     — 

    A fake image purporting to show an explosion near the Pentagon was shared by multiple verified Twitter accounts on Monday, causing confusion and leading to a brief dip in the stock market. Local officials later confirmed no such incident had occurred.

    The image, which bears all the hallmarks of being generated by artificial intelligence, was shared by numerous verified accounts with blue check marks, including one that falsely claimed it was associated with Bloomberg News.

    “Large explosion near the Pentagon complex in Washington DC. – initial report,” the account posted, along with an image purporting to show black smoke rising near a large building.

    The account has since been suspended by Twitter. It was unclear who was behind the account or where the image originated. A spokesperson for Bloomberg News said the account is not affiliated with the news organization.

    Under owner Elon Musk, Twitter has allowed anyone to obtain a verified account in exchange for a monthly payment. As a result, Twitter verification is no longer an indicator that an account represents who it claims to represent.

    Twitter did not respond to a request for comment.

    The false reports of the explosion also made their way to air on a major Indian television network. Republic TV reported that an explosion had taken place, showing the fake image on its air and citing reports from the Russian news outlet RT. It later retracted the report when it became clear the incident had not taken place.

    “Republic had aired news of a possible explosion near the Pentagon citing a post & picture tweeted by RT,” the outlet later posted on its Twitter account. “RT has deleted the post and Republic has pulled back the newsbreak.”

    In a statement Tuesday, the RT press office said, “As with fast-paced news verification, we made the public aware of reports circulating and once provenance and veracity were ascertained, we took appropriate steps to correct the reporting.”

    In a post on the Russian social media platform VKontakte Tuesday, RT tried to make light of its apparent error.

    “Is the Pentagon on fire? Look, there’s a picture and everything. It’s not real, it’s just an AI generated image. Still, this picture managed to fool several major news outlets full of clever and attractive people, allegedly,” a post from RT read.

    In the moments after the image began circulating on Twitter, the US stock market took a noticeable dip. The Dow Jones Industrial Average fell about 80 points between 10:06 a.m. and 10:10 a.m., fully recovering by 10:13 a.m. Similarly, the broader S&P 500 went from up 0.02% at 10:06 a.m. to down 0.15% at 10:09 a.m.. By 10:11 a.m., the index was positive again.

    The building in the image does not closely resemble the Pentagon and, according to experts, shows signs it may have been created using AI.

    “This image shows typical signs of being AI-synthesized: there are structural mistakes on the building and fence that you would not see if, for example, someone added smoke to an existing photo,” Hany Farid, a professor at the University of California, Berkeley, and digital forensic expert told CNN.

    The fire department in Arlington, Virginia, later responded in a tweet, stating that it and the Pentagon Force Protection Agency were “aware of a social media report circulating online about an explosion near the Pentagon. There is NO explosion or incident taking place at or near the Pentagon reservation, and there is no immediate danger or hazards to the public.”

  • Ron DeSantis, facing challenges at home, will test presidential ambitions overseas | CNN Politics

    Ron DeSantis, facing challenges at home, will test presidential ambitions overseas | CNN Politics

    [ad_1]



    CNN
     — 

    After a trying week for his national political ambitions, Gov. Ron DeSantis is headed abroad this week for a series of visits to allied nations – an opportunity for the Florida Republican to step onto the international stage for the first time as a likely presidential contender.

    The official purpose behind DeSantis’ globetrotting is for an “international trade mission,” according to his office. DeSantis, as well as first lady Casey DeSantis and two representatives from his administration, will travel to Japan, South Korea, Israel and the United Kingdom to meet with officials and chat up potential business partnerships.

    “This trade mission will give us the opportunity to strengthen economic relationships and continue to demonstrate Florida’s position as an economic leader,” the governor said in a news release Thursday.

    DeSantis met with Japanese Prime Minister Fumio Kishida on Monday in Tokyo where the two exchanged views on “regional affairs.” Kishida said he hopes DeSantis’ “visit to Japan will lead to the further strengthening of Japan-US and Japan-Florida relationship,” according to a Japanese foreign ministry statement published on Monday.

    While in Israel, DeSantis will also keynote an event hosted by The Jerusalem Post and the Museum of Tolerance Jerusalem. The appearance there comes at a time of increased tension between the US and its Middle East ally over Israeli Prime Minister Benjamin Netanyahu’s judicial overhaul proposal.

    The trip will spotlight DeSantis’ foreign policy credentials as he inches toward a White House bid. DeSantis rose to the national consciousness as a pandemic contrarian and by leading his state through a series of cultural fights, but his views on world affairs had been less scrutinized until recently, when the governor offered a series of contradicting opinions on the war in Ukraine.

