(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

"Ghosting" — The term is usually reserved in online dating when a prospective date doesn't call or text back. Now, it's being used on prospective employers when new hires don't show up for their first day of work.Liz Blondy has roughly 80 employees covering her various K-9 to 5 pet care locations and says she's fallen victim to a trend of ghosting. "It's strange because it’s like where did they go?" Blondy said.Experts say part of the reason for the sudden disappearing act is actually good news: a stronger economy. "There’s more jobs for people so they have more options, they have more choices," Blondy said. However, the toll the trend takes on those who get ghosted is more than just the equivalent of an emotional rollercoaster. "A lot of these candidates we get really excited about, so to have them not show up can be disappointing and also expensive," Blondy said. "We start with the group interview, we have them come back to do a work assessment. the HR person spends time creating a schedule, the onboarding…we’ve already spent a couple of hundred dollars before they even walk in the door their first day." 1166

SAN MARCOS, Calif. (KGTV) -- A North County family has a message for a prankster who lit a firework on their doorstep. The Bennetts family's security video caught what appeared to be a teenager lighting a firework and setting it down on the porch of their San Marcos home last Friday night. The teen is then seen ringing the doorbell before running off. “I don’t know exactly what kind of firework it was. But it made a pretty big boom,” homeowner Melanie Bennetts said. She said there was a bench with pillows on their porch that could have caught on fire. Her husband was home at the time but didn’t answer the door. The Bennetts’ have two teenagers, but they did not recognize the young man in the security video. Bennetts said kids have egged and toilet-papered their house in the past. She doesn’t make a big deal about it because she understands kids will be kids. But in this case, she hopes kids and parents take note of the incident, and that it becomes a lesson that some actions could have serious consequences. “We live in Southern California where fire is not a joke,” she said. 1104

  

#Chargers HC Anthony Lynn says Colin Kaepernick “fits the style of quarterback for the system we’ll be running.” Also said he’s happy with the 3 QBs they have on the roster but can always look to improve that position. Lynn also said he hasn’t had contact with Colin.— Omar Ruiz (@OmarDRuiz) June 17, 2020 313

  

You're stressed out. You look around frantically, sure that the walls are closing in on you. There appears to be no way out. You look around and see friends and loved ones trapped in a similar situation, and wonder not only how you all wound up in this mess, but why it was that you actually paid to put yourself in this situation.So where are you, an escape room? Not quite. You're in "Escape Room." The movie. Your plight is the accumulation of questionable choices, and your price is being stuck in a bizarro, idiotic mess for nearly two hours.Game over. You lose.A movie that only wound up in theaters because it's the first Friday of the year — the ninth batter slot of the movie world — "Escape Room" manages to meet lowered expectations and somehow manage to slide right below them.Its C-level stars swap insipid one-liners, perish in a sloppy mess of mediocre special effects and struggle to solve puzzles that range from slap-you-in-the-face obvious to head-shakingly obtuse. Playing like a second-rate "Saw" sequel, it stretches its this premise until it snaps, taking your attention along with it.Escape rooms are famous for taking groups of friends and loved ones and transforming them into bitter enemies who can no longer stand the sight of one another. Their obtuse, teamwork-oriented puzzles have a dastardly way of breeding distrust and contempt in the name of "team building."It's only natural that a movie based on the concept would be similarly sinister and counterproductive. Moviegoers expecting something coherent and competent will leave the theater bitter and unfulfilled. Tyler Labine, Logan Miller, Deborah Ann Woll, Taylor Russell, Logan Miller and Nik Dodani play the hapless contestants who find themselves tricked into taking part in a real-life escape room series that promises ,000 to the winners. Second prize, they quickly learn, is swift, grisly death.These sure aren't the sort of rooms you'll find down at the local strip mall. Contestants are torched, dropped, gassed and electrocuted, usually due to their own idiocy. You start to feel guilty for rooting for the escape room itself, rather than any of the dopey characters.Worse still, director Adam Robitel and his screenwriters go for a twist ending that succeeds in unpredictability only because it's so incomprehensible. By the time the finale hits -- and it makes impact with a thud -- you're so worn out that you're not even annoyed by the inanity. You're simply grateful the end credits are at hand, and with it your sweet escape.RATING: 1.5 stars out of 4 2568
