How do you get $45 million from ATMs? Cyberthieves did it in 12 hours

In two digital bank heists that took a total of just 12 hours to pull off, cyberthieves working with ?casher? crews around the world were able to withdraw $45 million dollars in cash from ATM machines in 26 countries.

The new-era cyberheists were plotted over months by hacker masterminds who stealthily infiltrated the computer networks of two credit card processors responsible for pre-paid debit card transactions ? one in India and one in the United States, according to a federal indictment unsealed late Thursday by authorities in New York.

The document details a scheme in which the hackers ? who were not named in the document ? first gained internal access to a critical banking computer system. Then, they raised the balances and maximum withdrawal amounts on a handful of debit card accounts they controlled in what the indictment terms an ?unlimited operation.? Those account numbers and access data were then transmitted to accomplices worldwide ready to use them at ATM machines, the indictment said.

The ?cashers? took the data that was sent to them and then encoded it onto the magnetic stripes of gift cards. With the faked cards, the cashers made more than 40,000 withdrawals averaging more than $1,100 each.

Among the casher teams was a single team of eight New York City men, alleged to have withdrawn $400,000 in the first attack in 750 fraudulent transactions at 140 ATM machines in New York.

That Dec. 22, 2012 attack took just two hours and 25 minutes. But it was only the warm-up to a much larger global attack on Feb. 20, where the same New York casher group scooped up another $2.4 million from 3,000 ATM machines. That attack lasted from 3 p.m. on Feb. 19 to 1:26 a.m. the next morning, according to the indictment.

Seven of the eight New York men are under arrest. But the eighth member and purported leader of the gang ? Alberto Yusi Lajud-Pe?a, also known as ?Prime? and ?Albertico? ? was murdered in the Dominican Republic late last month, not long after fleeing the country, according to authorities who announced the arrests Thursday.

?The defendants and their co-conspirators participated in a massive 21st century bank heist that reached across the Internet and stretched around the globe,? said Loretta Lynch, United States attorney for the Eastern District of New York, in a statement. ?In the place of guns and masks, this cybercrime organization used laptops and the Internet.?

Indeed, the New York City casher crew was just a cog in a much larger ATM machine scam. In the first global attack in December, a total of $5 million was taken in 4,500 ATM transactions in 20 countries in under three hours. In the far bigger attack in February, $40 million was taken in 36,000 ATM transactions across 24 counties in less than 11 hours.

In the first attack in December, hackers gained access to the network of a credit card processor in India that processed transactions for prepaid MasterCard debit cards issued by the National Bank of Ras Al-Khaimah PSC, also known as RAKBANK, in the United Arab Emirates, the indictment says.

In that attack, five RAKBANK accounts were hacked and their withdrawal limits lifted. In the second attack, a US-based processor was infiltrated along with the accounts of 12 MasterCard prepaid debit cards, this time issued by the Bank of Muscat, located in Oman.

During both operations, the hackers maintained access to the computer networks of the credit card processors to keep a close eye on the fraudulent ATM transactions as they were happening ? and to tally the totals so they could be sure how much was taken ? and compare that with how much they received back from the cashers.

After the attack, the casher crews began laundering the money. In one transaction, nearly $150,000 in the form of 7,491 $20 bills, was deposited in a Miami bank account controlled by Mr. Lajud-Pe?a. Members of that group also used the cash to buy expensive watches and cars, including Rolex watches, a Mercedes SUV, and Porsche Panamera. The Mercedes and Porsche were purchased with $250,000 from the scam.

The ATM heists appear to be part of a countertrend among cyberthieves, who generally have moved toward smaller financial cyberscams and away from bigger more dramatic efforts that attract police attention, cybersecurity experts say.

"Pulling off a huge heist might achieve fame and fortune, but it also attracts a lot of unwanted attention,? concluded the 2012 Data Breach Investigations Report, an industry study by Verizon.

That appears to be true in this most recent case. If convicted, the seven defendants face a maximum sentence of 10 years? imprisonment on each of the money laundering charges and 7.5 years on conspiracy to commit access device fraud as well as $250,000 in fines.

Although the indictment says nothing about the masterminds behind the ATM heists, officials say the cyberthefts are still under investigation.

New magnetic graphene may revolutionize electronics

May 10, 2013 ? Researchers from IMDEA-Nanociencia Institute and from Autonoma and Complutense Universities of Madrid (Spain) have managed to give graphene magnetic properties. The breakthrough, published in the journal 'Nature Physics', opens the door to the development of graphene-based spintronic devices, that is, devices based on the spin or rotation of the electron, and could transform the electronics industry.

