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

A |     在当今国际关系的复杂舞台上，巴基斯坦和伊朗这两个国家的互动正成为了全球关注的焦点。

B | 近期，巴基斯坦陆军参谋长穆尼尔的德黑兰之行不仅是一个偶然的外交事件，更是背后更为深厚的地缘政治博弈的缩影。    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.。    首先，此次穆尼尔的访问并非是一场简单的外交交流，而是在美国总统特朗普的“指派”下进行的调解行动。

C | 据美媒披露，特朗普在上周末与穆尼尔通话后，即希望他能继续作为美国与伊朗之间的沟通桥梁。显然，在当前紧张局势下，特朗普对伊朗问题的处理显得格外急迫。然而，伊朗方面对此态度冷淡。议会议长卡利巴夫直言不讳，认为双方信任已遭撕毁，而恢复谈判的先决条件是美国政府必须重新赢得伊朗的信任。        此时的巴基斯坦可谓身处一个微妙的位置。作为传统上与美国保持密切关系的盟友，巴基斯坦不仅要尽力维护与美国的联系，还需应对日益复杂的地区安全局势。穆尼尔的德黑兰之行，表面上看似在为特朗普的外交努力增添助力，但实际上也反映出巴基斯坦自身的战略考量。

D | 在防务层面，巴基斯坦与土耳其和沙特结成联盟，特别是在中东的局势波动中，他们共同的防御协议却未必能迅速落实，这让巴基斯坦不得不谨慎行事，以免与伊朗彻底决裂。    在穆尼尔到访期间，特朗普政府正在积极筹备新一轮的经济制裁，这种两手策略看似矛盾，但也是美国在面对伊朗强硬姿态时无奈的表现。

E | 贝森特财长的言辞表明，美国正试图通过极限施压来迫使伊朗接受既定条款。然而，历史经验告诉我们，仅凭制裁手段很难撼动一个经过长期制裁考验的国家。正如伊朗高层所指出的那样，当前对于美国的态度已趋于对抗，尤其是在特朗普政府频频展示出退意的背景下，伊朗或许更加坚定了不妥协的立场。        进入2026年，全球政治环境愈发复杂，成为地区争端的中心的中东，尤其是伊朗、沙特等国之间的博弈，以及外部势力的介入，形成了一个难以绝望的漩涡。

F | 美国虽然在国际舞台上仍是个强权，但其能否有效施加压力、促进和谈，屡屡受到挑战。对于伊朗而言，制裁的冲击虽然不能忽视，但其长期以来构建的生存法则和韧性，使其在面对压力时并不轻易妥协。    再来看巴基斯坦在国际局势中的角色，它不仅是美国的盟友，同时在与邻国的关系中也必须保持灵活。巴基斯坦与伊朗的关系始终充满变数，近年来随着伊朗与西方关系的紧张，巴基斯坦能够扮演“和事佬”的角色，或许是出于对地区稳定的追求。虽然在表面上，巴基斯坦和伊朗的军事合作尚未实质化，但这一隐秘的外交努力传递出它们之间仍存有沟通的可能性。        展望未来，巴基斯坦在处理与伊朗关系时需要找到合适的平衡点。倘若不能妥善应对与伊朗的紧张关系，巴基斯坦可能在地区权力斗争中被迫选择立场，这并非它所期望的局面。同时，美国的策略如果未能见效，特朗普及其政府将不得不重新审视对伊政策，寻求更多的外交渠道与谈判机会，而不仅仅是倚靠制裁。    总之，如今的中东局势风云变幻，巴基斯坦、伊朗与美国之间的互动不仅关乎各自的国家利益，也将深远影响整个地区的安全与稳定。对于全球观察者而言，了解这些复杂关系背后的动力与逻辑，及时把握局势的动态变化，显得尤为重要。返回，查看更多。
