Horrific Achhe Din: India 100th on hunger index; worse than Nepal, Bangladesh

New Delhi, Jun 3: Over 1 lakh scanned copies of Indians' national IDs, including Aadhaar, PAN card and passport, have been put on dark web for sale, cyber intelligence firm Cyble said on Wednesday.

The leaked data seems to have originated from a third party and not from the government system, according to a report by Cyble.

"We came across a non-reputed actor who is currently selling over 1 lakh Indian National IDs on the dark net. With such a low reputation, ideally, we would have skipped this; however, the samples shared by the actor intrigued our interest -- and also the volume. The actor is alleged to have access to over 1 lakh IDs from different places in India," Cyble said.

The personal data leaked by cyber criminals leads to various nefarious activities such as identity thefts, scams, and corporate espionage. Many criminals use the personal details in the IDs to win trust of the people over a phone call for fraudulent activities.

The Cyble researchers acquired around 1,000 IDs from the seller and confirmed that the scanned IDs belong to Indians.

"Preliminary analysis suggests that the data originated from a third party, and no indication or artefact is indicating that it came from a government system. At this point, Cyble researchers are still investigating this further -- we are hoping to share an update soon," Cyble said.

The scanned ID documents indicate that the data may have been leaked from a company's data base in the segment where they have to comply with 'Know Your Customer' (KYC) norms.

"Cyble researchers have also learned about a surge in KYC and banking scams -- leaks such as this are often used by scammers to target individuals, especially elderlies," Cyble said.

The cyber intelligence firm has recommended people to refrain from sharing personal information especially financial information over phone, e-mail or SMS.

"Regularly monitor your financial transaction, if you notice any suspicious transaction, contact your bank immediately," the company said.

In May, Cyble showed two instances where personal data of 7.65 crore Indians have been put on sale in the dark web. In one instance, the seller claimed to have sourced data of 4.75 crore Indians from online directory Truecaller and in other, the seller claimed to have sourced from job websites.

Truecaller, however, had denied the claim of breach in its database.

The current physical distancing guidelines provided by the World Health Organisation (WHO) and by the US Centers for Disease Control and Prevention (CDC) may not be adequate to curb the coronavirus spread, according to a research which says the gas cloud from a cough or sneeze may help virus particles travel up to 8 metres. The research, published in the Journal of the American Medical Association, noted that the the current guidelines issued by the WHO and CDC are based on outdated models from the 1930s of how gas clouds from a cough, sneeze, or exhalation spread.

Study author, MIT associate professor Lydia Bourouiba, warned that droplets of all sizes can travel 23 to 27 feet, or 7-8 metres, carrying the pathogen.

According to Bourouiba, the current guidelines are based on "arbitrary" assumptions of droplet size, "overly simplified", and "may limit the effectiveness of the proposed interventions" against the deadly pandemic.

 She explained that the old guidelines assume droplets to be one of two categories, small or large, taking short-range semi-ballistic trajectories when a person exhales, coughs, or sneezes.

However based on more recent discoveries, the MIT scientist said, sneezes and coughs are made of a puff cloud that carries ambient air, transporting within it clusters of droplets of a wide range of sizes.

Bourouiba warned that this puff cloud, with ambient air entrapped in it, can offer the droplets moisture and warmth that can prevent it from evaporation in the outer environment.

"The locally moist and warm atmosphere within the turbulent gas cloud allows the contained droplets to evade evaporation for much longer than occurs with isolated droplets," she said.

"Under these conditions, the lifetime of a droplet could be considerably extended by a factor of up to 1000, from a fraction of a second to minutes," the researcher explained in the study.

The MIT scientist, who has researched the dynamics of coughs and sneezes for years, added that these droplets settle along the trajectory of a cough or sneeze contaminating surfaces, with their residues staying suspended in the air for hours.

"Even when maximum containment policies were enforced, the rapid international spread of COVID-19 suggests that using arbitrary droplet size cutoffs may not accurately reflect what actually occurs with respiratory emissions, possibly contributing to the ineffectiveness of some procedures used to limit the spread of respiratory disease," Bourouiba wrote in the study

New Delhi, Jun 13: About 56 per cent of children were found to have no access to smartphones which have emerged as essential tools for online learning during the coronavirus-induced lockdown, according to a new study that surveyed 42,831 students at various school levels.

The study ''Scenario amidst COVID 19 - Onground Situations and Possible Solutions'' was conducted by child rights NGO Smile Foundation with an aim of analysing the access to technology.

The findings of the study showed that 43.99 per cent of surveyed children have access to smartphones and another 43.99 per cent of students have access to basic phones while 12.02 per cent do not have access to either smartphones or basic phones.

A total of 56.01 per cent children were found to have no access to smartphones, the study said.

"Concerning television, it was noted that while 68.99 per cent have access to TV, a major chunk of 31.01 per cent does not. Hence suggesting that using smartphone interventions for enhancing learning outcomes is not the only solution," it said.

At the primary level of education (class 1 to 5) 19,576 children were surveyed while at upper primary level (class 6 to 8) 12,277 children were surveyed. At secondary level of education (class 9 to 10) 5,537 children were surveyed and at higher secondary level (class 11 to 12) 3,216 children were surveyed.

The survey based on which the study was conducted used two approaches - over the telephone wherein the NGO reached out to the children whose database it already had -- students enrolled in various education centres of the NGO -- and second was through community mobilization wherein community workers went door to door to get answers.

The survey was conducted in 23 states, including Delhi, Gujarat, Maharashtra, Karnataka, Tamil Nadu, West Bengal, Andhra Pradesh, Telangana, Uttar Pradesh, Haryana, over a period of 12 days from April 16 to April 28.

The lockdown induced by the COVID-19 pandemic in March prompted schools and colleges to move to the virtual world for teaching and learning activities. However, many experts say the digital divide in the country may turn online classes into an operational nightmare.

As per official statistics, there are over 35 crore students in the country. However, it is not clear as to how many of them have access to digital devices and Internet.

Santanu Mishra, co-founder and executive trustee, Smile Foundation, said the findings clearly show that the digital divide is a real challenge, and multiple approaches need to be implemented to cater to all across the nation.

"As an exercise before we start any programme, we do a baseline study to understand the on-ground challenges so that our programmes can bring in real work and real change. With the onset of the pandemic, following indefinite school closures, it is more important than ever to understand the situation and how can we ensure that children are given quality education. Through this, we understand that customized modules need to be built in accordance with the channel of communication," he said.