Scientists were already aware that graphene, an incredible material formed of a mesh of hexagonal carbon atoms, has extraordinary conductivity, mechanical and optical properties. Now it is possible to give it yet one more property: magnetism, implying a breakthrough in electronics.

This is revealed in the study that the Madrid Institute for Advanced Studies in Nanoscience (IMDEA-Nanociencia) and Autonoma Autonomous (UAM) and Complutense (UCM) universities of Madrid have just published in the journal Nature Physics. Researchers have managed to create a hybrid surface from this material that behaves as a magnet.

"In spite of the huge efforts to date of scientists all over the world, it has not been possible to add the magnetic properties required to develop graphene-based spintronics. However these results pave the way to this possibility," highlights Prof. Rodolfo Miranda, Director of IMDEA-Nanociencia.

Spintronics is based on the charge of the electron, as in traditional electronics, but also on its spin, which determines its magnetic moment. A material is magnetic when most of its electrons have the same spin.

As the spin can have two values, its use adds two more states to traditional electronics. Thus, both data processing speed and quantity of data to be stored on electronic devices can be increased, with applications in fields such as telecommunications, computing, energy and biomedicine.

In order to develop a graphene-based spintronic device, the challenge was to 'magnetise' the material, and researchers from Madrid have found the way through the quantum and nanoscience world.

The technique involves growing an ultra perfect grapheme film over a ruthenium single crystal inside an ultra high vacuum chamber whereorganic molecules of tetracyano-p-quinodimethane (TCNQ) are evaporated on the grapheme surface. TCNQ is a molecule that acts as a semiconductor at very low temperatures in certain compounds.

On observing results through an scanning tunnelling microscope (STM), scientists were surprised: organic molecules had organised themselves and were regularly distributed all over the surface, interacting electronically with the graphene-ruthenium substrate.

"We have proved in experiments how the structure of the TCNQ molecules over graphene acquireslong-range magnetic order, with electrons positioned in different bands according to their spin," clarifies Prof. Amadeo L. V?zquez de Parga.

Meanwhile, his colleague Prof. Fernando Martin has conducted modelling studies that have shown that, although graphene does not interact directly with the TCNQ, it does permit a highly efficient charge transfer between the substrate and the TCNQ molecules and allows the molecules to develop long range magnetic order.

The result is a new graphene-based magnetised layer, which paves the way towards the creation of devices based on what was already considered as the material of the future, but which now may also have magnetic properties.

The social needs of young people with cancer | Science Codex

New Orleans, LA ? Research conducted by Xiao-Cheng Wu, MD, PhD, Associate Professor and Director of the Louisiana Tumor Registry at the LSU Health Sciences Center New Orleans School of Public Health, and colleagues, reports adolescents and young adults with cancer may be at higher risk for social isolation and that a substantial proportion of them have unmet social needs that could adversely affect their health. The research is published online in the Journal of Adolescent and Young Adult Oncology. More than 500 participants in the Adolescent and Young Adult Health Outcomes and

Patient Experience (AYA HOPE) Study completed a survey 6-14 months after diagnosis that included questions about two social information needs ? how to talk about their cancer experience with family and friends and meeting other adolescents or young adult cancer patients/survivors. Patients were identified through seven Surveillance, Epidemiology and End Results (SEER) program sites: the states of Iowa and Louisiana; the metropolitan areas of Detroit, Michigan and Seattle/Puget Sound, Washington; and three metropolitan areas in California: Los Angeles County, San Francisco/Oakland, and Sacramento County. The participants were 15 to 39 years old at diagnosis and were diagnosed with cancers prevalent in that age group. The researchers examined such variables as age at diagnosis, gender, race/ethnicity, education, and health insurance status at diagnosis. They looked at clinical factors including treatment (radiation, chemotherapy, and surgery), current general health, overall quality of care, and the number of symptoms experienced in the previous month. Participants were asked about the overall impact of their cancer on specific areas of their lives.

The research team found that social information needs were higher among those who were in their 20s at diagnosis ? with 25% reporting needing help to talk about their cancer. About 43% of those of Hispanic or "other" race/ethnicity expressed a need to meet peer survivors. Those who were not in a support group, had a high number of symptoms or additional illnesses, as well as low perceived quality of care also needed more help.

"Our findings identify subgroups of adolescents and young adults who are most in need of additional social support and suggest targets for clinical intervention," notes Dr. Wu.

Research has shown that cancer may limit these young patients' ability to form new or maintain relationships at a time in their development when peer bonding is the norm. Even when the patient's support network is strong, current friends may not be able to meet psychosocial needs because they do not understand the problems that come with a cancer diagnosis and treatment, further isolating the patient. Existing resources may be unknown, out of their financial reach, or not relevant to these young people.

