Bombs and weapons recovered in Thalassery

New Delhi, May 6: The government on Wednesday said no data or security breach has been identified in Aarogya Setu after an ethical hacker raised concerns about a potential security issue in the app.

The app is the government's mobile application for contact tracing and disseminating medical advisories to users in order to contain the spread of coronavirus.

On Tuesday, a French hacker and cyber security expert Elliot Alderson had claimed that "a security issue has been found" in the app and that "privacy of 90 million Indians is at stake".

Dismissing the claims, the government said "no personal information of any user has been proven to be at risk by this ethical hacker".

"We are continuously testing and upgrading our systems. Team Aarogya Setu assures everyone that no data or security breach has been identified," the government said through the app’s Twitter handle.

The tweet gave point-by-point clarification on the red flags raised by the hacker.

"We discussed with the hacker and were made aware of the following... the app fetches user location on a few occasions," it said, but added that this was by design and is clearly detailed in the privacy policy.

The app fetches users’ location and stores on the server in a secure, encrypted, anonymised manner - at the time of registration, at the time of self assessment, when users submit their contact tracing data voluntary through the app or when it fetches the contact tracing data of users after they have turned COVID-19 positive, it said.

On another issue that users can get COVID-19 stats displayed on the home screen by changing the radius and latitude-longitude using a script, Aarogya Setu said that all this information is already public for all locations and hence does not compromise on any personal or sensitive data.

"We thank the ethical hacker on engaging with us. We encourage any users who identify a vulnerability to inform us immediately...," it said.

Responding to Aarogya Setu's clarification, Alderson tweeted, "I will come back to you tomorrow".

New Delhi, May 15: A group of doctors from the AIIMS, Raipur has recommended restrictions on the use of mobile phones in healthcare institutions amid the COVID-19 pandemic, warning that such devices can be a potential carrier of the virus and lead to infection among healthcare workers.

In a commentary published in the BMJ Global Health journal, the doctors stated that mobile phone surfaces are a peculiar 'high-risk' surface, which can directly come in contact with the face or mouth, even if hands are properly washed and one study indicates that some healthcare workers use phones every 15 minutes to two hours.

Though there have been many significant guidelines from various health organisations like the WHO and CDC focusing on prevention and control of disease, the commentary highlighted "there is no mention of or focus on mobile phones in these guidelines, including the WHO infection control and prevention guidelines, which recommends the use of handwashing".

In healthcare facilities, phones are used to communicate with other health care workers, look up recent medical guidelines, research drug interactions, understand adverse events and side effects, conduct telemedicine appointments and track patients among others, stated the document.

The document has been authored by Dr Vineet Kumar Pathak, Dr Sunil Kumar Panigrahi, Dr M Mohan Kumar, Dr Utsav Raj and Dr Karpaga Priya P from the Department of Community and Family Medicine.

"In their tendency to come in direct contact with the face, nose or eyes in healthcare settings, mobile phones are perhaps second only to masks, caps or goggles," the authors said.

"However, they are neither disposable nor washable like these other three, thus warranting disinfection. Mobile phones can effectively negate hand hygiene... There is growing evidence that mobile phones are a potential vector for pathogenic organisms," they said.

It is the need of the hour to address proper hygienic use of mobile phones in healthcare settings. In a study in India, almost 100 per cent of health workers of a tertiary care hospital used mobile phones in the hospital, but only 10 per cent of them had at any time wiped their mobile phones clean, the commentary published on April 22 said.

"The safest thing to do is to consider your phone as an extension of your hand, so remember you are transferring whatever is on your phone to your hand," Dr Pathak said.

Amidst the ongoing pandemic, two biggest mobile phone companies have uploaded their user support guidelines, saying that 70 pc isopropyl alcohol or Clorox Disinfecting Wipes can be used to gently wipe the exterior surface of phones in switched-off mode.

However, in doing so, the use of bleach or entry of moisture through any of the openings must be avoided, and any harsh chemical may damage the oleophobic screen, leading to damage in the touch screen sensitivity of the phone, the article stated.

Mobile phones are one of the most highly touched surfaces according to the Centers for Disease Control and Prevention (CDC), along with counters, tabletops, doorknobs, bathroom fixtures, toilets, keyboards, tablets and bedside tables.

The doctors recommended restriction on mobile phone usage in healthcare settings like hospital wards, ICUs and operation theatres, while advocating the use of headphones to prevent contact with the face while talking.