    DeSantis’ remark that support for Ukraine was not of “vital” national interest set off alarm bells among hawkish Republicans in Congress before the governor backtracked in an interview with Piers Morgan and called Russian President Vladimir Putin a war criminal. He further obscured his position a few days later by dismissing the war as a fight over the “borderlands.”

    Over his nearly six years as a congressman in Washington, DeSantis, a former Navy lawyer stationed in both Guantanamo Bay and Iraq, served on the House Foreign Affairs Committee, where he was often critical of President Barack Obama’s overseas agenda. As governor, he has urged hard-line policies against communist governments in Cuba and China, most recently banning TikTok on state government devices and pushing legislation that would make it illegal for Chinese nationals to buy property in Florida.

    And even as he is scheduled to meet with allies to encourage business with his state, DeSantis on Friday poked fun at a United Nations committee resolution that criticized an anti-riot law he championed as governor.

    “I wear that criticism as a badge of honor,” he said at an event hosted by The Heritage Foundation outside Washington.

    DeSantis’ trip abroad marks the first time he has left US soil on official business since the early days of his first term as governor in 2019, when he visited Israel along with the state’s elected cabinet members. As an elected official, DeSantis has not visited a foreign country other than Israel.

    DeSantis’ predecessor, now-US Sen. Rick Scott, embarked on more than a dozen trade missions during his tenure as governor. DeSantis, though, has focused largely on issues at home while also dealing with a coronavirus outbreak that significantly restricted travel for much of his first term.

    As he now prepares for his first visits to Europe and East Asia as governor, DeSantis is leaving behind the most difficult stretch so far of the unofficial rollout of his expected presidential campaign, as well as challenges in his home state that have caused critics to raise questions about his extensive recent travel.

    Some key donors have publicly expressed reservations about DeSantis’ chances in a primary against Donald Trump, who continues to hammer his onetime ally on social media. The former president last week upstaged DeSantis’ return to Capitol Hill to seek support from within the chamber he once served in by rolling out a string of congressional endorsements – including a handful from Florida lawmakers. Eleven Florida Republicans have endorsed Trump over DeSantis so far – including seven last week.

    DeSantis has also faced scrutiny for his response this month to torrential storms – described as a 1-in-1,000-year rainfall event – that left Fort Lauderdale and surrounding communities underwater. Amid the severe flooding, DeSantis took his book tour to Ohio and spoke at a fundraiser for New Hampshire Republicans – returning to Florida in between trips for a late-night, closed-door signing of a six-week abortion ban – and said little publicly about the storms.

    “Fort Lauderdale is under water and DeSantis is campaigning in Ohio right now instead of taking care of the people suffering in his state,” Donald Trump Jr., the former president’s son, tweeted earlier this month.

    The storms also caused gasoline shortages throughout South Florida, leading the state’s US senators, both Republicans, to criticize the response, though without directly calling out DeSantis. Sen. Marco Rubio called the situation “crazy,” adding, “They gotta get this thing fixed.”

    “Florida families shouldn’t have uncertainty about their next tank of gas. Every resource available should be deployed to fix this,” Scott tweeted.

    Asked about the comments from Florida’s senators, DeSantis spokesman Bryan Griffin told CNN that “the state emergency response apparatus has been at work since the flooding occurred and continues in full swing responding to the needs of the localities as they are communicated to us. The governor issued a state of emergency the day after the flooding occurred.”

    On Saturday, DeSantis requested a major disaster declaration from the Biden administration.

    Meanwhile, in his state’s capital of Tallahassee, the Florida Legislature is nearing the end of a 60-day session where GOP lawmakers have been tasked with helping DeSantis rack up policy victories before he launches a campaign for president. He has already signed several of those bills, including the abortion ban, a measure to allow Floridians to carry concealed guns in public and an overhaul of the state’s tort laws.

    With DeSantis mostly on the road, though, several of his priorities appear to have stalled in the GOP-controlled legislature. A bill that would make it easier to sue media outlets for libel hasn’t moved in weeks. State lawmakers have also balked at a provision in DeSantis’ immigration package that would eliminate in-state tuition for undocumented residents.

    US Rep. Greg Steube, who previously served in the Florida Senate and endorsed Trump last week, accused state lawmakers on Friday of “carrying the water for an unannounced presidential campaign.”

    “Your constituents voted you into those positions to represent them, not to kowtow to the presidential ambitions of a Governor!” the GOP lawmaker tweeted. “Be strong and courageous, the people of Florida will thank you.”

