Washington: A new report ranking various nation’s vulnerability to cyberattacks placed India among the countries most vulnerable to cyberattacks.

Data-mining experts from the University of Maryland and Virginia Tech recently co-authored a book that ranked the vulnerability of 44 nations to cyber attacks.

Lead author V S Subrahmanian discussed this research on Wednesday, March 9 at a panel discussion hosted by the Foundation for Defense of Democracies in Washington, DC.

The United States ranked 11th safest while several Scandinavian countries (Denmark, Norway, and Finland) ranked the safest. China, India, Russia, Saudi Arabia and South Korea ranked among the most vulnerable.

Subrahmanian noted that the goal was to characterize how vulnerable different countries were, identify their current cybersecurity policies and determine how those policies might need to change in response to this new information.

The book’s authors conducted a two-year study that analyzed more than 20 billion automatically generated reports, collected from 4 million machines per year worldwide. The researchers based their rankings, in part, on the number of machines attacked in a given country and the number of times each machine was attacked.

Machines using Symantec anti-virus software automatically generated these reports, but only when a machine’s user opted in to provide the data.

Trojans, followed by viruses and worms, posed the principal threats to machines in the United States. However, misleading software (i.e., fake anti-virus programs and disk cleanup utilities) is far more prevalent in the US compared with other nations that have a similar gross domestic product. These results suggest that US efforts to reduce cyber threats should focus on education to recognize and avoid misleading software.

In a foreword to the book, Isaac Ben-Israel, chair of the Israeli Space Agency and former head of that nation’s National Cyber Bureau, wrote “People, even experts, often have gross misconceptions about the relative vulnerability [to cyber attack] of certain countries. The authors of this book succeed in empirically refuting many of those wrong beliefs.”

The book’s findings include economic and educational data gathered by UMD’s Center for Digital International Government, for which Subrahmanian serves as director.

The researchers integrated all of the data to help shape specific policy recommendations for each of the countries studied, including strategic investments in education, research and public-private partnerships. (IANS)

NASA’s TESS Discovers New Worlds Only 5 Months After Its Launch

With four special cameras, TESS uses a detection method called transit photometry.

A planet-hunting orbital telescope designed to detect worlds beyond our solar system discovered two distant planets this week five months after its launch from Cape Canaveral, Florida, officials said on Thursday.

NASA’s Transiting Exoplanet Survey Satellite, better known as TESS, made an early discovery of “super-Earth” and “hot Earth” planets in solar systems at least 49 light-years away, marking the satellite’s first discovery since its April launch.

TESS is on a two-year, $337 million mission to expand astronomers’ known catalog of so-called exoplanets, worlds circling distant stars.

While the two planets are too hot to support life, TESS Deputy Science Director Sara Seager expects many more such discoveries.

“We will have to wait and see what else TESS discovers,” Seager told Reuters. “We do know that planets are out there, littering the night sky, just waiting to be found.”

TESS is designed to build on the work of its predecessor, the Kepler space telescope, which discovered the bulk of some 3,700 exoplanets documented during the past 20 years and is running out of fuel.

NASA expects to pinpoint thousands more previously unknown worlds, perhaps hundreds of them Earth-sized or “super Earth” sized — no larger than twice as big as our home planet.

Those are believed the most likely to feature rocky surfaces or oceans and are thus considered the best candidates for life to evolve. Scientists have said they hope TESS will ultimately help catalog at least 100 more rocky exoplanets for further study in what has become one of astronomy’s newest fields of exploration.

MIT researchers on Wednesday announced the discovery of Pi Mensae c, a “super-earth” planet 60 light-years away orbiting its sun every 6.3 days. The discovery of LHS 3844 b, a “hot-earth” planet 49 light-years away that orbits its sun every 11 hours, was announced on Thursday.

Pi Mensae c could have a solid surface or be a waterworld as the composition of such planets is a mixed bag, Martin Spill, NASA’s program scientist for TESS, said in a phone interview.

The two newest planets, which still need to be reviewed by other researchers, offer the chance for follow-up study, officials said.

“That, of course, is TESS’ entire purpose — to find those planets around those brightest nearby stars to do this really detailed characterization,” Spill said.

With four special cameras, TESS uses a detection method called transit photometry, which looks for periodic dips in the visible light of stars caused by planets passing, or transiting, in front of them. (VOA)
