Can Hackers Attack A Trains Network?

Security expert Professor Stefan Katzenbeisser of Technische Universität Darmstadt told a security conference in Berlin that the GSM-R which is being installed in train networks makes them vulnerable to hackers.

Katzenbeisser said that the new system was vulnerable to “Denial of Service” attacks and, while trains could not crash, service could be disrupted for quite some time. Speaking to the Chaos Communication Congress he said that Network Rail is currently installing GSM-R across the British railway network.

It uses the similar technical standards to 2G mobile networks and is due to replace older signalling technology in southern England next year, and throughout the whole country in 2014. But train switching systems, which enable trains to be guided from one track to another at a railway junction, have historically been separate from the online world. If they were connected to the internet as they are in GSM-R they could be hit by Denial of Service attacks.

FCC Warns Against Jammers

The U.S. Federal Communications Commission has issued warnings to 20 online retailers offeriing illegal mobile phone jammers, GPS jammers, Wi-Fi jammers and other signal jamming devices, the agency said Wednesday.

The sale and use of devices that jam the signals of authorized radio communications are illegal in the U.S., the FCC said in its enforcement action. The agency will “vigorously” prosecute violations going forward, it stated in a press release.

“Our actions should send a strong message to retailers of signal jamming devices that we will not tolerate continued violations of federal law,” Michele Ellison, chief of the FCC’s enforcement bureau, said in a statement. “Jamming devices pose significant risks to public safety and can have unintended and sometimes dangerous consequences for consumers and first responders.”

Jammers, sometimes used in classrooms, theaters and churches, are prohibited because they can prevent individuals from contacting police and fire departments or family members during an emergency, the FCC said. “Use of jamming devices can place you or other people in danger,” the agency said.

Was Apple’s Victory, Really A Victory?

As we heard this week Apple had won an injunction barring Samsung from selling some of its Galaxy smartphones in Europe.

However, it is likely that an update from Android 2.x to Android 3.0 will resolve the patent issue, which concerns the way photos are viewed on a touchscreen.

According to OS news, only the Gallery application infringes the patent in question, and Samsung has confirmed it will update the software to get around the problem.

“The injunction has been granted due to the method of scrolling in the Gallery. If that’s replaced, there is no more reason to uphold the injunction,” said Bas Berghuis van Woortman, one of Samsung’s lawyers.

The injunction doesn’t come into effect until mid-October, giving the Korean phone maker plenty of time to change the software. OS news points to evidence showing that although Apple entered into battle with three patents and a community design, all but the Gallery patent were thrown out by the judge.

The swipe-to-unlock patent will likely be declared invalid, the judge wrote, specifically referring to the Neonode N1m mobile phone as prior art, which has the exact same unlock method as the Iphone.

Apple’s complaint about the design of Galaxy smartphones was also thrown out, with the judge citing numerous cases of prior art, including the LG Prada. And in the case of the Android GUI patent, the judge cited the Nokia 7710 as prior art.

Although Samsung’s PR firm in the UK hadn’t heard anything about an Android update, Samsung said that it expects only the Netherlands to be affected by the ruling. It said, “[The] ruling is an affirmation that the GALAXY range of products is innovative and distinctive. With regard to the single infringement cited in the ruling, we will take all possible measures including legal action to ensure that there is no disruption in the availability of our GALAXY smartphones to Dutch consumers.

“This ruling is not expected to affect sales in other European markets. We will continue our plans to introduce new products and technologies that meet and exceed consumer expectations. And we will defend our intellectual property rights through the ongoing legal proceedings around the world.”

Beetel Teletech, part of India’s Bharti Enterprises that controls top mobile carrier Bharti Airtel (BRTI.NS), unveiled a tablet computer priced at 9,999 rupees ($220) on Wednesday.

The 7-inch tablet, branded Beetel Magiq, uses Google’s (GOOG.O) Android operating system and supports both 3G and Wi-Fi networks, Beetel said in a statement.

Beetel is one of the largest makers of fixed-line phones in India. A company spokesman said China’s Huawei HWT.UL was their manufacturing partner for the tablet.

India is the world’s second-biggest and the fastest-growing market for mobile phones, although computer penetration is still low.

Apple Inc (AAPL.O) began iPad sales in India in January this year, while Samsung Electronics (005930.KS) launched its Galaxy Tab in India in November last year.

States Subpoena Sprint

Sprint Nextel has been subpoenaed by nine states in connection with antitrust reviews of AT&T’s proposed $39 billion purchase of T-Mobile USA, according to information Sprint posted on the Federal Communications Commission (FCC) website.

