TAMPA, Fla. (AP) — A Florida teen identified as the mastermind of scheme that gained control of Twitter accounts of politicians, celebrities and technology moguls has pleaded not guilty to multiple counts of fraud. Seventeen-year-old Graham Clark is accused of using the hijacked Twitter accounts to scam people around the world out of more than 0,000 in Bitcoin. He faces numerous charges including 17 counts of communications fraud and 11 counts of fraudulent use of personal information. Two other men were also charged in the case. Mason Sheppard, 19, of Bognor Regis, U.K., and Nima Fazeli, 22, of Orlando were charged separately last week in California federal court.Court papers in the California cases say Fazeli and Sheppard brokered the sale of Twitter accounts stolen by a hacker who identified himself as “Kirk,” and said he could “reset, swap and control any Twitter account at will” in exchange for cybercurrency payments, claiming to be a Twitter employee.The documents do not specify Kirk’s real identity but say he is a teen being prosecuted in the Tampa area.Twitter has said the hacker gained access to a company dashboard that manages accounts by using social engineering and spear-phishing smartphones to obtain credentials from “a small number” of Twitter employees “to gain access to our internal systems.” Spear-phishing uses email or other messaging to deceive people into sharing access credentials.The prosecution believes Clark called a Twitter employee and was able to convince the employee he was a coworker, according to the Wall Street Journal.A blog post from Twitter last week shared some details of the hack. "Using the credentials of employees with access to these tools, the attackers targeted 130 Twitter accounts, ultimately Tweeting from 45, accessing the DM inbox of 36, and downloading the Twitter Data of 7." Clark was arrested Friday and entered the not-guilty pleas Tuesday. He remains in jail with bond set at 5,000. A bond hearing is set for Wednesday. 2013

TAMPA, Fla. — Air conditioning units may be contributing to the spread of COVID-19, especially in the southern part of the United States, according to a Harvard epidemiologist.Dr. Edward Nardell is a professor in the Departments of Environmental Health and Immunology and Infectious Diseases at the Harvard T.H. Chan School of Public Health. He's done in-depth research on how air conditioning units contribute to the spread of airborne infections.Nardell said air conditioning can help airborne viruses spread in three ways.First, people go inside to cool down, when you are much safer outdoors, Nardell said. Now, we're seeing more people indoors because of the high heat and humidity, specifically in the southern states like Florida.The second problem is that air conditioning brings in very little outside air, according to Nardell. While this isn't a major problem inside your own home, it can be especially problematic in corporate settings."It just isn't economically possible to bring in outside air, recirculate it and dehumidify it," he said.Lastly, he said when people are indoors, you're often not spaced out safely as you would be outdoors."You are not socially distanced as much, but you're re-breathing the same air that someone else just exhaled," Nardell said. "We call it rebreathed air fraction, and if someone is infectious, often asymptomatic, you're going to be rebreathing their small particles."Nardell also said air conditioning units can generate air currents that can carry large particles even further, similar to what researchers found contributed to the spread of the novel coronavirus disease in an air-conditioned restaurant in Guangzhou, China, involving three family clusters.On the Department of Homeland Security's website, this tool can be used to estimate how long the virus would be expected to remain stable while airborne.Now, the Centers for Disease Control and Prevention is recommending restaurants increasing the distance between tables and improving ventilation.The use of germicidal lamps, a technology that Nardell said is almost 100 years old, has been proven effective in protecting against tuberculosis infection and is already in use in some settings to fight COVID-19.The lamps are set up to shine horizontally, high in the room where sterilization is needed. Air currents, stirred in part by warmth from human bodies, circulate up to the ceiling, where the ultraviolet light kills floating pathogens, and then back down again.This technology, Nardell said, is not only proven, but it can also be deployed cheaply and easily in a number of settings as society reopens.This story was originally published by Lauren Rozyla at WFTS. 2691

