ATM security flaws could be a jackpot for hackers

ATM security flaws could be a jackpot for hackers A security expert has identified flaws in the design of some automated teller machines that make them vulnerable to hackers, who could make the ubiquitous cash dispensers spit out their cash holdings.

Barnaby Jack, head of research at Seattle-based, security firm IOActive Labs, will demonstrate methods for "jackpotting" ATMs at the Black Hat security conference in Las Vegas that starts on July 28.

"ATMs are not as secure as we would like them to be," Jeff Moss, founder of the Black Hat conference and a member of President Obama's Homeland Security Advisory Council said. "Barnaby has a number of different attacks that make all the money come out."

Jack declined to discuss his techniques before the conference. The world's biggest ATM manufacturers include Diebold Inc and NCR Corp. Officials with those companies could not be reached for comment.

Banks may cringe when he speaks, fearing would-be crooks will…

Featured ArticlesTop 10 Hardest Interview Questions
A job interview is no easy task. In fact many job seekers have trouble with the same set of questions. To ease the process of interviewing, we've listed the Top 10 Hardest Job Interview Questions. Focus on these job interview questions, study them, learn them, research them, and ace your next job interview!

1. Why did you get fired/ terminated?
This question is tricky yet needs to be answered with full honesty. The interviewer would want to hear your honesty and your side of the story. Support your answer with a very good explanation. In case you get fired due to legal issues, explain that you were currently working on it and that it does not have anything to do with your performance. Your explanation in your answer is very important; it should be direct and should not contain intersections.

2. Tell me about problems you encountered with Supervisors. Another tricky question that will test how you worked with your superiors. I sugge…

Featured Technology Talk HP introduces the HP Proliant G7 servers

Featured Technology TalkHP introduces the HP Proliant G7 servers Bangalore: After the introduction of the HP ProLiant servers - the DL360 G7 and DL380 G7, HP announced the launch of G7 servers with AMD Operaton in India. Unlike, the DL360 and DL380 which offers a 20:1 greater consolidation ratio, the newly launched HP ProLiant DL165 G7 and HP ProLiant DL385 G7 with rack -optimized servers offer a ratio of 23:1 consolidation. In a cloud based infrastructure a lot depends on the virtual servers function. Rajesh Dhar Director, Industry Standard Servers, HP India, said "G7 is a completely virtual server which has been patented to provide Ethernet."
The HP Proliant severs known as the "magnificent seven" forms a part of the HP Converged Infrastructure portfolio. It incorporates servers, storage, network devices and facility resources which would help companies to channelize their resources towards IT innovation.

Dhar said that "HP had come up with the G7 ProLiant aft…

Toshiba unveils Portege R700 Laptops in India

Toshiba unveils Portege R700 Laptops in India
Bangalore: Japanese technology major, Toshiba has unveiled its new light weight Portege R700 laptops which come with 13.3 inch screen. The laptop has 'Airflow cooling Technology' which will help getting the external air into the laptop and circulate it. The technology co-developed with Intel. The laptop runs with Intel Core i3 and Core i5 processors.

The Portege comes with up to 8GB of RAM and Toshiba claims that the laptop can run up to eight hours on a single battery charge. The Toshiba also has a built-in optical drive and has a "Hard Drive Impact Sensor" that protects the hard drive from shocks and rough usage. The laptop is estimated to cost around Rs. 65,000 - Rs. 75,000 depending on the system specifications.

Shirtmaker N, Toshiba's General Manager for the PC division in India said that "Our engineers have given a best model with all features including high performance ability. We have enhanced the laptop in …

64 GB next gen SDXC memory card launched by Transcend

64 GB next gen SDXC memory card launched by Transcend Bangalore: Transcend is set to introduce the 64GB Class 10 SDXC memory card in India. These next generation standards for SD cards are available at a price of Rs. 15,000.

SDXC, expanded as Secure Digital eXtended Capacity, is developed by the Secure Digital Association (SDA). The capacities of this new series of cards range from 32GB to 2TB. Compared to SDHC standard, the SDXC cards have greater storage facility and fast data transfer rates up to 25MB/s.

The faster data rates ensure there is no lag in recording 1920X1080 full HD videos. It also supports high-speed consecutive shooting at sporting or other fast-motion events. A separate faster speed category rating called UHS (Ultra High Speed) is also on its way.

Earlier this month, Kingston also announced their 64GB SDXC card at a price tag of $500.

Biodiversity's 'Holy Grail' Is in the Soil : Soil-Borne Pathogens Drive Tree Diversity in Forests, Study Shows

Biodiversity's 'Holy Grail' Is in the Soil : Soil-Borne Pathogens Drive Tree Diversity in Forests, Study ShowsScienceDaily — Why are tropical forests so biologically rich? Smithsonian researchers have new evidence that the answer to one of life's great unsolved mysteries lies underground, according to a study published in the journal, Nature.
What determines plant diversity in a forest? It's a question even Charles Darwin wanted to unravel. But most research into forest diversity demonstrates only patterns of species survival and abundance rather than the reason for them -- until now.
A team of researchers led by biologists at the University of Wisconsin-Milwaukee (UWM) has shown that soil-borne pathogens are one important mechanism that can maintain species diversity and explain patterns of tree abundance in a forest.

"We've known for a long time that tree seedlings do not grow and survive well under their mothers or other adult trees of the same species,&qu…

Whiter Clouds Could Mean Wetter Land

Whiter Clouds Could Mean Wetter Land

ScienceDaily — One proposed emergency fix to halt global warming is to seed clouds over the ocean to make them more reflective, reducing the solar radiation absorbed by the Earth. But the scheme could also change global rainfall patterns, raising concerns of water shortages on land. A new study by the Carnegie Institution, in collaboration with the Indian Institute of Science, suggests that altered atmospheric circulation under the scheme in fact could increase monsoonal rains and cause the continents to become wetter, not drier, on average.
Whitening clouds over the ocean to reflect sunlight is one of several geoengineering schemes proposed to counter global warming. The whitening would be accomplished by reducing the size of the water droplets making up the clouds. "Rain clouds, which have big droplets, tend to be grey and absorb sunlight, whereas clouds with smaller droplets tend to be white and fluffy and reflect more sunlight to space,"…

Physics of the 'Bends': New Study Helps Explain Decompression Sickness

Physics of the 'Bends': New Study Helps Explain Decompression Sickness
ScienceDaily — As you go about your day-to-day activities, tiny bubbles of nitrogen come and go inside your tissues. This is not a problem unless you happen to experience large changes in ambient pressure, such as those encountered by scuba divers and astronauts. During large, fast pressure drops, these bubbles can grow and lead to decompression sickness, popularly known as "the bends."
A study in the Journal of Chemical Physics, which is published by the American Institute of Physics (AIP), may provide a physical basis for the existence of these bubbles, and could be useful in understanding decompression sickness.

A physiological model that accounts for these bubbles is needed both to protect against and to treat decompression sickness. There is a problem though. "These bubbles should not exist," says author Saul Goldman of the University of Guelph in Ontario, Canada.

Because they are belie…
