As we drive down the eerily deserted Hong Kong-Zhuhai-Macau Bridge, the murky waters of the Pearl River Delta stretch as far as the eye can see. There is no land in sight.Spanning 34 miles (55 kilometers), this is the longest sea-crossing bridge ever built. Guo Xinglin, assistant director and senior engineer at the Hong Kong-Zhuhai-Macao Bridge Authority, meets us half way along. As we are buffeted by a strong wind, the tough conditions his construction crew experienced, as they perched on precarious platforms, working miles from land and high over the water, are evident.Guo is visibly proud of his country's monumental achievement. 647

Authorities are investigating interference with police radio communications, websites and networks used by law enforcement and other officials during recent U.S. protests over the death of George Floyd in Minneapolis.Although the efforts to disrupt police radios and take down websites in Minnesota, Illinois and Texas aren’t considered technically difficult hacks, federal intelligence officials warned that law enforcement should be ready for such tactics as protests continue.Authorities have not yet identified anyone responsible or provided details about how the disruptions were carried out. But officials were particularly concerned by interruptions to police radio frequencies during the last weekend of May as dispatchers tried to direct responses to large protests and unrest that overshadowed peaceful demonstrations.During protests in Dallas on May 31, someone gained access to the police department’s unencrypted radio frequency and disrupted officers’ communications by playing music over their radios, according to a June 1 intelligence assessment from the U.S. Department of Homeland Security.Dallas police did not respond to questions about the incident.The assessment, which was obtained by The Associated Press, attributes the Dallas disruption to “unknown actors” and does not say how they accessed the radio frequency. It warned that attacks of various types would likely persist.“Short-term disruptive cyber activities related to protests probably will continue — various actors could be carrying out these operations — with the potential to use more impactful capabilities, like ransomware, or target higher profile networks,” the assessment warns.The assessment noted similar problems with Chicago police’s unencrypted radio frequencies during large downtown protests on May 30 followed by reports of arson, theft and vandalism. Chicago police also have not said how the radio frequencies were accessed, but an official with the city’s Office of Emergency Management and Communications told the Chicago Sun-Times that the tactic was “very dangerous.”Police around the country have encrypted their radio communications, often arguing that it’s a way to protect officers and block criminals from listening in on widely available phone apps that broadcast police radio channels. But media outlets and local hobbyists have been frustrated by the changes, which also prevent them from reporting on issues pertaining to public safety.The Department of Homeland Security issued a separate warning this week reporting that personal information of police officers nationwide is being leaked online, a practice known as “doxxing.” According to the report obtained by the AP, information shared on social media included home addresses, email addresses and phone numbers.Law enforcement agencies have been targeted by online pranksters or hackers in recent years, including by some who claimed to be motivated by on-the-ground protests against police tactics. For example, the hacking collective Anonymous claimed responsibility for the defacement of local police departments’ websites in 2012 as protesters clashed with officers during the Occupy Wall Street movement.Individuals who self-identified as being part of the collective also claimed to have accessed dispatch tapes and other Ferguson Police Department records in 2014 after a white police officer shot and killed Michael Brown, an 18-year-old black man.Like other government entities, law enforcement agencies in recent years have been frequently targeted by ransomware attacks, in which a perpetrator virtually locks up a victim’s computer files or system and demands payment to release them.The prevalence of cyberattacks — which can cause physical damage or far-reaching disruption — and less severe online trickery, such as stealing passwords, has given law enforcement agencies more experience at fending off efforts to take down their websites or access critical information. But hackers adapt too, and governments with fewer resources than private companies often struggle to keep up, said Morgan Wright, chief security officer for the cybersecurity company SentinelOne.“The biggest concern they have right now is the safety of their communities, the safety of their officers,” Wright said of how law enforcement agencies view cyberthreats amid large demonstrations and unrest. “But if you look at what underpins everything we use to communicate, collaborate and operate, it’s all technology.”As large protests gathered steam after the May 25 death of Floyd, a handcuffed black man who died after a white Minneapolis police officer used his knee to pin his neck down for several minutes, Minnesota Gov. Tim Walz said state networks had been targeted. He described the activity as a “a very sophisticated denial of service attack.”But experts said the strategy of bombarding a website with traffic is common and doesn’t always take a high level of skill, counter to Walz’s description. Minnesota’s Chief Information Officer Tarek Tomes later said state services weren’t disrupted.But the efforts got a lot of attention, partly due to unverified online claims that Anonymous was responsible after years of infrequent activity. The decentralized group largely went quiet in 2015 but is still known globally based on headline-grabbing cyberattacks against Visa and MasterCard, the Church of Scientology and law enforcement agencies.Twitter users also made unverified claims that Anonymous was behind recent intermittent outages on the city government’s website in the Texas capital of Austin. Their posts indicated that the disruption was retribution for police officers shooting a 20-year-old black man in the head with a bean bag during a May 31 protest outside of police headquarters.The injured protester, identified by family as Justin Howell, remained hospitalized Wednesday in critical condition.The city’s IT department was looking into the site’s issues, but a spokesman said Monday that he couldn’t provide any information about the cause. He said the website was still experiencing a high volume of traffic.“You should have expected us,” an account purporting to be Anonymous’ posted on Twitter. It also warned that “new targets are coming soon.”The collective’s approach — anyone can act in its name — makes it difficult to verify the recent claims of responsibility. But Twitter accounts long affiliated with Anonymous shared them, said Gabriella Coleman, a professor at McGill University in Montreal who has studied the Anonymous movement for years.People with more advanced and disruptive hacking skills often drove peak instances of attention for Anonymous, and it’s not clear whether that type of activity will resume, she added.“There’s a lot of things going on in the background, people are chatting,” Coleman said. “Whether or not it materializes is another question. But certainly people are kind of aroused and talking and connecting.”___Foody reported from Chicago.

