Washington, Apr 23: Air pollution over northern India has plummeted to a 20-year-low for this time of the year, according to satellite data published by US space agency National Aeronautics and Space Administration (NASA).
The US space agency's satellite sensors observed aerosol levels at a 20-year low post the countrywide lockdown, implemented to slow the spread of the novel coronavirus.

"We knew we would see changes in atmospheric composition in many places during the lockdown," said Pawan Gupta, a Universities Space Research Association (USRA) scientist at NASA''s Marshall Space Flight Center. "But I have never seen aerosol values so low in the Indo-Gangetic Plain at this time of year," added Mr Gupta.

Acting Assistant Secretary of State for South and Central Asia Alice G Wells tweeted, "These images from NASA were taken each spring starting in 2016 and show a 20-year low in airborne particle levels over India. When India and the world are ready to work and travel again, let's not forget that collaborative action can result in cleaner air."

The data published with maps show aerosol optical depth (AOD) in 2020 compared to the average for 2016-2019. Aerosol optical depth is a measure of how light is absorbed or reflected by airborne particles as it travels through the atmosphere.

If aerosols are concentrated near the surface, an optical depth of 1 or above indicates very hazy conditions. An optical depth, or thickness, of less than 0.1 over the entire atmospheric vertical column is considered "clean." The data were retrieved by the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA's Terra satellite.

In the first few days of the lockdown, it was difficult to observe a change in the pollution signature. "We saw an aerosol decrease in the first week of the shutdown, but that was due to a combination of rain and the lockdown," said Mr Gupta.

Around March 27, heavy rain poured over vast areas of northern India and helped clear the air of aerosols. Aerosol concentrations usually increase again after such heavy precipitation.

"After the rainfall, I was really impressed that aerosol levels did not go up and return to normal. We saw a gradual decrease and things have been staying at the level we might expect without anthropogenic emissions," Mr Gupta said.

On March 25, the Indian government placed its 1.3 billion citizens under a strict lockdown to reduce the spread of COVID-19. The countrywide mandate decreased activity at factories and severely reduced car, bus, truck and airplane traffic. Every year, aerosols from anthropogenic (human-made) sources contribute to unhealthy levels of air pollution in many Indian cities.

Aerosols are tiny solid and liquid particles suspended in the air that reduce visibility and can damage the human lungs and heart.

In southern India though, the story is a little hazier. Satellite data show aerosol levels have not yet decreased to the same extent. In fact, levels seem to be slightly higher than in the past four years. The reasons are unclear but could be related to recent weather patterns, agricultural fires, winds or other factors.

"This a model scientific experiment," Robert Levy, program leader for NASA's MODIS aerosol products, said about the lockdown and its effects on pollution.

"We have a unique opportunity to learn how the atmosphere reacts to sharp and sudden reductions in emissions from certain sectors. This can help us separate how natural and human sources of aerosols affect the atmosphere," Mr Levy added.

Bengaluru, Apr 30: Shares of Glenmark Pharmaceuticals Ltd rose almost 9% on Thursday after the Indian drugmaker got an approval to conduct clinical trials with antiviral drug favipiravir, seen as a potential treatment for COVID-19.

Favipiravir, manufactured under the brand name Avigan by a unit of Japan's Fujifilm Holdings Corp and approved for use as an anti-flu drug in the Asian island country in 2014, has been effective, with no obvious side-effects, in helping coronavirus patients recover, a Chinese official told reporters at a news conference last month.

"After having successfully developed the API and the formulations ... Glenmark is all geared to immediately begin clinical trials on favipiravir on COVID-19 patients in India," Sushrut Kulkarni, executive vice-president for Global R&D, Glenmark Pharmaceuticals, said in a statement. 

The Drug Controller General of India, the country's drug regulator, did not immediately respond to Reuters request for comment.

On Wednesday, another Indian pharmaceutical company, Strides Pharma Science Ltd, said it had developed and commercialized favipiravir antiviral tablets, and had applied to Indian drug authorities to start trials.

Shares of Mumbai-based Glenmark Pharmaceuticals, which rose as much as 8.9% to 359 rupees ($4.78), was trading up 5.9%, as of 0407 GMT.

Jun 27: Alittle-known Indian IT firm offered its hacking services to help clients spy on more than 10,000 email accounts over a period of seven years.

New Delhi-based BellTroX InfoTech Services targeted government officials in Europe, gambling tycoons in the Bahamas, and well-known investors in the United States including private equity giant KKR and short seller Muddy Waters, according to three former employees, outside researchers, and a trail of online evidence.

