足不出户 走遍全世界
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.。 为工业领域绿色低碳转型探索可复制、可推广的实践路径99家企业将建设零碳工厂日报讯（记者米彦泽）8月13日，省工信厅、省发展改革委、省生态环境厅、省国资委联合印发通知，公布了2026年度省零碳工厂建设名单，兰升生物科技集团股份有限公司等99家企业入选。“双碳”目标持续推进下，零碳工厂日渐成为制造业绿色转型风向标。零碳工厂建设是指通过技术创新、结构调整和管理优化等减排措施，实现边界内二氧化碳排放的持续降低、逐步趋向于近零的过程。省工信厅相关负责人介绍，零碳工厂不是绝对的“零”二氧化碳排放，而是在当前技术经济条件允许下，实现应减尽减并持续改进提升，保持工厂二氧化碳排放最低水平。值得注意的是，零碳工厂建设不是“申报即认定”，也不是“达标即结束”，而是以核心指标为牵引、以建设方案实施为重点、以年度自我评估和进展报送为支撑、以评估验收和持续披露为保障的全过程动态管理机制。位于邢台市宁晋县的天环线缆集团有限公司，是2026年度省零碳工厂建设名单中的一员。作为国家级绿色工厂，天环线缆集团投资491万元通过空压机变频改造、电动叉车替代、光伏并网及太阳能照明推广等措施，年综合能耗显著下降。在天环线缆集团副总经理刘娟生看来，建设零碳工厂，既是响应制造业绿色转型的应有之义，更是应对供应链碳足迹追溯的必然选择。线缆制造核心工序拉丝、退火、挤塑、交联均为高耗能环节，生产工艺成熟但能耗基数大。“2024年我们在厂区安装了2.5兆瓦太阳能光伏板，通过绿电直连满足工厂白天生产用能，目前公司可再生能源使用量占比59.07%。
二 | ”刘娟生介绍，未来两年，他们还将继续建设2兆瓦太阳能光伏+储能电站项目，将绿电使用比例提升至100%。除了能源端使用绿电，天环线缆集团还将继续在设备端发力。目前，该公司已将10台挤塑机的空压机更换为永磁变频螺杆空压机，可降低能耗30%。现在，他们正全面排查在用设备，完成1级能效设备升级替换，从源头降低生产能耗。天环线缆集团正在建设一体化能碳管理平台，对能源消耗和碳排放进行精细化、可视化管理，并为生产管理决策提供数据支持。通过一系列项目实施，该公司单位工业增加值碳排放可从目前的0.34吨二氧化碳/万元降至0吨二氧化碳/万元，进而实现零碳工厂建设目标。对于入选省级零碳工厂建设名单的企业，省将加强跟踪帮扶，指导企业补短板、强弱项，按照建设规划目标有序推进零碳工厂建设。统筹运用好现有政策，支持建设单位规模化实施绿色低碳改造、大规模设备更新等技术改造项目，优先推荐申报“两重”“两新”项目，具备条件的优先推荐申报国家零碳工厂。支持建设单位申请绿色金融融资需求。随着建设工作的深入推进，省将逐步培育形成一批能源结构持续优化、排放水平稳步降低、过程脱碳措施扎实、数据管理规范、带动作用突出的零碳工厂，为工业领域绿色低碳转型探索可复制、可推广的实践路径，为培育绿色低碳新质生产力提供有力支撑。