Suggested interventions include the development of programs capable of providing support at different phases of the cancer experience, providing services for a diverse age range, overcoming geographic and financial barriers and a lack of cultural diversity in the offerings, as well as increasing awareness and access to peer support groups with other cancer patients and survivors. Improving awareness of and access to online connection through social media, as well as help in learning how to share their experiences with loved ones would also bolster support. The researchers say that developing communication tools specifically for them may help these young patients express their needs and gain emotional support from their family and friends. It is also important to educate health care professionals and others about these resources.

"With limited research in this area, understanding which subgroups of adolescents and young adults with cancer are most in need and what they perceive their greatest needs to be is critically important to tailor interventions and support programs for them," notes Dr. Wu, who leads one of the 18 cancer registries in the United States designated as SEER registries by the National Cancer Institute.

Rejuvenating hormone found to reverse symptoms of heart failure

May 9, 2013 ? Heart failure is one of the most debilitating conditions linked to old age, and there are no specific therapies for the most common form of this condition in the elderly. A study published by Cell Press May 9th in the journal Cell reveals that a blood hormone known as growth differentiation factor 11 (GDF11) declines with age, and old mice injected with this hormone experience a reversal in signs of cardiac aging. The findings shed light on the underlying causes of age-related heart failure and may offer a much-needed strategy for treating this condition in humans.

"There has been evidence that circulating bloodstream factors exist in mammals that can rejuvenate tissues, but they haven't been identified. This study found the first factor like this," says senior study author Richard Lee of the Harvard Stem Cell Institute and Brigham and Women's Hospital.

Heart failure is a condition in which the heart can't pump enough blood to meet the body's needs, causing shortness of breath and fatigue, and it is becoming increasingly prevalent in the elderly. The most common form of age-related heart failure involves thickening of heart muscle tissue. But until now, the molecular causes and potential treatment strategies for this condition have been elusive.

To identify molecules in the blood responsible for age-related heart failure, a team led by Lee and Amy Wagers of the Harvard Stem Cell Institute and Joslin Diabetes Center used a well-established experimental technique: they surgically joined pairs of young and old mice so that their blood circulatory systems merged into one. After being exposed to the blood of young mice, old mice experienced a reversal in the thickening of heart muscle tissue. The researchers then screened the blood for molecules that change with age, discovering that levels of the hormone GDF11 were lower in old mice compared with young mice.

Moreover, old mice treated with GDF11 injections experienced a reversal in signs of cardiac aging. Heart muscle cells became smaller, and the thickness of the heart muscle wall resembled that of young mice. "If some age-related diseases are due to loss of a circulating hormone, then it's possible that restoring levels of that hormone could be beneficial," Wagers says. "We're hoping that some day, age-related human heart failure might be treated this way."

Allegiant Flight Attendants Launch Ad and Website to Rename Maurice J. Gallagher Jr. Hall at University of California, Davis Business School ? ?Let?s set an example for future business leaders?

For immediate release?May 9, 2013

Allegiant Flight Attendants Launch Ad and Website to Rename Maurice J. Gallagher Jr. Hall at University of California, Davis Business School ? ?Let?s set an example for future business leaders?

Davis, CA ? Flight attendants at Allegiant Air, members of TWU Local 577, launched a new ad and website urging students and faculty at the University of California, Davis to participate in the renaming of Maurice J. Gallagher Jr. Hall.

The building, where UC Davis School of Management students attend classes, was named after Gallagher, CEO of Allegiant Airlines and former officer and director of ValuJet, following a $10 million donation to the school. The TWU ad, which will run in today?s UC Davis newspaper The California Aggie, features the headline ?Rename Gallagher Hall? and asks:

Shouldn?t the main classroom building be named for a leader who in your opinion has a reputation for high standards and business excellence?

?Let?s honor business leaders who treat employees and customers with respect, while still delivering a profit to shareholders,? said Thom McDaniel, International Vice President of the Transport Workers Union. ?We should name buildings after people who deliver value to customers and the communities they serve, while also representing the best values of the University of California.?

The ad encourages readers to ?join us by adding your suggestion for a corporate leader fitting this profile? at the new website?www.RenameGallagherHall.org.

?This is a step in the right direction for our campus. We need to start naming buildings after people that are community and worker friendly,? said Duane Wright, UC Davis campus chair of UAW Local 2865, the union representing teaching assistants, readers, tutors and other academic workers at the University of California.

Recent news reports about Allegiant have raised concerns about passenger delays, the reliability of the airline?s aging fleet, excessive fees and abrupt cancellation of routes and service to cities formerly served by the airline.

