"They had their entire lives ahead of them. Birthdays, graduations, weddings, kids of their own."Those were the words of a teary-eyed President Obama on December 14, 2012, the day 20 children and six adults were shot and killed at Sandy Hook Elementary School in Newtown, Connecticut.It was a day that shook the country to its core. But it was also a day that fundamentally changed the way law enforcement and everyday citizens approach the unimaginable. 462

(CNN) -- Artificially-generated faces of people who don't exist are being used to front fake Facebook accounts in an attempt to trick users and game the company's systems, the social media network said Friday. Experts who reviewed the accounts say it is the first time they have seen fake images like this being used at scale as part of a single social media campaign.The accounts, which were removed by Facebook on Friday, were part of a network that generally posted in support of President Trump and against the Chinese government, experts who reviewed the accounts said. Many of the accounts promoted links to a Facebook page and website called "The BL." Facebook said the accounts were tied to the US-based Epoch Media Group, which owns The Epoch Times newspaper, a paper tied to the Falun Gong movement that is similarly pro-Trump.The publisher of the Epoch Times denied that Epoch and The BL were linked in emails to the fact-checking organization Snopes earlier this year.In a statement released after this story initially published on Friday, Epoch Times publisher Stephen Gregory said, "The Epoch Times and The BL media companies are unaffiliated. The BL was founded by a former employee, and employs some of our former employees. However, that some of our former employees work for BL is not evidence of any connection between the two organizations."The BL is a publication of Epoch Times Vietnam. As can be seen in archived pages of The Epoch Times website, Epoch Times Vietnam was no longer listed as part of Epoch Media Group in October 2018."In response, a Facebook spokesperson told CNN Business that executives at The BL were active administrators on Epoch Media Group Pages as recently as Friday morning.The dystopian revelation of the use of artificially-generated images in this way points to an increasingly complicated online information landscape as America enters a presidential election year. Silicon Valley and the US intelligence community are still struggling with the fallout from widespread online interference in the 2016 presidential election.The Facebook accounts used profile pictures that appeared to show real people smiling and looking directly into a camera. But the people do not and have never existed, according to Facebook and other researchers. The images were created using artificial intelligence technology. The same basic methods are used to produce deepfake videos — fake videos that the US intelligence community has warned could be used as part of a foreign disinformation campaign targeting Americans.Other fake accounts that were part of the same network used stolen pictures of real people, according to the social media investigations company Graphika and the thinktank the Atlantic Council. Facebook provided information to Graphika and the Atlantic Council for analysis in advance of Friday's announcement.The accounts were used to run dozens of pro-Trump Facebook groups with names like "America Needs President Trump," and "WE STAND WITH TRUMP & PENCE!," according to Graphika and the Atlantic Council.The fact-checking organizations Snopes and Lead Stories had reported in recent weeks and months about the use of artificial images on Facebook that were part of this network of accounts. Snopes published a story last week criticizing Facebook's apparent inaction on the issue. Facebook said Friday it had "benefited from open source reporting" in the takedown but said that its own systems that monitor for coordinated and inauthentic behavior had proactively identified many of the accounts.In a joint report on their findings, Graphika and the Atlantic Council outlined how they were able to determine which of the profile photos had been generated using artificial intelligence. "This technology is rapidly evolving toward generating more believable pictures, but a few indicators still give these profile pictures away," they said.Images generated using artificial intelligence, specifically by a machine-learning method known as a GAN, or generative adversarial network, are "notorious for struggling with features that should be symmetrical on the human face, such as glasses or earrings, and with background details. Profile pictures from the network showed telltales of all three."GANs consist of two neural networks — which are algorithms modeled on the neurons in a brain — facing off against each other to produce real-looking images. One of the neural networks generates images (of, say, a woman's face), while the other tries to determine whether that image is a fake or a real face.While experts were able to spot these telltale signs on close inspection, it is likely the regular Facebook user would not.Over the past year, a number of websites have emerged online that create fake faces using artificial intelligence.Researchers from Graphika and the Atlantic Council could not conclusively determine if the people behind the fake accounts had used artificial pictures from these public sites or had generated their own.In their report released Friday, Graphika and the Atlantic Council said, "The ease with which the operation managed to generate so many synthetic pictures, in order to give its fake accounts (mostly) convincing faces, is a concern. Further research is needed to find ways to identify AI-generated profile pictures reliably and at scale, so that platforms and researchers can automate their detection."Connection to Epoch Media GroupIn all, Facebook said Friday, it had removed a network of 610 Facebook accounts, 89 pages, 90 groups, and 72 Instagram accounts. About 55 million accounts followed one or more of the pages, and the vast majority of followers were outside the United States, Facebook said. Facebook did not say if all of all these followers were real — some of them may themselves have been fake accounts.The network of pages removed on Friday had spent almost million on Facebook ads, according to Facebook.Facebook's investigation primarily focused on "The BL" (The Beauty of Life) — a set of Facebook pages and a website that says its goal is to "present to the world the most beautiful aspects of life."The pages often shared pro-Trump and anti-China content.On its website, The BL outlined the dangers of "inaccurate and degenerate information" that it said "can be easily channeled toward vulnerable or uninformed people."The purpose of the fake accounts, including those using fake faces, appears to have been to promote links to The BL's website and Facebook pages, Ben Nimmo, director of investigations at Graphika told CNN Business on Friday.Facebook said the fake accounts were tied to the US-based Epoch Media Group and "individuals in Vietnam working on its behalf." The company did not outline precisely how it made the connection, but in recent years Facebook has hired a team of investigators to find fake accounts on the platform.The Epoch Times newspaper is part of the Epoch Media Group. The newspaper has almost 6 million followers on Facebook. Nathaniel Gleicher, Facebook's head of security policy, told CNN Business Thursday that Facebook was not suspending the newspaper's account but investigations into Epoch's behavior on Facebook were ongoing.Snopes reported earlier this month that the publisher of the Epoch Times denied that The BL and Epoch were linked.In August, Facebook banned ads from The Epoch Times after an NBC News investigation detailed how the newspaper was secretly running pro-Trump Facebook ads under alternate accounts. The Epoch Times' publisher said in a statement to NBC News, "The Epoch Times advertisements are print-subscription advertisements describing our paper's reporting — a popular practice of many publishers — and every one of these ads was approved by Facebook before publishing."A Facebook spokesperson said the company shared its findings with Twitter and Google, which owns YouTube.A Twitter spokesperson confirmed in a statement Friday, "today we identified and suspended approximately 700 accounts originating from Vietnam for violating our rules around platform manipulation — specifically fake accounts and spam.""Investigations are still ongoing, but our initial findings have not identified links between these accounts and state-sponsored actors," the spokesperson added.Google did not immediately respond to CNN Business' request for comment. 8341

