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.

Authorities believe they have found a package addressed to former Vice President Joe Biden that was considered suspicious due to its similarities to other packages sent this week to prominent Democrats and CNN, law enforcement officials said Thursday.The package was misaddressed and returned to sender, two law enforcement sources previously told CNN.Also on Thursday, a suspicious package addressed to actor-director Robert De Niro was reported at the Manhattan building where his production company is based, and its marking and contents appear similar to pipe bomb packages recently mailed nationwide to top Democrats, two law enforcement sources said.Law enforcement authorities are treating the series of bombs as a domestic terror matter and are advising the public to remain vigilant.Devices sent to former President Barack Obama, Hillary Clinton, former Attorney General Eric Holder, California Democratic Rep. Maxine Waters and Democratic donor George Soros showed the presence of a sulfur substance, which could have exploded, a law enforcement official said.The devices are believed to be pipe bombs, inherently unstable, and at risk of being set off just by handling.The FBI's counterterrorism division is leading the investigation Thursday into the packages and the agency says it's possible additional packages were mailed to other locations.The motive is unknown, but the recipients are all prominent targets of right-wing criticism and, in many cases, of President Donald Trump himself. The package found at CNN's New York bureau in the Time Warner Center was addressed to former CIA Director John Brennan, city and local law enforcement officials said.At the White House, Trump vowed Wednesday that "we will spare no resources or expense" to pursue the perpetrator.The-CNN-Wire 1803

ATLANTA, Ga. -- Musicians across the country performed for voters to bring unity and hope in a divisive time."Music is therapeutic," said professional saxophonist Christopher King. "It's like that one time that we can all come together whether we're Democrat or Republican."After months of divisive politics, King and other musicians came together through Play For The Vote. Their mission: lift worries and burdens from voters' shoulders and create a different feeling at the polls this Election Day."With everything we've been through since the beginning of this year, you can turn a negative into a positive," said King of this moment in history.Poll workers across Atlanta expected crowds of voters lined up around the building, but the day was quiet. The average wait was under five minutes. For musicians Ally Jenkins and Brian Raddock, performing on Election Day, even to a small crowd, was a moment of triumph, especially in a time where their life’s work has been slipping through their fingers."It's been a nightmare," said Jenkins, a violinist. "Everything was canceled within like three days of each other, and this is tens of thousands of dollars of income and also our purpose for living."Her longtime friend and fellow musician, Brian Raddock, feels her pain. "Devastating is putting it lightly, and in a lot of ways, and it's just because we're both freelancers. It's really show to show," he said.These two have played on Broadway and across New York City until COVID-19 shut their livelihoods down."I feel the most alive when I'm playing music, and to not have that with other people, it's it just kind of makes you feel a little bit lost when you're having to do it by yourself," said Raddock.But Election Day brought back a glimpse of normalcy. "To see some people smile while we're playing music and to use art to really help bring some more beauty into the world, I can't really even describe what it means. It's just wonderful," said Raddock.Their audience, mostly poll workers, agreed. "It was fun. It lifted your spirits to hear them. They're so talented, they're so good, and then to hear their plight, that's just something you hadn't even thought about," said Pattie Harris, an election volunteer.Thousands of musicians across the country are experiencing the same struggle. That’s why so many came together for Play for the Vote. Hundreds of artists volunteered across 48 states to play for voters, but also to start a movement lasting far beyond this year’s election."Music is the one universal language. There's just really a power of connection, that we can communicate, yet not know each other. I just hope that they walk away with a reminder that art and music is something that is a connector between all of us through all of our differences," said Raddock.A connection needing just one smile, just one look for these musicians to know: their life’s work is worth the fight.If you'd like to help support musicians struggling during the pandemic, you can help through Play for the Vote or through the Music Workers Alliance. 3066

As one of the world's most famous prehistoric monuments, Stonehenge still holds many secrets despite centuries of study. For the first time, new research is lifting the veil on the people who are buried at Stonehenge.The study was published in the journal Scientific Reports on Thursday.Much of the previous research around the monument in Wiltshire, England, has centered around how or why Stonehenge was built -- not the people buried there or who built it.But studying the human remains at Stonehenge is no easy task. In addition to dating back to 3,000 BC, the remains were also cremated. During the early phase of Stonehenge's history, it largely served as a cemetery.Fortunately, lead study author Christophe Snoeck, post-doctoral researcher at the Vrije Universiteit Brussel, combined his passions for archeology and chemical engineering to pioneer developments in archaeological analysis.The results revealed that 40% of the people buried at Stonehenge likely came from west Wales, the suggested origin of the site's smaller bluestones, and they most likely helped transport the stones and build Stonehenge. Signals from the bone analysis suggested that within the last ten years of their lives, these people were not living at Stonehenge nor originally from the area around Stonehenge, known as the Wessex region."Our results are the first one to provide direct evidence on the origin of those buried at Stonehenge, shedding light on the importance of the site in the Neolithic landscape," Snoeck said in an email. 1531

