Researcher: National Emergency Alert System is Easy To Exploit_我的网站

一 |     近日，黄龙体育中心世纪星华洋冰上运动中心正式开门迎客。冰场位于西湖区体中三路1号黄龙体育中心，乘地铁3号线或10号线到“黄龙体育中心”站，从F口出站即达。这个“家门口的冰上世界”，拥有1800平方米的冰面，达到奥运标准，旁边是3000座分层固定、无遮挡的专业看台，可承接花样滑冰、冰球、短道速滑三类国家级赛事。    The Department of Homeland Security is telling state and local governments to update software and beef up security around devices connected to the nationwide Emergency Alert System (EAS). The recommendation comes days after security researcher Ken Pyle revealed vulnerabilities in devices used by officials to encode EAS alerts.,Pyle told KerbsOnSecurity that he first discovered the vulnerabilities in 2019 after buying old EAS equipment on eBay. He quickly found the vulnerabilities and alerted the FBI, DHS, and the manufacturer of the devices. Pyle decided to give the manufacturer and government time to address the issue before going public.,DHS Inspector General Overseeing Jan.6 Secret Service Probe Previously Misled Investigators: Report4 August, 12:27 GMT,He started to worry after the Jan 6, 2021 riot at the US Capitol, fearing that the vulnerabilities could be used “to start a civil war.”,That is because despite a patch being issued in 2019, many of the devices have not been updated either because they are too old for the new firmware or because of simple neglect by the operators. Pyle also says that many operators do not perform basic security measures recommended by the manufacturer, like changing the default password and putting the devices behind a firewall.,This is a problem because of the way EAS messages are distributed. There is no central authority and the process is automated in most cases. This means that someone could issue an alert locally and as long as it is accepted as a real EAS alert, it could spread nationwide.,“These devices are designed such that someone locally can issue an alert, but there’s no central control over whether I am the one person who can send or whatever,” Pyle told KerbsOnSecurity. “If you are a local operator, you can send out nationwide alerts. That’s how easy it is to do this.”,One device obtained by Pyle was a non-functional EAS device, purchased from an electronics recycling company. While the device no longer operated, the person who discarded it and the recycling company neglected to wipe the hard drive, giving Pyle access to cryptographic keys allowing him to broadcast messages on Comcast’s network, the third largest cable company in the US.,Comcast told KerbsOnSecurity in a statement that the EAS was lost by a third-party shipper and that the keys and credentials found on the device will no longer work on their system. They also thanked Pyle for his research and for informing them about the issue.,EAS vulnerabilities have been exploited in the past. In 2013, someone hacked the EAS networks in Great Falls, Montana, and Marquette, Michigan, using their access to issue an alert saying that zombies are rising from their graves. That same prank was repeated in Indiana in 2017. There have been other incidents, though they did not include zombies.。作为目前浙江省规模最大且具备国家级花滑赛事全流程承办资质的专业室内冰场，场馆目前主推两个项目：花样滑冰和冰球。开业前，中心已经办过中国花样滑冰俱乐部联赛和中国青少年冰球联赛，算是“先练兵，再迎客”。花样滑冰教学，由国际级教练芦美嘉、金牌教练李香凝等资深团队领衔；冰球项目，请来了俄罗斯籍教练。为什么把冰场落在黄龙？场馆负责人说，第一，黄龙有标准冰面和带看台的附属设施，硬件够硬；第二，这里是浙江传统的体育培训集聚区，运动氛围很浓，客流基础也很稳。
