New tool to check spread of fake news developed

December 23, 2016

Washington, Dec 22: Scientists have launched a powerful new tool in the fight against the spread of fake news through social networking sites.

fnewsThe tool, called Hoaxy, visualises how claims made in fake news spread online.

"In the past year, the influence of fake news in the US has grown from a niche concern to a phenomenon with the power to sway public opinion," said Filippo Menczer, a professor at Indiana University (IU) in the US.

"We've now even seen examples of fake news inspiring real-life danger, such as the gunman who fired shots in a Washington, DC pizza parlour in response to false claims of child trafficking," said Menczer.

Users can enter a claim into the service's website and see results that show both incidents of the claim in the media and attempts to fact-check it by independent organisations.

These results can then be selected to generate a visualization of how the articles are shared across social media.

The site's search results display headlines that appeared on sites known to publish inaccurate, unverified or satirical claims based upon lists compiled and published by reputable news and fact-checking organisations.

A search of the terms "cancer" and "cannabis," for example, turns up multiple claims that cannabis has been found to cure cancer, a statement whose origins have been roundly debunked by the reputable fact-checking website.

A search of social shares of articles that make the claim, however, shows a clear rise in people sharing the story, with under 10 claims in July rising to hundreds by December.

Hoaxy's visualisations illustrate both temporal trends and diffusion networks as they relate to online claims and fact-checks, said Giovanni Luca Ciampaglia, a research scientist at the IU Network Science Institute.

Temporal trends plot the cumulative number of Twitter shares over time. Diffusion networks show how claims spread from person to person.

Twitter is currently the only social network tracked by Hoaxy, and only publicly posted tweets appear in the visualisations.

"Not all claims you can visualize on Hoaxy are false, nor are we saying that the fact-checkers are 100 per cent correct all of the time," said Menczer.

"Hoaxy is a tool to observe how unverified stories and the fact-checking of those stories spread on public social media. It's up to users to evaluate the evidence about a claim and its rebuttal," he said.

New Delhi, Feb 26: With the government pushing for the disinvestment of Air India, industrial conglomerate Adani Group may emerge as one of the bidders for the debt-laden national carrier, sources said.

According to highly placed sources, the Group has held internal rounds of deliberations on whether or not to submit an Expression of Interest (EoI) and the discussions are still in the preliminary stage.

If the company actually submits an EoI, it would be a major move towards further diversification of the company which has business interests across sectors right from edible oil, food to mining and minerals. 

It also entered into airport operations and maintenance business and won bids for privatisation of six airports, Ahmedabad, Lucknow, Jaipur, Guwahati, Thiruvananthapuram and Mangaluru in 2019. 

On being contacted by IANS, the company did not comment on the matter.

Air India is one of the most important divestment proposals for the current fiscal to reach the huge Rs 2.1 lakh crore target.

The government in January restarted the divestment process of the airline and invited bids for selling 100 per cent of its equity in the state-owned airline, including Air India's 100 per cent shareholding in AI Express Ltd. and 50 per cent in Air India SATS Airport Services Private Ltd.

After its unsuccessful bid to sell Air India in 2018, the government this time has decided to offload its entire stake. In 2018, it had offered to sell its 76 per cent stake in the airline.

Of the total debt of Rs 60,074 crore as of March 31, 2019, the buyer would be required to absorb Rs 23,286 crore.

Air India, along with its subsidiary Air India Express, has a total operational fleet of 146 aeroplanes.

Further, the disinvestment department has extended the last date for submission of written queries on the Performance Information Memorandum and Share Purchase Agreement to March 6.

The last date for submission of written queries on PIM and SPA was originally set for February 11, following which the Department of Investment and Public Asset Management (DIPAM) on February 21 issued 20 clarifications on the queries raised and expected.

Any delay in the tentatively rolled out timeline would also delay DIPAM's plan to identify the pre-qualified bidders by March 31 and the financial bids invitation as well. It is expected to take more than two months after the selection of the pre-qualified bidders to complete Air India's sale.

San Francisco, Mar 18: Facebook said a bug in its anti-spam system temporarily blocked the publication of links to news stories about the coronavirus. Guy Rosen, Facebook's vice president of integrity, said on Twitter Tuesday that the company was working on a fix for the problem.

Users complained that links to news stories about school closings and other information related to the virus outbreak were blocked by the company's automated system.

Later on Tuesday, Rosen tweeted that Facebook had restored all the incorrectly deleted posts, which also covered topics beyond the coronavirus.

Rosen said the problems were unrelated to any changes in Facebook's content-moderator workforce. The company reportedly sent its human moderators home this week because of the coronavirus outbreak.

A representative for Facebook did not immediately respond to questions on the status of Facebook's content moderators, many of whom do not work directly for the company and are not always able to work from home.

New Delhi, Jul 18: India's national cybersecurity agency CERT-in, has warned people of credit card skimming spreading across the world through e-commerce platforms.

Attackers are typically targeting e-commerce sites because of their wide presence, popularity and the environment LAMP (Linux, Apache, MySQL, and PHP), the Computer Emergency Response Team (CERT-In) said in a notice on Thursday.

Recently, attackers targeted sites which were hosted on Microsoft's IIS server running with the ASP.NET web application framework, it said.

Some of the sites affected by the attack were found to be running ASP.NET version 4.0.30319, which is no longer officially supported by Microsoft and may contain multiple vulnerabilities, CERT-In said.

The notice also included a list of best practices for website developers including the use of the latest version of ASP.NET web framework, IIS web server and database server.

The advisory is based on research by Malwarebytes which found that this skimming campaign likely began sometime in April this year.

Credit card skimming has become a popular activity for cybercriminals over the past few years, and the increase in online shopping during the pandemic means additional business for them, too, Malwarebytes said in a blog post, adding that attackers do not need to limit themselves to the most popular e-commerce platforms.

Researchers from global cybersecurity and anti-virus brand Kaspersky had warned in December last year that more cybercriminal groups will target online payment processing systems in 2020. 

It said that over the past couple of years, so-called JS-skimming (the method of stealing of payment card data from online stores), has gained immense popularity among attackers. 

Kaspersky researchers in their report said they are currently aware of at least 10 different actors involved in these type of attacks.

Their number will continue to grow during the next year, the report said, adding that the most dangerous attacks will be on companies that provide services such as e-commerce as-a-service, which will lead to the compromise of thousands of companies.
