

Despite the obvious benefits to disabled gamers, it’s not that easy to get developers to commit to the cause.

“These are not features that nobody has ever done before, or features that need lots of exploration and research,” said game designer Matthew Burns, who has worked on titles in the Call of Duty and Halo series, in an e-mail. The problem, he says, is that accessibility options are often the first thing cut during crunch time, when time and money are at a premium.

Another oft-requested accessibility feature is closed-captioning. Most games include subtitles for spoken dialog, but that’s only half of the auditory experience. In many games, nonverbal sound cues can be essential for success. AbleGamers’ Barlet says text-based representations of a full spectrum of sounds and visual cues would be immensely helpful for the hearing-impaired.

Game designer Reid Kimball, who has worked on titles like Star Wars: The Force Unleashed and Tony Hawk: Ride, said it’s sad how rare closed captioning is in games.

“It’s cheap to develop compared to other game technology,” Kimball told Wired.com in an e-mail. “The players love having it as an option and there’s tons of opportunity to innovate in this space.”

It can take from two weeks to a month for a full-time, professional development team to create a closed-captioning system, which Kimball says is inexpensive for large studios. Portal 2 creator Valve, for example, adds closed captioning to all of its games.

“The technology can be used in subsequent games across the entire studio and it doesn’t age, unlike expensive graphics-rendering technologies,” Kimball said.

But there are still snags in the process, says Matthew Burns, now the head of Shadegrown Games. The detailed nature of closed captions usually means a game must be completely finished before developers can add them, he said. By that point, there’s often no time left in the schedule.

“Most of the games that I have seen finish with barely enough time to put all of the audio in, let alone [closed captioning] on top of that,” he said.

Advocates for accessible games face a tough battle. Even if they can convince a game studio to consider closed captioning or button remapping, those features will likely be the first things to get scrapped when deadlines loom and developers start working 10- to 12-hour days to finish games.

As the industry matures, developers are becoming more aware of accessibility challenges, but it will take more than awareness to cause an industry sea change.

“It will continue to be piecemeal and slow unless a large, influential company took a stand and made a conscientious effort to be better about this stuff across the board,” said Shadegrown’s Burns. “That would be the turning point.”

‘What game creators do not truly understand is that as we get older, we are more likely to be disabled.’

AbleGamers’ Barlet says hardware makers hold the most power. Should Microsoft mandate that all Xbox 360 games ship with certain accessibility options, developers would have no choice but to make them a priority. But he doesn’t see this happening.

“We have high-level contacts at one of the big [hardware makers], and they have shown little interest beyond lip service at pushing content producers to think about accessibility,” he said.

Still, the issue’s not going away.

“What game creators do not truly understand is that as we get older, we are more likely to be disabled,” Barlet said. “We have two wars going on, and our soldiers are not all coming back in the same condition as they left. Those men and women are gamers.”

Google has announced a raft of experiments for YouTube under the banner of “Cosmic Panda”.

The changes revolve predominantly around the interface. Activating the Cosmic Panda will give you a new video-watching and playlist experience, extra page designs and editing tools to customise channels, and the ability to keep watching a video while moving between videos, playlists and channels (though this only works in Google’s own Chrome browser).

In a post on the official YouTube blog, product manager Noam Lovinsky wrote: “While you’re watching your favorite or new videos, we at the ‘Tube are obsessing night and day over how those videos are presented. Our team is constantly experimenting, tweaking and playing with new ways to make your experience exactly what you’re looking for.”

You can activate the Panda by heading over to youtube.com/cosmicpanda, and clicking the big blue “Try it out!” button.

On-Ramp Wireless has invented a new way to transmit Wi-Fi which does not just entail using more power to strengthen the signal, but less (which is one reason why this news is on this website).

Wi-Fi signals become more and more distorted as they propagate through the air, and of course, after a while it becomes too distorted to be usable after 1/20 of a mile due to noise. This basically limits the range to the interior of buildings and this also limits the potential uses of Wi-Fi to applications within buildings as well. Imagine if you could connect wirelessly and even cheaply to someone 45 miles away without using the internet? How about while using less energy? You could also eliminate all of the network cables in the largest buildings cheaply and efficiently.

The transmitter in the image at the top of this page can do all of that.

This transmitter achieves that by utilizing an algorithm that transmits it at the same frequency, but in such a way that it is more resistant to noise so it can propagate through the noisy environment over a 45 mile distance.

Another energy related advantage of this is that it could facilitate fewer smart grid access points due to the fact that traditional access points don’t transmit nearly as far, so more are needed so that more access points are closer to buildings with smart meters.

The smart grid concept involves utilizing computer and network technology to enable power plant operators and residents to more effectively match the power production of power plants with power demand to reduce the imbalance of day and night time power consumption.