    Appearing unfazed by the chatter, DeSantis on Friday rattled off his conservative victories as governor before a friendly audience at the Heritage Foundation event.

    DeSantis also looked briefly ahead to the 2024 race, laying out what was at stake in the next presidential election and suggesting the country needed a “determined and disciplined chief executive to root out politicization and corruption throughout the old executive branch” – a likely jab at the distracted and often chaotic presidency of Trump.

    “We need to reject the pessimism that is in the air about our country’s future,” DeSantis said. “Because at the end of the day, decline is a choice, success is attainable and freedom is worth fighting for.”

  • Chinese police detain man for allegedly using ChatGPT to spread rumors online | CNN Business

    Chinese police detain man for allegedly using ChatGPT to spread rumors online | CNN Business

    [ad_1]


    Hong Kong
    CNN
     — 

    Police in China have detained a man they say used ChatGPT to create fake news and spread it online, in what state media has called the country’s first criminal case related to the AI chatbot.

    According to a statement from police in the northwest province of Gansu, the suspect allegedly used ChatGPT to generate a bogus report about a train crash, which he then posted online for profit. The article received about 15,000 views, the police said in Sunday’s statement.

    ChatGPT, developed by Microsoft

    (MSFT)    -backed OpenAI, is banned in China, though internet users can use virtual private networks (VPN) to access it.

    Train crashes have been a sensitive issue in China since 2011, when authorities faced pressure to explain why state media had failed to provide timely updates on a bullet train collision in the city of Wenzhou that resulted in 40 deaths.

    Gansu authorities said the suspect, surnamed Hong, was questioned in the city of Dongguan in southern Guangdong province on May 5.

    “Hong used modern technology to fabricate false information, spreading it on the internet, which was widely disseminated,” the Gansu police said in the statement.

    “His behavior amounted to picking quarrels and provoking trouble,” they added, explaining the offense that Hong was accused of committing.

    Police said the arrest was the first in Gansu since China’s Cyberspace Administration enacted new regulations in January to rein in the use of deep fakes. State broadcaster CGTN says it was the country’s first arrest of a person accused of using ChatGPT to fabricate and spread fake news.

    Formally known as deep synthesis, deep fake refers to highly realistic textual and visual content generated by artificial intelligence.

    The new legislation bars users from generating deep fake content on topics already prohibited by existing laws on China’s heavily censored internet. It also outlines take down procedures for content considered false or harmful.

    The arrest also came amid a 100-day campaign launched by the internet branch of the Ministry of Public Security in March to crack down on the spread of internet rumors.

    Since the beginning of the year, Chinese internet giants such as Baidu

    (BIDU)     and Alibaba

    (BABA)    have sought to catch up with OpenAI, launching their own versions of the ChatGPT service.

    Baidu unveiled “Wenxin Yiyan” or “ERNIE Bot” in March. Two months later, Alibaba launched “Tongyi Qianwen,” which roughly translates as seeking truth by asking a thousand questions.

    In draft guidelines issued last month to solicit public feedback, China’s cyberspace regulator said generative AI services would be required to undergo security reviews before they can operate.

    Service providers will also be required to verify users’ real identities, as well as providing details about the scale and type of data they use, their basic algorithms and other technical information.

  • Hot box detectors didn’t stop the East Palestine derailment. Research shows another technology might have | CNN

    Hot box detectors didn’t stop the East Palestine derailment. Research shows another technology might have | CNN

    [ad_1]



    CNN
     — 

    A failing, flaming wheel bearing doomed the rail car that derailed and created a catastrophe in East Palestine earlier this month, but researchers have offered a solution to the faulty detectors that experts say could have averted the disaster unfolding in the small Ohio town.

    These wayside hot box detectors, stationed on rail tracks every 20 miles or so, use infrared sensors to record the temperatures of railroad bearings as trains pass by. If they sense an overheated bearing, the detectors trigger an alarm, which notifies the train crew they should stop and inspect the rail car for a potential failure.

    So why did these detectors miss a bearing failure before the catastrophe?

    An investigation into hot box detectors published in 2019 and funded by the Department of Transportation found that one “major shortcoming” of these detectors is that they can’t distinguish between healthy and defective bearings, and temperature alone is not a good indicator of bearing health.

    “Temperature is reactive in nature, meaning by the time you’re sensing a high temperature in a bearing, it’s too late, the bearing is already in its final stages of failure,” Constantine Tarawneh, director of the University Transportation Center for Railways Safety (UTCRS) and lead investigator of the study, told CNN.

    As part of the investigation, the UTCRS researchers developed a new system to better detect a bearing issue long before a catastrophic failure. The key: measuring the bearing’s vibration in addition to its temperature and load.