Aspects of BellTroX's hacking spree aimed at American targets are currently under investigation by U.S. law enforcement, five people familiar with the matter told Reuters. The U.S. Department of Justice declined to comment.

Reuters does not know the identity of BellTroX's clients. In a telephone interview, the company's owner, Sumit Gupta, declined to disclose who had hired him and denied any wrongdoing.

Muddy Waters founder Carson Block said he was "disappointed, but not surprised, to learn that we were likely targeted for hacking by a client of BellTroX." KKR declined to comment.

Researchers at internet watchdog group Citizen Lab, who spent more than two years mapping out the infrastructure used by the hackers, released a report that BellTroX employees were behind the espionage campaign.

"This is one of the largest spy-for-hire operations ever exposed," said Citizen Lab researcher John Scott-Railton.

Although they receive a fraction of the attention devoted to state-sponsored espionage groups or headline-grabbing heists, "cyber mercenary" services are widely used, he said. "Our investigation found that no sector is immune."

A cache of data reviewed by Reuters provides insight into the operation, detailing tens of thousands of malicious messages designed to trick victims into giving up their passwords that were sent by BellTroX between 2013 and 2020. The data was supplied on condition of anonymity by online service providers used by the hackers after Reuters alerted the firms to unusual patterns of activity on their platforms.

The data is effectively a digital hit list showing who was targeted and when. Reuters validated the data by checking it against emails received by the targets.

On the list: judges in South Africa, politicians in Mexico, lawyers in France and environmental groups in the United States. These dozens of people, among the thousands targeted by BellTroX, did not respond to messages or declined comment.

Reuters was not able to establish how many of the hacking attempts were successful.

BellTroX's Gupta was charged in a 2015 hacking case in which two U.S. private investigators admitted to paying him to hack the accounts of marketing executives. Gupta was declared a fugitive in 2017, although the U.S. Justice Department declined to comment on the current status of the case or whether an extradition request had been issued.

Speaking by phone from his home in New Delhi, Gupta denied hacking and said he had never been contacted by law enforcement. He said he had only ever helped private investigators download messages from email inboxes after they provided him with login details.

"I didn't help them access anything, I just helped them with downloading the mails and they provided me all the details," he told Reuters. "I am not aware how they got these details but I was just helping them with the technical support."

Reuters could not determine why the private investigators might need Gupta to download emails. Gupta did not return follow-up messages. Spokesmen for Delhi police and India's foreign ministry did not respond to requests for comment.

HOROSCOPES AND PORNOGRAPHY

Operating from a small room above a shuttered tea stall in a west-Delhi retail complex, BellTroX bombarded its targets with tens of thousands of malicious emails, according to the data reviewed by Reuters. Some messages would imitate colleagues or relatives; others posed as Facebook login requests or graphic notifications to unsubscribe from pornography websites.

Fahmi Quadir's New York-based short selling firm Safkhet Capital was among 17 investment companies targeted by BellTroX between 2017 and 2019. She said she noticed a surge in suspicious emails in early 2018, shortly after she launched her fund.

Initially "it didn't seem necessarily malicious," Quadir said. "It was just horoscopes; then it escalated to pornography."

Eventually the hackers upped their game, sending her credible-sounding messages that looked like they came from her coworkers, other short sellers or members of her family. "They were even trying to emulate my sister," Quadir said, adding that she believes the attacks were unsuccessful.

U.S. advocacy groups were also repeatedly targeted. Among them were digital rights organizations Free Press and Fight for the Future, both of whom have lobbied for net neutrality. The groups said a small number of employee accounts were compromised, but the wider organizations' networks were untouched. The spying on those groups was detailed in a report by the Electronic Frontier Foundation in 2017, but has not been publicly tied to BellTroX until now.

Timothy Karr, a director at Free Press, said his organization "sees an uptick in breach attempts whenever we're engaged in heated and high-profile public policy debates." Evan Greer, deputy director of Fight for the Future, said: "When corporations and politicians can hire digital mercenaries to target civil society advocates, it undermines our democratic process."

While Reuters was not able to establish who hired BellTroX to carry out the hacking, two former employees said the company and others like it were usually contracted by private investigators on behalf of business rivals or political opponents.

Bart Santos of San Diego-based Bulldog Investigations was one of a dozen private detectives in the United States and Europe who told Reuters they had received unsolicited advertisements for hacking services out of India - including one from a person who described himself as a former BellTroX employee. The pitch offered to carry out "data penetration" and "email penetration."

Santos said he ignored those overtures, but could understand why some people didn't. "The Indian guys have a reputation for customer service," he said.