There should be no sharing of mobile phones, headphones or headsets of any kind. In addition, where available, the use of interdepartmental intercom facility may be promoted.

"Although hand hygiene and mobile phone use by a person are not mutually exclusive, it is high time to acknowledge the potential role of mobile phones in disease transmission cascade and to take evidence-based appropriate actions. This is especially important, given the ongoing COVID-19 pandemic," the authors said.

They said it is necessary for government agencies and the WHO to generate public awareness and to formulate suitable information, education and communication material on mobile phone hygiene, especially in healthcare settings.

AIIMS, New Delhi, Resident Doctors' Association (RDA) General Secretary, Dr Srinivas Rajkumar T said even outside health care settings, people should pay special attention to the usage of mobile phones as they carry them to all places.

"Phone and computer peripherals like keyboard, mouse, etc. should be covered with transparent plastic covers which can be cleaned without interfering with their function. Cleaning hands by soap or alcohol-based hand sanitizer before and after contact with phone and between contact with other surfaces can decrease the risk of potential transmission.

"Using a handsfree headset, dedicated operator/assistant per ward handling the communication via common line in hospitals while on duty can enable communication without compromising safety," Dr Srinivas said.

New Delhi, Mar 2: As communal violence spiked in north-east Delhi earlier this week, Hindu, Muslim and Sikh residents of a colony came together and stood guard against frenzied mobs which ran riot in nearby areas vandalising homes, shops and torching cars.

They have not let their guard down even as the situation is limping back to normalcy following four days of violence that has claimed at least 42 lives and left over 200 injured.

The B-Block colony in Yamuna Vihar has a Hindu-dominated Bahjanpura on one side and Muslim populated Ghonda on the other.

People from all faiths in the locality sit outside their homes at night and deal with any suspected outsider, Arib, a dentist in his 30s, said.

"It is the sloganeering by mobs that causes panic in the dead of night. Such slogans are from both sides and we hear groups of people moving forward towards our area.

"This is where we let the Muslim locals deal with Muslim groups and Hindu residents deal with Hindu groups coming from outside," he said.

Businessmen, doctors and people working at government offices stuck together as violence reached its crest on Monday and Tuesday, and have been guarding the locality round the clock.

Earlier, the locals had claimed inadequate police deployment in the area, but were satisfied as patrolling by security personnel increased in the last two days.

Charanjeet Singh, a Sikh who owns a transport firm, said residents have ensured that not too many people gather to guard the colony at night. It has been decided not use sticks or rods, an idea which seems to have worked in maintaining peace, he said.

"I was 10 years old when we came to this locality from Uttar Pradesh's Meerut in 1982. There were riots in 1984 and tension in 2002, but even then our area remained peaceful. We have always been united and that is the way we have helped each other," Singh, who is now in his 50s, told PTI.

Faisal, a businessman in his 30s, said after two days of major violence, there was palpable tension in the area. "Nobody could sleep in the neighbourhood even on Wednesday and Thursday when the situation was brought under control," he said.

Faisal said around 4 am on Wednesday, three to four miscreants had torched a car, but were chased away by vigilant residents. They raised an alarm and others gathered, saving other vehicles parked nearby from being damaged, he added.

On the idea of not keeping sticks while guarding B-Block, Singh said, "Violence begets violence, crowd begets crowd. We thought if somebody would see sticks or rods in our hands from a distance and large crowds standing guard, it is likely they would want to come prepared. This could fuel violence."

"Now, if there is some young man returning late in the night, we identify if he belongs to our area. If not, we normally inform him about the situation and guide him to his destination, if required," he added.

Seventy-year-old V K Sharma said people in his colony never had any trouble with each other, as he blamed "outside elements" for the violence in north-east Delhi.

"Some people have some problem with symbols. If they find a particular religion's symbol on a shop, home or a car, they vandalise it.

"This is on both sides, Hindus as well as Muslims. But not all people in all religion are like that. There are good people who outnumber these handful people involved in violence," he said.

The violence happened for two days but it would take months for fear to subside, Sharma said, as he took out his two granddaughters, aged nine and two, out for ice cream.

"I cannot reduce the tension outside my home, but at least I can make these kids feel good by reducing their craving for ice cream,” he added.

Colony resident Shiv Kumar, a property consultant, and Wasim, a government official, said they too were members of this voluntary guards' team of the colony which stays up at night to fend off miscreants.
