Online users in India are yet to wake up to threat posed by hackers

November 21, 2016

Nov 21: Consumers who were victims of cybercrime within the past year often continued their unsafe behaviour, reveals the India findings from the 2016 Norton Cyber Security Insights Report.

OnlineFor example, while these consumers were equally likely to use the same password for every account, they were over twice as likely to share their password with others, said the annual report that was released on 17 November. Also, 79% of consumers know they must actively protect their information online, but they still share passwords and engage in other risky behaviour.

Also, close to one in five (18%) consumers have at least one unprotected device, leaving their other devices vulnerable to ransomware (malicious software that blocks access to a computer system until money is paid), malicious websites, zero days and phishing attacks.

While quoting various reasons for not protecting their devices, 36% said they don"t do anything “risky” online; 23% believed security measures would slow them down.

Among those surveyed, a vast majority (85%) of Indians have Wi-Fi in their homes. Proving that thinking about cybersecurity doesn"t mean you"re secure, people who experienced cybercrime within the past year were more likely to be concerned about the security of their home Wi-Fi network (79% vs. 70% non-victims), yet less likely to password-protect their home Wi-Fi network than non-victims (28% vs. 10% of non-victims have unprotected networks).

Only 56% of consumers knew how to determine whether the Wi-Fi network they are using is secure; this is of concern especially since 22% of respondents agreed to have used their neighbour"s Wi-Fi network without their permission, the report said. When it comes to public Wi-Fi, one in four (27%) regularly use public Wi-Fi connections available at places like airports and coffee shops.

Experiencing cybercrime is a potential consequence of living in a connected world, the report acknowledges but cautions that consumers are complacent about protecting their personal information online.

As many as 64% of consumers said that over the past five years, it"s become harder to stay safe online, compared to 60% who said the same of the real world.

According to the report, millennials exhibit surprisingly slack online security habits, and are happy to share passwords that compromise their online safety (34%).

This is likely why they remain the most common victims of cybercrime, with 55% having experienced cybercrime in the past year.

Consumers are still willing to click on links from senders they don"t know or open malicious attachments. One in three (33%) cannot detect a phishing attack. Among those surveyed, 65% of Indian consumers don"t believe there are enough connected device users for it to be a worthwhile target for hackers. Yet, 68% believe that just as hackers learnt to benefit from targeting social media and financial accounts, they are on their way to learning how accessing connected home devices can be lucrative.

Indians also rank high in terms of falling prey to ransomware, according to the report. One in three (33%) have either experienced ransomware or know someone who has; 83% of ransomware victims fell prey to it in the past one year alone, indicating a steady rise of this menace.

Leiden, Jul 2: Astronomers have discovered a luminous galaxy caught in the act of reionizing its surrounding gas only 800 million years after the Big Bang.

The research, led by Romain Meyer, PhD student at UCL in London, UK, has been presented at the virtual annual meeting of the European Astronomical Society (EAS).

Studying the first galaxies that formed 13 billion years ago is essential to understanding our cosmic origins. One of the current hot topics in extragalactic astronomy is 'cosmic reionization,' the process in which the intergalactic gas was ionized (atoms stripped of their electrons).

Cosmic reionization is similar to an unsolved murder: We have clear evidence for it, but who did it, how and when? We now have strong evidence that hydrogen reionization was completed about 13 billion years ago, in the first billion years of the universe, with bubbles of ionized gas slowly growing and overlapping.

The objects capable of creating such ionized hydrogen bubbles have however remained mysterious until now: the discovery of a luminous galaxy in which 60-100 percent of ionizing photons escape, is likely responsible for ionizing its local bubble. This suggests the case is closer to being solved.

The two main suspects for cosmic reionization are usually 1) a population of numerous faint galaxies leaking ~10 percent of their energetic photons, and 2) an 'oligarchy' of luminous galaxies with a much larger percentage (>50 percent) of photons escaping each galaxy.

In either case, these first galaxies were very different from those today: galaxies in the local universe are very inefficient leakers, with only <2-3 percent of ionizing photons escaping their host. To understand which galaxies governed cosmic reionization, astronomers must measure the so-called escape fractions of galaxies in the reionization era.

The detection of light from excited hydrogen atoms (the so-called Lyman-alpha line) can be used to infer the fraction of escaping photons. On the one hand, such detections are rare because reionization-era galaxies are surrounded by neutral gas which absorbs that signature hydrogen emission.

On the other hand, if this hydrogen signal is detected it represents a 'smoking gun' for a large ionized bubble, meaning we have caught a galaxy reionizing its surroundings. The size of the bubble and the galaxy's luminosity determines whether it is solely responsible for creating this ionized bubble or if unseen accomplices are necessary.

The discovery of a luminous galaxy 800 million years after the Big Bang supports the scenario where an 'oligarchy' of bright leakers emits most of the ionizing photons.

"It is the first time we can point to an object responsible for creating an ionized bubble, without the need for a contribution from unseen galaxies.

Additional observations with the upcoming James Webb Space Telescope will enable us to study further what is likely one of the best suspects for the unsolved case of cosmic reionization," said Meyer.

Tokyo, Feb 25: Japan's Chitetsu Watanabe, recognized at 112 years as the oldest man in the world, has passed away 11 days after he received the Guinness World Record certificate, his family said on Tuesday.

Watanabe died on Sunday night, Efe news reported.

He received the official certificate on February 12 at a nursing home in Joetsu in Niigata prefecture, where he resided.

Soon after being certified as the oldest man, he began to experience a lack of appetite and respiratory problems, the wife of his eldest son told public broadcaster NHK.

Born on March 5, 1907 in a family of farmers, Watanabe moved at the age of 20 to Taiwan, where he worked at a sugar refinery for 18 years before returning to Japan after the end of World War II.

A fan of calligraphy, custard and ice cream, Watanabe told the Guinness team that the key to his long life was laughter.

He was recognized as the oldest male in the world following the deaths in 2019 of German Gustav Gerneth (in October), aged 114 years, and Japan's Masazo Nonaka (in January), at the age of 113, three months older than the German.

It remains to be seen who will be recognized after the death of Watanabe, the only male on the list drawn up by the Gerontology Research Group of the 30 oldest people in the world.

Japan has among the highest life expectancy in the world and the number of centenarians in the country has crossed 71,000, according to the latest government figures.

Since 2000, the number of centenarians censored has quintupled, raising concern for the economic outlook and future workforce of the country - where the birthrate is on a downward trend.

Out of these, 88 per cent are women.

New Zealand's research institute in Antarctica is scaling back the number of projects planned for the upcoming season, in an effort to keep the continent free of coronavirus, it was reported on Tuesday.

The government agency, Antarctica New Zealand, told the BBC on Tuesday that it was dropping 23 of the 36 research projects.

Only long-term science monitoring, essential operational activity and planned maintenance will go ahead.

The upcoming research season runs from October to March.

"As COVID-19 sweeps the planet, only one continent remains untouched and (we) are focused on keeping it that way," Antarctica New Zealand told the BBC.

The organisation's chief executive Sarah Williamson said the travel limits and a strict managed isolation plan were the key factors for keeping Scott Base - New Zealand's research facility - virus free.

"Antarctica New Zealand is committed to maintaining and enhancing the quality of New Zealand's Antarctic scientific research. However, current circumstances dictate that our ability to support science is extremely limited this season" she said.

Earlier in April, Australia announced that it would scale back its activity in the 2020-21 summer season.

This included decreasing operational capacity and delaying work on some major projects.