    The vibration of a failing bearing, Tarawneh says, often begins intensifying thousands of miles before a catastrophic failure. So his team created sensors that can be placed on board each rail car, near the bearing, to continuously monitor its vibration throughout its travels.

    “If you put an accelerometer on a bearing and you’re monitoring the vibration levels, the minute a defect happens in the bearing, the accelerometer will sense an increase in vibration, and that could be, in many cases, up to 100,000 miles before the bearing actually fails,” he said.

    Tarawneh, who argues the technology should be federally mandated, says had it been on board Norfolk Southern’s line it would have prevented the derailment in East Palestine.

    “It would have detected the problem months before this happened,” he said. “There wouldn’t have been a derailment.”

    A preliminary report from the East Palestine derailment, released Thursday by the National Transportation Safety Board, found hot box sensors detected that a wheel bearing was heating up miles before it eventually failed and caused the train to derail. But the detectors didn’t alert the crew until it was too late.

    The bearing, according to the report, was 38 degrees above ambient temperature when it passed through a hot box 30 miles outside East Palestine. No alert went out, the NTSB said.

    Ten miles later, the next hot box detected that the bearing had reached 103 degrees above ambient. Video of the train recorded in that area shows sparks and flames around the rail car. Still, no alert went to the crew.

    It wasn’t until a further 20 miles down the tracks, as the train reached East Palestine, that a hot box detector recorded the bearing’s temperature at 253 degrees above ambient and sent an alarm message instructing the crew to slow and stop the train to inspect a hot axle, the report said.

    The crew slowed the train, the report added, leading to an automatic emergency brake application. After the train stopped, the crew observed the derailment.

    The reason those first two hot box readings didn’t trigger an alert, the report said, is because Norfolk Southern’s policy is to only stop and inspect a bearing after it has reached 170 degrees above ambient temperature. The NTSB is planning to review Norfolk Southern’s use of wayside hot box detectors, including spacing and the temperature threshold that determines when crews are alerted.

    “Had there been a detector earlier, that derailment may not have occurred,” said NTSB Chair Jennifer Homendy at a Thursday press conference.

    In a statement responding to the NTSB report, Norfolk Southern stressed that its hot box detectors were operating as designed, and that those detectors trigger an alarm at a temperature threshold that is “among the lowest in the rail industry.” CNN has reached out to Norfolk Southern for comment on vibration sensor technology.

    Hot box detectors are unregulated, so companies like Norfolk Southern can turn them on and off at their own discretion and choose the temperature threshold at which crews receive an alert.

    There are several causes for overheated roller bearings, including fatigue cracking, water damage, mechanical damaging, a loose bearing or a wheel defect, according to the NTSB, and the agency says they’re investigating what caused the failure in East Palestine.

    “Roller bearings fail, but it is absolutely critical for problems to be identified and addressed early so these aren’t run until failure,” Homendy said. “You cannot wait until they’ve failed. Problems need to be identified early, so something catastrophic like this does not occur again.”

    Hum Industrial Technology, a rail car telematics company, has licensed the vibration sensor technology created by Tarawneh and his team. And it has launched pilot programs with several rail companies. But at this point, those sensors are on very few trains operating in the United States, which Tarawneh largely blames on the cost of retrofitting and monitoring cars and what he sees as companies prioritizing profit.

    It’s not clear exactly what it would cost to retrofit every train car in operation with sensors today, but Hum Industrial Technology stressed that it would cost less to put a sensor on a bearing than to replace a bearing.

    “They see it as, well, why should we do it if it’s not mandated?” Tarawneh said. “It’s like a lot of people are saying, ‘well, I’m willing to take the risk. It’s not that many derailments per year.’”

    But Steve Ditmeyer, a former Federal Railroad Administration official, says equipping every rail car with on board sensors may not be financially feasible.

    “What they’re proposing will work, but it’s very, very expensive,” Ditmeyer told CNN. “And one does have to take cost into consideration.”

    It would take more than 12 million on board sensors, according to Tarawneh, to fully equip the roughly 1.6 million rail cars in service across North America.

    Ditmeyer says railroads should invest more heavily in wayside acoustic bearing detectors, which sit along the tracks – much like hot box detectors – and monitor the sound of passing trains. They listen for noise that indicates a bearing failure well before a potential catastrophe.

    As of 2019, only 39 acoustic bearing detectors were in use across North America compared to more than 6,000 hot box detectors, according to a 2019 DOT report.

    “They are the only way that I can think of that would have prevented the accident by having caught a failing bearing earlier,” Ditmeyer said.
