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

追梦赤子心

A |     近日,工业和信息化部发布2024年先进制造业集群竞赛胜出名单,共有35个集群上榜,其中3个来自辽宁,分别为大盘绿色石化集群、沈大工业母机集群、沈阳航空集群。    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.。加之此前已获此殊荣的沈阳机器人及智能制造产业集群,目前,在已经选出的80个国家级集群中,我省共有4个入围,总数居全国第六位、东北地区首位。           近年来,我省积极打造4个万亿级产业基地、22个重点产业集群,有力促进了产业规模快速壮大、产业质效加快提升、科技创新与产业创新深度融合。           本次入选的3个先进制造业集群各具特色。

B | 其中,大盘绿色石化集群以大连市和盘锦市为主要载体,拥有国内最完整的石化全产业链条,是我国最重要的原油、化工产品加工,进出口贸易和储运以及航运中心。其原油生产能力合计超过2000万吨,居全国前列,是国内同时具备油田、管输俄油、海上进口油等多源头原油加工能力的集群。           沈大工业母机集群以沈阳市、大连市为核心,以守护产业安全战略需求为引领,以突破高端数控机床、关键功能部件等“卡脖子”技术为主攻方向。该集群由7位院士领衔,汇聚中国科学院沈阳自动化研究所、金属研究所及中国机械总院等单位的40余位国家级专家,建有高档数控国家工程研究中心等省级以上创新载体60个。           沈阳航空集群拥有沈飞、黎明、沈飞民机、中国航发燃机等知名龙头企业以及沈阳航空航天大学等重要研发单位,产品涵盖了航空发动机、燃气轮机、民机大部件、通航和无人机等产品,已构建形成产品种类齐全、供应链体系健全、产业生态完整的航空产业集群。                    责任编辑:李丹。