A majority of flight attendants at Allegiant voted in favor of TWU representation in December 2010. More than two years later, flight attendants still do not have a first contract agreement.

The Transport Workers Union of America (TWU) represents 200,000 workers and retirees in commercial aviation, public transportation and passenger railroads, including 11,000 flight attendants. The union is an affiliate of the AFL-CIO.

Biomaterial shows promise for Type 1 diabetes treatment

May 9, 2013 ? Researchers have made a significant first step with newly engineered biomaterials for cell transplantation that could help lead to a possible cure for Type 1 diabetes, which affects about 3 million Americans.

Georgia Tech engineers and Emory University clinicians have successfully engrafted insulin-producing cells into a diabetic mouse model, reversing diabetic symptoms in the animal in as little as 10 days.

The research team engineered a biomaterial to protect the cluster of insulin-producing cells -- donor pancreatic islets -- during injection. The material also contains proteins to foster blood vessel formation that allow the cells to successfully graft, survive and function within the body.

"It's very promising," said Andr?s Garcia, Georgia Tech professor of mechanical engineering. "There is a lot of excitement because not only can we get the islets to survive and function, but we can also cure diabetes with fewer islets than are normally needed."

The research article -- a partnership with Emory's Dr. Robert Taylor and Dr. Peter Thule that was funded in part by the JDRF, the leading global organization funding Type 1 diabetes research -- will be published in the June issue of the journal Biomaterials.

Organizations such as JDRF are dedicated to finding a cure for Type 1 diabetes, a chronic disease that occurs when the pancreas produces little or no insulin, a hormone that allows the transport of sugar and other nutrients into tissues where they are converted to energy needed for daily life.

Pancreatic islet transplantation re-emerged as a promising therapy in the late 1990s. Patients with diabetes typically find it difficult to comply with multiple daily insulin injections, which only partially improve long-term outcomes. Successful islet transplantation would remove the need for patients to administer insulin. While islet transplantation trials have had some success, and control of glucose levels is often improved, diabetic symptoms have returned in most patients and they have had to revert to using some insulin.

Unsuccessful transplants can be attributed to several factors, researchers say. The current technique of injecting islets directly into the blood vessels in the liver causes approximately half of the cells to die due to exposure to blood clotting reactions. Also, the islets -- metabolically active cells that require significant blood flow -- have problems hooking up to blood vessels once in the body and die off over time.

Georgia Tech and Emory researchers engineered a hydrogel, a material compatible with biological tissues that is a promising therapeutic delivery vehicle. This water-swollen, cross-linked polymer surrounds the insulin-producing cells and protects them during injection. The hydrogel containing the islets was delivered to a new injection site on the outside of the small intestine, thus avoiding direct injection into the blood stream.

Once in the body, the hydrogel degrades in a controlled fashion to release a growth factor protein that promotes blood vessel formation and connection of the transplanted islets to these new vessels. In the study, the blood vessels effectively grew into the biomaterial and successfully connected to the insulin-producing cells.

Four weeks after the transplantation, diabetic mice treated with the hydrogel had normal glucose levels, and the delivered islets were alive and vascularized to the same extent as islets in a healthy mouse pancreas. The technique also required fewer islets than previous transplantation attempts, which may allow doctors to treat more patients with limited donor samples. Currently, donor cells from two to three cadavers are needed for one patient.

While the new biomaterial and injection technique is promising, the study used genetically identical mice and therefore did not address immune rejection issues common to human applications. The research team has funding from JDRF to study whether an immune barrier they created will allow the cells to be accepted in genetically different mice models. If successful, the trials could move to larger animals.

"We broke up our strategy into two steps," said Garcia, a member of Georgia Tech's Petit Institute for Bioengineering and Bioscience. "We have shown that when delivered in the material we engineered, the islets will survive and graft. Now we must address immune acceptance issues."

Most people with Type 1 diabetes currently manage their blood glucose levels with multiple daily insulin injections or by using an insulin pump. But insulin therapy has limitations. It requires careful measurement of blood glucose levels, accurate dosage calculations and regular compliance to be effective.

This work was also funded by the Regenerative Engineering and Medicine Center at Georgia Tech and Emory, and the Atlanta Clinical and Translation Science Institute under PHS grant UL RR025008 from the Clinical and Translational Science Award Program.

The Center for Pediatric Healthcare Technology Innovation at Georgia Tech, the Department of Veterans Affairs Merit Review Program and the National Institutes of Health's National Institute of Diabetes and Digestive and Kidney Diseases (Grant R01 DK076801-01) helped fund the project as well.