AVENAL, Calif. (AP) — Authorities say an inmate at a central California prison died of complications from the coronavirus Saturday, becoming the state’s 79th person to have a fatal case of COVID-19 while they were incarcerated. The Avenal State Prison inmate died at a hospital. The prisoner’s name was not released. There have been 15,872 confirmed cases of the coronavirus in the state prison system. Advocates say jails and prisons nationwide are prime locations for the virus to spread between inmates and staff. Officials have released hundreds of inmates to decrease jail and prison populations across the country during the pandemic. 648

ATLANTA, Ga. – A top official with the Centers for Disease Control and Prevention (CDC) said Wednesday that experts are seeing a “distressing trend” as coronavirus cases surge across the United States, particularly in the Midwest.“Unfortunately, we're seeing a distressing trend here in the United States,” said Dr. Jay Butler, Deputy Director for Infectious Diseases. “Smaller, more intimate gatherings of family, friends and neighbors may be driving transmission as well, especially as they move indoors.”Butler also urged Americans to continue taking the necessary precautions to prevent the spread of the coronavirus, like practicing social distancing, washing your hands and wearing masks.“I recognize we are all getting tired of the impact that COVID-19 has had on our lives, we get tired of wearing masks, but it continues to be as important as it’s ever been and I’d say it’s more important than ever as we move into the fall season.”Butler made the comments during a press briefing with CDC Director Dr. Robert Redfield and Health and Human Services (HHS) Secretary Alex Azar.CDC, HHS give an update on COVID-19 response https://t.co/YxLSMGZgbs— Reuters Science News (@ReutersScience) October 21, 2020 During the briefing, Azar and Redfield discussed Operation Warp Speed, a partnership initiated by the Trump administration to accelerate the testing, supply, development and distribution COVID-19 vaccines, therapeutics and diagnostics.The goal of partnership is to produce and deliver 300 million doses of a safe and effective vaccine with initial doses available by January 2021, according to the HHS website.Azar provided an updated timeline on when we can expect vaccine to be distributed and who will receive the first doses. According to him, a vaccine would be widely available by late March or early April.“We expect that we would have by the end of this year, enough vaccine that is FDA authorized, to be able to vaccinate all of our vulnerable, the most vulnerable individuals,” said Azar. “Then by the end of January, we expect we’ll have enough to vaccinate all seniors as well as our health care workers and first responders. And by the end of March to early April, enough vaccine for all Americans who would want to take a vaccine.”Wednesday’s briefing comes as many states report increases in the number of COVID-19 cases. The U.S. has surpassed 8.3 million cases and more than 221,500 people have died across the nation from the disease, according to an ongoing tally by Johns Hopkins University.Experts are concerned there may be a major spike in cases during the fall and winter months, which will strain the country's health care system, which will also be caring for flu patients.With many people still struggling amid the pandemic, Congress and the Trump administration still have not come to a deal on another COVID-19 relief bill. As for the Senate, Majority Leader Mitch McConnell has signaled his chamber may not support the potential deal. 2983

Attorney General Jeff Sessions is once again under scrutiny on Capitol Hill regarding his candor about Russia and the Trump campaign amid revelations that he rejected a suggestion to convene a meeting between Russian President Vladimir Putin and Donald Trump last year.According to court filings unsealed this week, Trump campaign foreign policy adviser George Papadopoulos suggested at a March 2016 meeting that he could use his connections to set up a meeting between Putin and Trump with the then-GOP candidate's national security team. An Instagram picture on Trump's account shows Sessions attended the meeting at which Papadopoulos made the suggestion.After Trump declined to rule out the idea, Sessions weighed in and rejected the proposed meeting, according to a person who attended. 799
