MWC 2020 cancelled as Barcelona bows to coronavirus concerns



MWC won’t be taking place this year after all (GSMA)

The biggest tech event in Europe has been cancelled this year due to the outbreak of coronavirus.

Mobile World Congress (MWC) usually takes place every February in Barcelona and brings together over 100,000 attendees to showcase all aspects of mobile technology.

However, the spread of coronavirus has caused many companies – including the likes of Sony and Amazon – to pull out of the show. Now the organisation in charge of the show has decided to cancel it altogether.

‘With due regard to the safe and healthy environment in Barcelona and the host country today, the GSMA has cancelled MWC Barcelona 2020 because the global concern regarding the coronavirus outbreak, travel concern and other circumstances, make it impossible for the GSMA to hold the event,’ explained John Hoffman, CEO of GSMA Limited.

The announcement followed a crisis meeting of the GSMA board, after its hand was forced by the pullout of anchor European members including Deutsche Telekom, Vodafone, BT and Nokia.

Barcelona’s mayor Ada Colau said earlier she wanted to send a ‘message of calm’, insisting the city was ready to host the event, while Spanish health officials reiterated that there was no reason to call off MWC.

The World Health Organisation, a UN agency leading the coronavirus crisis response, had also called in vain for calm.

‘There is no evidence at present to suggest that there is community spread outside China, so WHO is not currently requesting that large gatherings are cancelled,’ WHO spokesman Tarik Jasarevic told Reuters in Geneva.

That failed, however, to alleviate concerns among major exhibitors that the precautions would be insufficient to halt the virus that has spread beyond China’s borders to two dozen countries.

‘To bring people together and connect them: That is what Telekom stands for. This is also what the Mobile World Congress, the ‘class reunion’ of our industry, stands for,’ Deutsche Telekom CEO Tim Hoettges posted on LinkedIn.

He added, however, that large gatherings of people with many international guests posed a particular risk: ‘To take this risk would be irresponsible.’

The Chinese contingent at MWC has numbered 5,000-6,000 in recent years, making the event particularly vulnerable given the outbreak of the virus that has killed more than 1,100 people on the Chinese mainland.

In its statement, the GSMA said the host cities and partners respected and understood its decision, adding that they would ‘continue to be working in unison’ towards staging next year’s event.

In another security blow, thousands of private Zoom videos can be found online



  • Zoom’s video conferencing software has soared in popularity over the past few weeks as millions of people remain stuck at home on coronavirus quarantine.
  • Zoom’s privacy record leaves much to be desired as the company has faced one controversy after another.
  • Most recently, it was discovered that thousands of private Zoom video chats can be viewed online.
  • Visit BGR’s homepage for more stories.

With millions of people stuck at home because of the coronavirus, Zoom’s video conferencing software has absolutely skyrocketed in popularity over the past few weeks. Just this week, the company said that the number of people using its software on a daily basis jumped from 10 million in December to 200 million in March. That’s an astounding increase and, not surprisingly, shares of Zoom have more than doubled in that same period.

Zoom’s ascension, however, hasn’t been an entirely smooth ride. The company in recent weeks has had to contend with one controversy after another. At first, word surfaced that the Zoom app on iOS was sending analytics data to Facebook, regardless of whether a user had a Facebook account of not. Following that, we learned that email addresses and photos of some Zoom users were leaking out. And of course, there was that pesky issue of strangers “zoombombing” third-party calls.

Zoom, to its credit, has been relatively quick to respond to the above issues. But just as one issue is addressed, another one seems to emerge. To this end, The Washington Post is reporting that thousands of Zoom recordings in the cloud can be accessed and viewed by complete strangers due to the way the files are named.

When you engage in a video call, it’s only natural to assume that your conversation will not ever be viewed by a third-party. As it turns out, that’s a dangerous assumption to make if you’re using Zoom to discuss sensitive and potentially embarrassing personal information.

Videos viewed by The Washington Post included one-on-one therapy sessions; a training orientation for workers doing telehealth calls that included people’s names and phone numbers; small-business meetings that included private company financial statements; and elementary school classes, in which children’s faces, voices and personal details were exposed.

Many of the videos include personally identifiable information and deeply intimate conversations, recorded in people’s homes. Other videos include nudity, such as one in which an aesthetician teaches students how to give a Brazilian wax.

It’s worth noting that Zoom calls are not automatically recorded. Still, the host of a call has the power to unilaterally save video chats to their computer or to Zoom’s own servers.

With the security issues involving Zoom seemingly growing by the day, company founder and CEO Eric S. Yuan explained that many of the issues stem from the fact that the company didn’t anticipate Zoom being used to this extent outside of the enterprise.

“Our platform was built primarily for enterprise customers – large institutions with full IT support,” Yuan said. “However, we did not design the product with the foresight that, in a matter of weeks, every person in the world would suddenly be working, studying, and socializing from home. We now have a much broader set of users who are utilizing our product in a myriad of unexpected ways, presenting us with challenges we did not anticipate when the platform was conceived.”

As to the most recent security issue, the company issued the following statement on the matter:

Zoom notifies participants when a host chooses to record a meeting, and provides a safe and secure way for hosts to store recordings. Zoom meetings are only recorded at the host’s choice either locally on the host’s machine or in the Zoom cloud. Should hosts later choose to upload their meeting recordings anywhere else, we urge them to use extreme caution and be transparent with meeting participants, giving careful consideration to whether the meeting contains sensitive information and to participants’ reasonable expectations.

All this being said, Yuan a few days ago said that Zoom will be implementing a 90-day freeze on new features to allow its engineers some time to address the aforementioned security concerns.

Potential coronavirus vaccine shows hope in mouse study



A researcher at the University of Pittsburgh works on a COVID-19 vaccine candidate (Reuters)

Initial tests in mice of a potential COVID-19 vaccine delivered via a fingertip-sized patch have shown it can induce an immune response against the new coronavirus at levels that might prevent infection, U.S. scientists said on Thursday.

Researchers around the world are working to develop potential treatments or vaccines against the respiratory disease that has killed nearly 47,000 people and infected almost a million in just a few months.

A team at the University of Pittsburgh School of Medicine in the United States said they were able to move quickly in developing a potential COVID-19 vaccine after working on other coronaviruses that cause Severe Acute Respiratory Syndrome (SARS) and Middle East Respiratory Syndrome (MERS).

‘These two viruses, which are closely related to SARS-CoV-2 (the new coronavirus causing the COVID-19 pandemic), teach us that a particular protein, called a spike protein, is important for inducing immunity against the virus,’ said Andrea Gambotto, an associate professor at Pittsburgh.

‘We knew exactly where to fight this new virus.’

When tested in mice, the prototype vaccine – which the researchers have called PittCoVacc – generated what they described as ‘a surge of antibodies’ against the new coronavirus within two weeks.

The Pittsburgh researchers cautioned that because the animals have not been tracked for very long as yet, it is too early to say whether and for how long the immune response against COVID-19 lasts.

But they said that in comparable tests in mice with their MERS experimental vaccine, a sufficient level of antibodies was produced to neutralize the virus for at least a year.

So far, the antibody levels of the SARS-CoV-2 vaccinated animals seem to be following the same trend, they said in peer-reviewed study in the journal EBioMedicine.

The team said they hope to start testing the vaccine candidate on people in clinical trials in the next few months.

The potential vaccine uses a needle patch design, called a microneedle array, to increase its potential potency.

This array is a fingertip-sized patch of 400 tiny needles made out of sugar and the spike protein, Gambotto explained. It is designed to deliver the spike protein pieces into the skin, where the immune reaction is strongest.