"Neither snow nor rain nor heat nor gloom of night stays these couriers from the swift completion of their appointed rounds."While it isn’t the official U.S. Postal Service motto, it’s something mailwoman Amy Bezerra has kept to for the past 25 years. And now, we can add COVID-19 to that list of things that postal workers press through.Bezerra is one of almost half a million mail carriers for the USPS, and for the last eight of those years, she’s had the same route just north of Denver, Colorado."My max is usually six years and then I’m like, 'Eh, it’s time to move on and learn a different area.' Which is really hard, because you get close to your customers," said Bezerra.But because of COVID-19, the part of her job she loves the most has now changed."My customers, being outside, being able to involve yourself with other people, giving customer service to a wide variety of people," said Bezerra. "I don’t see near as many people. Your customers, if they do come out, it’s very rare anymore."People are ordering things now more than ever."A lot of people are not going out to stores purchasing. They’re staying at home and doing it on the computer, which gives us more parcels, which is awesome," said Bezerra.It’s deemed an essential public service, critical to the nation’s infrastructure, and critical to so many lives. However, the carriers also provide a service that many wouldn’t think."You get to know the people, the kids, the pets who should be around in the neighborhood, who shouldn’t, and people’s schedules," said Bezerra.So, a few years ago, when one of her customers didn’t pick up his mail for a few days, she knew something was wrong. She called for help."He had just been real sick and completely dehydrated. But every time he’d get up, he’d pass out and hit his head," said Bezerra.The ER doctors said he wouldn’t have made it 24 hours."I have five more years, and I have really bonded with these people out here. I’ve pretty much promised them, unless the post office takes it away from me, I’m here for five more years with them," said Bezerra.So, snow, rain, heat, gloom of night, nor COVID-19 will stop Bezerra from delivering to her customers. 2188

With more Americans working from home, it appears many companies could stick with telework following the spread of the coronavirus.According to a survey of 150 human resources representatives by The Conference Board, 77% expect a shift toward teleworking one year after the coronavirus spread subsides. Those survey expect more workers to spend at least three days a week from home. While many companies might expand telework, some are reporting a decrease in productivity amid the spread of coronavirus. 32% of professional and office work had a decrease in productivity. That number increased to 44% for companies geared toward industry and manual services. But 21% of professional services and 27% industry and manual services companies saw an increase in productivity. But much of that appears not to be connected to telework, and more a result of decreased staffing and revenue."A shift toward more remote working will have major implications for HR departments," said Robin Erickson, PhD, a report co-author and Principal Researcher at The Conference Board. "Among other changes, they will be able to recruit workers from a broader geographic pool and will need to hire and promote those who can inspire remote teams."To read the full survey, click 1267
