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.

As students begin to head back to the classroom – either virtually or in person – this month begins the most uncertain school year in recent memory.While some public health experts have expressed apprehension about reopening schools, President Donald Trump gave a full-throated defense for bringing back students into classroom full time this fall. Trump hosted a group of educators and school administrators at the White House on Wednesday.Amid Trump’s effort to reopen schools, the CDC released updated guidance last month that emphasizes reopening schools. The new guidance contradicts previous guidance, which recommended closing schools during periods of substantial community transmission.The updated guidance said that extended school closures are harmful to children and can lead to severe learning loss, and the need for in-person instruction is particularly important for students with heightened behavioral needs.During an event with educators on Wednesday, Trump said not only should students return to the classroom, but he decried hybrid schedules, which incorporates a blend of in-person and virtual learning. Proponents of hybrid schedules say that they allow for students to have some in-person learning while opening more classroom space for social distancing.But the president is not a fan.“The concept of every other day seems a little ridiculous, right?” Trump said. “If you are going to do it, you do it. If you are not going to do it, the concept of going back even from a management standpoint from the school, every other day seems very strange.”Trump once again called on Congress to pass 5 billion in education funding, which House Democrats have also pushed for as part of a broader stimulus plan. While Treasury Secretary Steven Mnuchin said the White House is open to doing a piecemeal approach to a stimulus package, House Democrats have pushed for an all-encompassing bill.Some of the funding for schools could be used to help districts with additional costs associated with mitigating the risk of the virus.Trump said that the funds should follow the students. He has previously said that if schools opt for online learning, they should not receive federal funds.“If the school is closed, you know, why are we paying if a school is closed?” Trump asked. “Why are we paying the school if it is closed? I would rather give it to the student, the parents, and you do your own thing, and to me it makes a lot of sense.”While Trump is eager for a full return to school, there are several cautionary anecdotes from several districts that opened earlier this month.Most notably, the Cherokee School District in Georgia reported on Tuesday 59 students and employees tested positive for the coronavirus following its reopening. The district is now asking 925 employees and students to quarantine for two weeks. The district’s Etowah High School will remain closed until August 31 due to the outbreak. 2935

ATLANTA (AP) — Early in-person voting began Monday in Georgia for the state's two U.S. Senate runoffs.The early voting period runs as late as Dec. 31 in some counties.It could determine the outcome of the races between Republican U.S. Sens. David Perdue and Kelly Loeffler and Democratic challengers Jon Ossoff and Raphael Warnock.A majority of votes before the Nov. 3 general election were cast in person during early voting.The period could be even more important during the runoffs because of the shortened period for voters to request and return ballots by mail.More than 125,000 people cast ballots in October on the first day of early voting. Lines were long then and could be long again Monday. 709

As our country works to rebound, we're helping you manage the pressure as the pandemic is shifting caregiving responsibilities.More millennials are taking on this responsibility now. They're becoming a greater percentage of what's known as the "sandwich generation." Those are people who are caring for both their own kids and their aging parents.New numbers from insurance company New York Life show a third of millennials are doing this now.“We're not replacing the typical 49-year-old woman who's the family caregiver. She's still doing it, but the need is so great that more and more young people are called into the role as well and that's going to continue well after the COVID pandemic,” said John Schall, CEO of the Caregiver Action Network.Nearly half of the so-called "sandwich generation" expect to be a caregiver in some capacity for six or more years.The added financial strain is one concern. Schall says out of pocket expenses can be about a thousand dollars a month.More than half of these caregivers say they're spending more than usual per month to care for others as a result of the pandemic. That means they're contributing less to their savings and their retirement.There's also the concern about the mental toll.“With millennial generation caregivers, you may not be thinking about depression, you know, at that age, but the fact is the sheer stress of the role of being a family caregiver increases that risk of depression twice as often,” said Schall.If you are feeling overwhelmed, the caregiver help desk from the Caregiver Action Network can be one place to turn. You can call them free of charge at 855-227-3640. 1648
