中新社北京7月21日电 美国尤金消息：2022年世界田径锦标赛当地时间20日在美国俄勒冈州尤金市继续进行。
B | 中国选手冯彬第一次投掷就投出69米12的成绩，夺得女子铁饼冠军，这是中国队在本届世锦赛上获得的第二枚金牌。东京奥运会女子标枪冠军刘诗颖资格赛第一次投掷就超过及格线，轻松晋级决赛。 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.。女子投掷是中国队传统优势项目，中国队在东京奥运会上获得的两枚金牌均来自于女子投掷。本届世锦赛，巩立姣已在女子铅球上收获一枚银牌。
C | 本届世锦赛冯彬表现抢眼，资格赛她就一投过关，超过64米及格线直接晋级。决赛第一投冯彬就投出了69米12的好成绩，同时创造了个人职业生涯最好成绩。
D | 其他选手六次投掷都没能超越这一成绩，包括东京奥运会冠军、美国选手奥尔曼以及两届奥运会、两届世锦赛冠军克罗地亚选手佩尔科维奇，最终冯彬夺得冠军。佩尔科维奇和奥尔曼分别以68米45和68米30获得二、三名。去年东京奥运会，冯彬状态不佳未能晋级决赛，在世锦赛赛场她最好成绩是上届多哈世锦赛的第五名。
E | 本赛季冯彬水平有很大提升，今年4月将职业生涯最好成绩提升至66米00，此次夺冠的成绩69米12也超过了奥尔曼东京奥运会夺冠成绩68米98。女子标枪资格赛，东京奥运会冠军刘诗颖B组第三位出场，她第一枪就投出了63米86的成绩，远超62米50的及格线，从而轻松晋级。上届多哈世锦赛刘诗颖获得银牌，她表示很久没有参加比赛，这次世锦赛激动又紧张，希望能够进一步突破自己。第四次征战世锦赛的老将吕会会在资格赛A组三投均未超过60米，最终成绩是57米59，排名27位参赛选手中的第16位，从而无缘决赛。这是她第一次未能晋级世锦赛决赛，前三次世锦赛她获得一银两铜。目前为止，中国队在本届世锦赛上已夺得2金1银1铜，暂居奖牌榜第三位。(完)
