郑钦文遭逆转无缘四强，4个残酷事实球迷不得不接受_我的网站
一 | 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.。
2026年7月17日晚的雅典，WTA250公开赛女单1/4决赛打到第一盘第3局结束的时候，没人觉得郑钦文会输。3-0，她的开局。两个发球局全保，还破了对面赛会三号种子克雷吉茨科娃的发球局，收那局的时候飙了个ACE，球砸在底线内沿，弹起来都没过网带。
二 | 郑蹲下来系鞋带的时候，把拍柄往鞋底敲了两下，蹭掉点红土灰，抬头看了眼对面的克雷，对方正弯腰系护腕。对面是拿过两座大满贯冠军的捷克人，世界排名比郑钦文高89位，之前两次交手郑全胜，最近一次是去年年终总决赛半决赛，也是直落两盘赢的。接下来两盘的剧本，连写网文的都不敢这么编：先领先的永远是郑钦文，先被翻的也永远是郑钦文，最后总比分0-2（4-6、4-6），无缘四强。
三 | 第5局郑钦文本来30-0领先，克雷忽然换了打法，反手削了个带侧旋的短球，落点卡在发球线和单打边线的夹角，郑冲上去够，拍面压早了半帧，球飞了。
四 | 下一分克雷又削，这次更浅，郑的脚步慢了半拍，挑高球被对面直接扣在场地空当，30-30。再下一分郑的一发偏出边线，双误，破发点。二发软，克雷正手抽直线，破发。3-2，刚才还攥在手里的优势，两分钟没了。第7局更顺：郑又是30-0开局，又是被连续追分，最后一分抛球偏高，发球直接下网，再见双误，3-5。
五 | 后面她保了非保不可的第8局，没能再破回来，第一盘4-6。这盘郑的一发成功率只有39%，全场打完也才48%，对面克雷是65.2%。39%是什么概念？ WTA巡回赛里球员的一发成功率基准线是55%，低于45%就已经要靠二发硬扛了，39%相当于每两个发球局就要丢一个，要不是克雷今天非受迫失误也比平时多，这盘根本走不到4-6。第二盘开局又是郑先破发，2-0。郑2-0领先的时候，克雷叫了次短暂停，回来之后就开始把节奏往慢了拖，不再跟她对拉平击，转而用反手切削长短交替，偶尔放个短球逼郑上网。郑的平击打法本来就吃节奏，对面一慢一快变着来，她的相持球越打越急，给的失误越来越多。中段克雷回破把比分扳到2-2，后来抓了郑又一次发球波动，把比分拉到5-3，郑保了一局追到4-5，没能力再破回来，第二盘又4-6。这场之前郑对克雷的两场球，2023郑州WTA500决赛，2024年终总决赛半决赛，都是郑赢的，年终那场她还打了一个"谢谢，再见"的经典镜头。这次输，真不是说克雷超常发挥，是郑的几个老问题又冒了。慢旋切削的球，她现在确实应对得不好。
六 | 克雷本来就是双打起家的，反手切削的变化是刻在肌肉记忆里的，郑的站位习惯是等球弹到腰部高度再发力，这种飘着的削球弹起来矮，还往场外拐，她要么抢点抢不到，要么拍面压不住，起球质量一差，对面就有机会抡制胜分。
七 | 今年法网她也是被类似的"月亮球"磨走的，这不是第一回了。一发的问题从她复出开始就没解决，这三场一发成功率是逐场往下掉的，这场首盘39%，比前两场还低。关键分的发球也飘，两盘的转折点都是她自己30-0领先的时候发的那两个局，双误都扎在破发点上，不是力量不够，是抛球的时候脚有点乱，急着要拿下那一局，手先紧了。
八 | 郑现在的即时排名是121位，克雷是32位，差89位，克雷拿过2021法网和2024温网的冠军，落后时候的抗压是真稳，你给她缝儿她就敢钻，不像排名低的选手领先了容易松。这场是郑钦文13个月以来的第一个巡回赛八强，之前法网温网都是一轮游，半年换了三次教练，状态本来就在恢复期，能打到八强其实不算差，但输的这种方式，确实憋。赛后技术统计摆着：郑钦文的制胜分25-11领先克雷，但非受迫失误41-32也多了9个，破发点转化率只有33%，克雷是50%。说白了就是她自己把机会漏出去的，不是被打花的。
九 | 这次比赛拿了54分，郑的排名只能回到120左右，本来想靠雅典站抢分直接进美网正赛的，现在没成，接下来要去打华盛顿500，再之后是美网资格赛。散场的时候有球迷举的牌子写着"下次把3-0守住"，风一吹晃了晃，也不知道下次碰到克雷，她能不能把拍面上的灰蹭掉。