At least eight members of the same family were among the 26 people killed Sunday when a man armed with a rifle burst into the sanctuary of a church in Texas and started firing.The mass shooting left about 20 others wounded at the First Baptist Church in Sutherland Springs, about 30 miles east of San Antonio.The massacre killed about 4% of the small town's population. And no one at the church was left unscathed, Wilson County Sheriff Joe Tackitt said."I think nearly everyone had some type of injury," the sheriff told reporters Monday.Texas Gov. Greg Abbott called the slaughter "the largest mass shooting" in the state's history. But it's still unclear what motivated the killer.Latest developments-- The killer had in-laws who attended the church, but they were not present at the time of the massacre, the sheriff said.-- The shooter was first shot by an armed resident who confronted the gunman outside the church. The suspect then turned the gun on himself, authorities said. He was dressed in all-black tactical gear, including a ballistic vest, and was later found dead in his vehicle.-- The victims ranged in age from 5 to 72 years old, said Freeman Martin, a regional director with the Texas Department of Public Safety. The visiting pastor was among those killed, Tackitt said.-- The 14-year-old daughter of the church's regular pastor was among those killed, said Sherri Pomeroy, the girl's mother. Her parents were traveling out of state when the shooting occurred.-- At least eight of the people killed were members of one family, according to a relative and a community leader. Those relatives span three generations and include a woman who was about five months pregnant and three of her children.-- A witness told CNN affiliate KSAT that he and the armed resident pursued the gunman in a car chase for about 11 miles.-- Speaking from Japan, President Donald Trump expressed condolences for the victims during a Monday news conference and said he believes the shooting was caused by a "mental health problem," not an issue with US gun laws.Who was the shooter?The gunman has been identified as 26-year-old Devin Patrick Kelley, according to two law enforcement sources who have been briefed on the investigation.But police have not officially named Kelley as the shooter. They described the gunman as a white man in his 20s. Authorities have not said what the motive was.Kelley was a member of the US Air Force and served at Holloman Air Force Base in New Mexico from 2010 until his discharge, according to Air Force spokeswoman Ann Stefanek.He was court-martialed in 2012 for assault on his spouse and assault on their child, according to Stefanek. He served a year in confinement, received a bad conduct discharge and had his rank reduced, she said.In April 2016, Kelley purchased the Ruger AR-556 rifle he allegedly used in the shooting from a store in San Antonio, Texas, a law enforcement official said. There was no disqualifying information in the background check conducted as required for the purchase, a law enforcement official told CNN.At one point, the shooter tried to get a license to carry a gun in Texas but was denied by the state, Abbott said, citing the director of Texas' Department of Public Safety."So how was it that he was able to get a gun? By all the facts that we seem to know, he was not supposed to have access to a gun," Abbott said. "So how did this happen?"How the attack unfoldedThe gunman was first spotted at a Valero gas station across the street from the church at about 11:20 a.m. (12:20 p.m. ET).He drove across the street, got out and began firing even before he entered the church, Martin said.David Flores told CNN that his father saw the shooter."My dad saw the gunman run into the church building and then he heard shots and saw people running," Flores told CNN. "People covered in blood and screaming. It was pandemonium everywhere."As the shooter left the church, a local resident used his own rifle to engage him, Martin said. The gunman dropped his weapon and fled.Johnnie Langendorff said he was driving to his girlfriend's house when he saw the shootout between the shooter and the armed resident.The gunman took off in a Ford Explorer, Langendorff told CNN affiliate KSAT.The resident "briefed me quickly on what had just happened and said we had to get him, and so that's what I did," Langendorff said.They gave chase in his truck and called police. As they sped after him, Langendorff said, the shooter "eventually lost control on his own and went off into the ditch" in neighboring Guadalupe County."The gentleman that was with me got out and rested his rifle on my hood and kept it aimed at him [shooter], telling him to get out. There was no movement, there was none of that. I just know his brake lights were going on and off, so he might've been unconscious from the crash or something like that. I'm not sure."Law enforcement later found the suspect dead of a gunshot wound inside his vehicle.A law enforcement official briefed on the investigation said multiple weapons were found in the shooter's car. The FBI and the Bureau of Alcohol, Tobacco, Firearms and Explosives are involved in the investigation.The victims and griefHours after the shooting, residents of Sutherland Springs hugged one another, held candles and sang hymns in a vigil Sunday night. Abbott attended the event, in which faith leaders offered words of solace and prayers.Sutherland Springs is the kind of place where "everybody knows everybody," said Gloria Rodriguez Ximenez, who attended the vigil."This is a small, Christian town, a very small community," she said. "Everybody's united. Everybody's so close to everybody."She knows the First Baptist Church's pastor and his family, including their daughter who died."I can feel the pain everybody's going through. There's so much hurt for a small town," Ximenez said.Others echoed the feeling of shock and heartache."My heart is broken," Wilson County Commissioner Albert Gamez Jr. told CNN. "We never think where it can happen, and it does happen. It doesn't matter where you're at. In a small community, real quiet and everything, and look at this."Twenty-three people died inside the church, which has a small sanctuary with wooden pews and red carpeting. Two died outside the church, and one at the hospital.The wounded are being treated at three hospitals including the Connally Memorial Medical Center in Floresville, University Hospital and Brooke Army Medical Center in San Antonio.The-CNN-Wire 6515
