ASI stopping Muslims from offering namaz in Taj Mahal, unjustified: Clerics

Several India-based firms are spoofing the World Health Organisation (WHO) by creating fake Gmail accounts and luring business leaders in disguise of informing them of latest COVID-19 announcements and hack their personal and financial information, Google has warned.

These "hack-for-hire" firms, many based in India, have been creating Gmail accounts spoofing the WHO, largely targeting business leaders in financial services, consulting, and healthcare corporations within numerous countries including, the US, Slovenia, Canada, India, Bahrain, Cyprus, and the UK.

"The lures themselves encourage individuals to sign up for direct notifications from the WHO to stay informed of COVID-19 related announcements, and link to attacker-hosted websites that bear a strong resemblance to the official WHO website," security researchers from Google's Threat Analysis Group said on Wednesday.

The sites typically feature fake login pages that prompt potential victims to give up their Google account credentials, and occasionally encourage individuals to give up other personal information, such as their phone numbers.

On any given day, Google's Threat Analysis Group (TAG) said it is tracking more than 270 targeted or government-backed attacker groups from more than 50 countries.

Last month, it sent 1,755 warnings to users whose accounts were targets of government-backed attackers.

"Our team of analysts and security experts is focused on identifying and stopping issues like phishing campaigns, zero-day vulnerabilities and hacking against Google, our products and our users," said the tech giant.

Google continues to see attacks from groups like Charming Kitten on medical and healthcare professionals, including WHO employees.

"We're seeing a resurgence in COVID-related hacking and phishing attempts from numerous commercial and government-backed attackers," said the company.

Government-backed or state-sponsored groups have different goals in carrying out their attacks: Some are looking to collect intelligence or steal intellectual property; others are targeting dissidents or activists, or attempting to engage in coordinated influence operations and disinformation campaigns.

Google said that since March, it has removed more than 1,000 YouTube channels that were part of a large campaign and behaving in a coordinated manner.

"These channels were mostly uploading spammy, non-political content, but a small subset posted primarily Chinese-language political content similar to the findings of a recent Graphika report," said the company.

Several cybersecurity firms have seen a spike in COVID-19 related scams and hacking attempts. Hackers are also creating scam sites similar to COVID-19 relief packages.

Researchers at Check Point Software Technologies revealed in mid-May that they have seen 192,000 coronavirus-related cyber-attacks per week over the past three weeks, a 30 % increase compared to previous weeks.

London, May 20: The current physical distancing guidelines of 6 feet may be insufficient to prevent COVID-19 transmission, according to a study which says a mild cough in low wind speeds can propel saliva droplets by as much as 18 feet.

Researchers, including those from the University of Nicosia in Cyprus, said a good baseline for studying the airborne transmission of viruses, like the one behind the COVID-19 pandemic, is a deeper understanding of how particles travel through the air when people cough.

In the study, published in the journal Physics of Fluids, they said even with a slight breeze of about four kilometres per hour (kph), saliva travels 18 feet in 5 seconds.

"The droplet cloud will affect both adults and children of different heights," said study co-author Dimitris Drikakis from the University of Nicosia.

According to the scientists, shorter adults and children could be at higher risk if they are located within the trajectory of the saliva droplets.

They said saliva is a complex fluid, which travels suspended in a bulk of surrounding air released by a cough, adding that many factors affect how saliva droplets travel in the air.

These factors, the study noted, include the size and number of droplets, how they interact with one another and the surrounding air as they disperse and evaporate, how heat and mass are transferred, and the humidity and temperature of the surrounding air.

In the study, the scientists created a computer simulation to examine the state of every saliva droplet moving through the air in front of a coughing person.

The model considered the effects of humidity, dispersion force, interactions of molecules of saliva and air, and how the droplets change from liquid to vapour and evaporate, along with a grid representing the space in front of a coughing person.

Each grid, the scientists said, holds information about variables like pressure, fluid velocity, temperature, droplet mass, and droplet position.

The study analysed the fates of nearly 1,008 simulated saliva droplets, and solved as many as 3.7 million equations.

"The purpose of the mathematical modelling and simulation is to take into account all the real coupling or interaction mechanisms that may take place between the main bulk fluid flow and the saliva droplets, and between the saliva droplets themselves," explained Talib Dbouk, another co-author of the study.

However, the researchers added that further studies are needed to determine the effect of ground surface temperature on the behaviour of saliva in air.

They also believe that indoor environments, especially ones with air conditioning, may significantly affect the particle movement through air.

This work is important since it concerns safety distance guidelines, and advances the understanding of the transmission of airborne diseases, Drikakis said.

The Retailers Association of India (RAI) has said that ad hoc lockdowns by state governments are impacting the businesses of already-stressed retailers, along with hurting the economic revival of the country.

In a statement, the body of the organised retail industry said that the long road to recovery for the Indian retail industry continues to meet stumbling blocks with numerous restrictions being imposed at the state and local levels.

"Total lockdowns in some places and limited operational hours and days in several others are creating setbacks for retailers as the already stressed retail businesses are getting further interrupted and in turn, dampening consumer sentiment," it said.

According to RAI, although the intentions are that of citizen safety and social distancing, the recent instances of local lockdowns and ad hoc restrictions being imposed in Uttar Pradesh, Maharashtra, Andhra Pradesh and Karnataka are having a distressing impact on retail businesses.

Retailers are already facing huge setbacks in terms of payment of wages and rentals due to very low sales of about 40 per cent as compared to last year, thanks to the extended lockdown, it said.

Contesting the restrictions on operating hours, Sandeep Kataria, CEO, Bata India said: "Restricted shopping time can lead to unnecessary overcrowding of stores, which is unfavourable towards the personal safety of both store staff and customers. Longer operational hours will support recovery for retailers as well as help adhering to social distancing norms."

Arvind Mediratta, MD and CEO, METRO Cash & Carry India said that these lockdowns will create severe inconvenience for all citizens as they also bar operations of food and grocery retail and wholesale stores.

Such hastily-implemented decisions by states undermine investor confidence and would come in the way of making the country "aatmanirbhar" or self-reliant, he said.

Voicing the concerns of retailers, the RAI has submitted representations to various state and local authorities that puts forth recommendations to get businesses and life of consumers on the track to recovery.

It has said that authorities should mandatorily allow essential shops including kiranas, general trade shops, supermarkets, hypermarkets and wholesalers to operate every day of the week until 9 p.m. to cater to the daily needs of the customers.

It has also sought ensuring uniform and regular opening of all categories of retail for full working hours while following stringent hygiene practices and adhering to social distancing norms. This will help avoid overcrowding outside stores as demand will get distributed over all days of the week, it said.

The industry body has also asked the local authorities to open malls in all states. Malls can ensure a safe shopping experience wherein safety measures are taken by both, the mall authorities and the retailers, it said.

Kumar Rajagopalan, CEO, RAI, said: "The need of the hour is concerted efforts by all stakeholders. While retailers are doing their bit by following stringent hygiene practices, the policymakers too need to support to ensure economic revival across the country. Consumption is important for the country and supports the business environment."
