SANTA CLARA, Calif. (AP) — Intel has revealed another hardware security flaw that could affects millions of machines around the world.The bug is embedded in the architecture of computer hardware, and it can't be fully fixed."With a large enough data sample, time or control of the target system's behavior," the flaw could enable attackers to see data thought to be off-limits, Bryan Jorgensen, Intel's senior director of product assurance and security, said in a video statement.But Intel said Tuesday there's no evidence of anyone exploiting it outside of a research laboratory. "Doing so successfully in the real world is a complex undertaking," Jorgensen said.It's the latest revelation of a hard-to-fix vulnerability affecting processors that undergird smartphones and personal computers. Two bugs nicknamed Spectre and Meltdown set a panic in the tech industry last year.Intel said it's already addressed the problem in its newest chips after working for months with business partners and independent researchers. It's also released code updates to mitigate the risk in older chips, though it can't be eliminated entirely without switching to newer chips.Major tech companies Google, Apple, Amazon and Microsoft all released advisories Tuesday to instruct users of their devices and software, many of which rely on Intel hardware, on how to mitigate the vulnerabilities.As companies and individual citizens increasingly sign their digital lives over to "the cloud" — an industry term for banks of servers in remote data centers — the digital gates and drawbridges keeping millions of people's data safe have come under increasing scrutiny.In many cases, those barriers are located at the level of central processing unit, or CPU — hardware that has traditionally seen little attention from hackers. But last year the processor industry was shaken by news that Spectre and Meltdown could theoretically enable hackers to leapfrog those hardware barriers and steal some of the most securely held data on the computers involved.Although security experts have debated the seriousness of the flaws, they are onerous and expensive to patch, and new vulnerabilities are discovered regularly.Bogdan Botezatu, director of threat research for security firm Bitdefender, said the latest attack was another reason to question how safe users can really be in the cloud."This is a very, very serious type of attack," Botezatu said. "This makes me personally very, very skeptical about these hardware barriers set in place by CPU vendors."Intel said it discovered the flaw on its own, but credited Bitdefender, several other security firms and academic researchers for notifying the company about the problem.Botezatu said Bitdefender found the flaw because its researchers were increasingly focused on the safety and management of virtual machines, the term for one or more emulated mini-computers that can be spun up inside a larger machine — a key feature of cloud computing. 2976

SEATTLE (AP) — Greyhound, the nation's largest bus company, says it will stop allowing Border Patrol agents without a warrant to board its buses to conduct routine immigration checks. The company announced the change Friday, one week after The Associated Press reported on a leaked Border Patrol memo confirming that agents can't board private buses without the consent of the bus company. Greyhound had previously insisted that even though it didn't like the immigration checks, it had no choice under federal law but to allow them. U.S. Customs and Border Protection, which includes the Border Patrol, did not immediately return a call seeking comment. 662

SAN TAN VALLEY, Ariz. — In-person schooling was supposed to begin Monday for the J. O. Combs School District, but a move by teachers and staff forced the district to cancel school for the day.On Friday, a J. O. Combs Spokesperson said 109 teachers and staff requested not to work on Monday."Due to these insufficient staffing levels, schools will not be able to re-open on Monday as planned. This means that all classes, including virtual learning, will be canceled," wrote J. O. Combs Superintendent Dr. Gregory Wyman in a letter to parents on Friday. "At this time, we do not know the duration of these staff absences, and cannot yet confirm when in-person instruction may resume."A teacher in the district said that one of the reasons teachers decided to call out Monday was that they felt unprepared to teach students virtually and in-person.Teachers are expected to simultaneously instruct students in the classroom and those at home via live stream. One teacher believes they were not adequately prepared to cater to both types of learners, since all of the educators' attention has been on executing online learning."The issue is that [a] teacher would not be able to tend to the online learners that are on Google," said a teacher in the district. "Even in-class learning must be modified for online. So it's a lose-lose for both types of learners."That teacher said only one hour of training was given for the live stream equipment."Some classes have as many as 36 [on] their roster or more. About half are choosing to stay home, so we really need to service our online learners."Aside from the feeling of unpreparedness from teachers, many feel unsafe since benchmarks set by the Arizona Department of Health Services have yet to be met by any of the school districts."My coworkers do not feel safe. Metrics being met is a big deal. We also want to keep at-risk teachers with online kids."The district's Governing Board voted against the superintendent's recommendation to move in-person education to October, and also shot down a motion to forgive a ,000 penalty for teachers, ,500 for administrative staff, who decide to break their contract due to COVID-19.Teachers in the district hope to come to a resolution with the district to continue online-only teaching until health benchmarks are met.On Monday, students of Combs High School are also staging a march in support of teachers who did not call out at 10 a.m.The district says they will monitor the situation and expects to have an update no later than 5:00 p.m. Monday.This story was originally published by Adam Waltz on KNXV in Phoenix. 2619

SEATTLE (AP) — Researchers say a London man appears to be free of the AIDS virus after a stem cell transplant. It's the second such success including "Berlin patient" Timothy Ray Brown.Such transplants are dangerous and have failed in other patients. The new findings were published online Monday by the journal Nature.The London patient has not been identified. He was diagnosed with HIV in 2003. He developed cancer and agreed to a stem cell transplant to treat the cancer in 2016.His doctors found a donor with a gene mutation that confers natural resistance to HIV.The transplant changed the London patient's immune system, giving him the donor's HIV resistance. 674

SAN MARCOS, Calif. (KGTV) — A photo of a Cal State San Marcos graduate is going viral. It shows 29-year-old Erica Alfaro in her cap and gown, standing with her parents, in the middle of a strawberry field in Carlsbad.Her educational journey was anything but easy. “I was a teenage mom,” Alfaro said. She was 15 and pregnant, and became a mother at 16. Alfaro said she dropped out of high school and was stuck in an abusive relationship.“My baby’s father forced me to sleep outside with my baby,” Alfaro said. “That is the night I decided to go back to school.”She left Fresno and returned home to Oceanside. It was then that she remembered a moment from when she was 13-years-old.“My mom took me to work with her in the tomato fields,” Alfaro said. “And I remember she told me, ‘This is our life. The only people who have a good life are the people who have a good education.’”Alfaro was born in Fresno but spent most of her elementary years in Tijuana, Mexico. When she was 13, she and her family moved to Oceanside. Her parents got jobs as farm workers. They never received a formal education. “They don’t know how to read or write,” Alfaro said. All the signs pointed toward her repeating that cycle. But Alfaro was not going to let that happen. “I did it for my son,” she said. Little Luis inspired her to finished high school through homeschool, and enroll in Junior College. The next step was Cal State San Marcos. Statistics show that only 2 percent of teen mothers finish college by the age of 30. But Alfaro pushed forward. “At first I thought I was being unrealistic, but I just started to keep going,” she said. But in 2012, Alfaro got a diagnosis that changed her life once again. “My son was diagnosed with cerebral palsy,” she said. The depression overcame her, and she dropped out of college. But again, she remembered that day at the tomato fields. “I had so many excuses to give up. But giving up was never an option,” Alfaro said. Five years later, she earned her bachelor's degree at CSU San Marcos. On Sunday, as if she has not accomplished enough, Alfaro will receive a Masters in Education from San Diego State University. She hopes to inspire students and her now 13-year-old son, to never give up. “My son represents a new generation,” Alfaro said. “He will have a better future. He will have more opportunities, and I will be there to tell him that it is possible. That he belongs. All those things I never heard myself.” 2454