In a letter dated June 28 to FCC, Sprint said it had received subpoenas and civil investigation demands from attorneys general in the states of Arizona, Florida, Hawaii, Illinois, Minnesota, New York, Pennsylvania, Texas and Washington, as well as from the Antitrust Division of the U.S. Department of Justice.

Sprint, the No.3 U.S. mobile service, is opposing AT&T’s proposed $39 billion purchase of No.4 U.S. mobile service T-Mobile USA, a Deutsche Telekom AG unit, on the grounds it will give too much competitive power to one company.

Sprint said in its letter that the states have asked the company to provide all the materials it had submitted to FCC regarding AT&T’s deal.

Meanwhile, an AT&T spokesman told Bloomberg that his company had also received subpoenas from the same nine states regarding its proposed T-Mobile transaction.

TSMC May Beat Intel To Market With 3D Chip

Taiwan Semiconductor Manufacturing Co. is competing with Intel to become the first technology firm to offer three-dimensional chips that boost the density of transistors in a single semiconductor by up to 1000 times.

TSMC, the world’s largest contract chip maker, could make its first 3D chips commercially available before the end of 2011, according to a person close to the situation who wishes to remain anonymous.

The time frame for TSMC matches the end of 2011 schedule that Intel has set for the launch of its 3D Tri-Gate chips, which the company expects to be the world’s first commercial 3D chip and the most significant advance in chip technology since the development of the chip transistor in the 1950s.

With several layers of silicon stacked together, a 3D chip can achieve performance gains of about a third while consuming 50% less power. For this reason, 3D chips are particularly well suited to power new generations of mobile devices such as tablets and mobile phones, businesses where Intel has so far failed to establish a significant presence.

“This is definitely a new business opportunity for TSMC,” said Shang-Yi Chiang, senior vice president for R&D at TSMC, in an interview. “We are building a patent portfolio now.”

3D chips are expected to solve a number of problems for chipmakers who are aiming for performance increases in ever-smaller chips. As transistor density rises, the wires connecting them have become both thinner and closer together, resulting in increased resistance and overheating. These problems cause signal delays, limiting the clock speed of central processing units.

“3D chips look more attractive because of their greater density,” Chiang said. “However, it is more difficult to make them because of the testing issues. If you have five stacked dies and one of the dies is bad, you have to scrap the whole thing.”

Support Calls To Help Desks Are On The Rise

At a time when technology is supposed to be getting simpler, less complex and easier to manage, more people are calling help desks for assistance than ever before, according to a new report. That’s one of the findings that HDI, formerly known as the Help Desk Institute, revealed in its recently released 2010 study of help desk trends.

What HDI found is that the number of incidents reported to help desks via chat, e-mail, telephone, self-help systems, social media, the Web and walk-ins is rising, with 67% of all help desk operations experiencing increases in 2010. That’s roughly the same percentage who reported an increase in 2009.

In recent years, many organizations have moved to centralize their help desk operations and establish a single point of contact for workers, said Roy Atkinson, an analyst at HDI, whose members represent a help desk community of about 50,000 people.

Those centralization efforts have improved incident data collection, which helps to explain the spike in reports. Moreover, creating a single point of contact, and offering multiple ways for people to reach the help desk, encourages users to seek assistance, Atkinson said.

While centralization and better record-keeping may explain much of the increase in reported calls, it doesn’t completely explain it. Atkinson said another part of the explanation could be the fact that IT complexity is actually increasing, especially as users seek to connect multiple devices, including mobile phones, tablets and laptops to corporate networks.

Google Dethrones Symbian From Smartphones Top Spot

Google’s Android dethroned Nokia’s Symbian as the global leader in smartphone operating systems in the last quarter of 2010, ending a reign that began with the birth of the industry approximately ten years ago.

The changing of the guard reflects just how quickly Google, which offers its software to phone makers for free, has risen to the top of the smartphone market ahead of Apple’s rapid ascension. Google and Apple have revolutionized the smartphone market in recent years, sending Nokia scrambling.

In the fourth quarter, phonemakers sold 32.9 million Android-equipped phones globally, roughly seven times more than the year-earlier quarter, compared with Symbian’s sales of 31 million, according to Research firm Canalys.

The numbers also highlight Google’s success in battling Apple, whose shipments of its popular iPhone increased to 16.2 million from 8.7 million in the fourth quarter of 2009.

Unlike Apple or Nokia, Google does not make its own phone hardware but instead offers its Android operating system free to other phone makers who can customize it to suit their devices.

As a result, Android has become the standard software for many phone makers. U.S. phone maker Motorola Inc has even managed to stage a comeback of sorts by focusing solely on Android after years of heavy market share losses….. Read More