Strong winds and heavy rain have battered parts of Italy, causing nine deaths and the worst flooding seen in Venice for at least a decade.Schools have been closed around the country and the authorities have warned against non-essential travel as the Civil Protection Agency issued multiple weather warnings.Two young people died south of Rome when a tree hit their car, while another person was killed in the nearby town of Terracina as winds brought down scores of pine trees. Among the other victims was a 21-year-old man who was hit by a falling tree while walking in Naples, while a woman died after being struck by debris blown off a building in the northern region of Liguria.A volunteer firefighter who was helping with the emergency response in San Martino in Badia in the country's north is also reported to have died.Much of the Italian lagoon city of Venice was engulfed with water after high tides and strong winds caused the most severe flooding for years. 977

Swishing with mouthwash can help freshen that mask breath, and, new research suggests, reduce the amount of coronavirus in the mouth and may help reduce the spread of the virus.Physicians and scientists at the Penn State College of Medicine studied the effect of rinsing with a neti pot, peroxide sore-mouth cleansers, mouthwashes and a 1 percent solution of baby shampoo, which is often used by head and neck doctors to rinse the sinuses. All of the products are currently available to consumers, many over-the-counter.They found several of the nasal and oral rinses had “a strong ability to neutralize human coronavirus, which suggests that these products may have the potential to reduce the amount of virus spread by people who are COVID-19 positive,” the college said in a written statement.Researchers used human coronaviruses that are similar to SARS-CoV-2, the coronavirus strain that causes COVID-19. The “outer envelopes of the human coronavirus tested and SARS-CoV-2 are genetically similar,” the researchers stated.“While we wait for a vaccine to be developed, methods to reduce transmission are needed,” said Craig Meyers, the professor who led the study. “The products we tested are readily available and often already part of people’s daily routines.”The study looked at the effectiveness of the various products when they interact with a solution containing a strain of human coronavirus at intervals of 30 seconds, one minute and two minutes.The 1 percent baby shampoo solution inactivated more than 99.9 percent of the human coronavirus after being in contact for two minutes. The mouthwash and gargle products were also 99.9 percent effective in inactivating the human coronavirus, but after only 30 seconds of contact.The findings from Penn State College of Medicine add to findings earlier this year that showed certain types of oral rinses could inactivate SARS-CoV-2.Meyers said the next step in this line of research is to evaluate products like mouthwashes in COVID-19 positive patients to see if they reduce the viral load.The study’s results were published this week in the Journal of Medical Virology. 2137

Students who survived the school shooting in Florida are using their voices to try and spur change. It’s young voices, that haven’t heard before who are speaking up.Seven seniors from Marjory Stoneman Douglas High School — Jack Haimowitz, Ronnie Froetschel, Vincent Frettoloso, Matthew Horowitz, Cole Sumner, Cain DeLima and Joey Mondelli — say they hope the tragedy spurs change.“The day that changed everything,” Mondelli said, when asked how he wants people to remember the day of the shooting.“I don’t want them to look at it as a statistic,” Somner said. “I want people to see this as the last one. I want people to look back at that day because that was the end,” Haimowitz said. These are seven faces of survival, family, and ultimately, they hope, change. “If there’s anyone that can change the outcome of situations, it’s going to be Parkland and we will change it,” Frettoloso said. “It’s tough when you’re by yourself so when you’re all together, it kind of get your mind off it,” DeLima said. Tonight, they’re freshly blonde, for their friend and victim, Joaquin Oliver. “His favorite artist was Frank Ocean, when he dropped his album 'Blonde,' it was about the time Joaquin dyed his hair this color,” Haimowitz said. “He was everyone’s friend.”“That kid didn’t know a single thing about lacrosse and he was out there screaming like he’s been playing it for the last 18 years,” Haimowitz said. On Wednesday, they grew up fast. “It’s a race for maturity. No one really told us there was going to be a starting line or a starting gun, they just expected us to go,” Haimowitz said. First, they will grieve. They have 17 funerals to attend. When the time’s right, perpetuate change. “An assault rifle, that’s a weapon made with intent to murder and harm people. So once we feel ready, we’re going to make our voice heard that our platform is built upon making sure weapons like these can’t get in the hands of people again,” Haimowitz said.  2042
