一 | 为丰富辖区群众暑期文化生活，传承杭州本土方言文脉，打通新老杭州人沟通壁垒，近日，凯旋街道南肖埠社区联合街道社区学校、凯西社区共同开展“杭州话 话杭州”趣味杭语公益体验课。 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.。本次公益课堂打破单一对象教学模式，面向辖区全人群，分层定制教学内容，兼顾文化传承与生活实用需求。课堂依托辖区本土老年志愿讲师、上城区社区学院专职教师开展教学，结合街道自主研发《杭州话 话杭州》读本，以趣味化方式授课。针对青少年，通过杭语童谣传唱、本土俗语讲解、宋韵民俗小故事分享、情景小游戏等互动形式，引导青少年学习方言，主动开口说方言。不少外来务工人员的子女是第一次系统接触杭州话，学习兴趣盎然，11岁的桂诗然同学老家在江西，家中无人通晓杭语，一堂课下来便收获满满，打算回家用刚学会的方言和身边长辈交流，希望更快融入本地生活。课堂同时专门面向外卖骑手、快递员、网约车司机、保洁、安保、家政服务、直播从业者等新就业群体，开设实用方言教学板块，聚焦买菜问诊、邻里寒暄、日常办事等高频生活场景，传授简单易懂的日常杭语。不少外卖小哥表示，日常跑单多使用普通话沟通，学会几句本地老话，既能拉近和居民之间的距离，也让自己在这座城市多了一份归属感。凯旋街道社区学校负责人倪艾彤老师表示，方言承载着一座城市鲜活的历史记忆，《杭州话 话杭州》公益课堂以轻松有趣的教学形式适配不同年龄段学习者，既能让少年儿童从小根植本土文化情怀，也能帮助新杭州人读懂杭州、融入社区。近年来，凯旋街道持续深耕本土方言普及工作，常态化推出杭语公益课堂、祖孙研学沙龙等活动，累计开课57课时，惠及群众1720余人次。街道相关负责人介绍，公益课堂将继续免费对外开放，后续将持续优化杭语课堂课程体系，根据少年儿童、本地老人、新杭州人的不同需求差异化设置课程；同时不断充实方言学习读本，开发本土方言特色文创产品。让老居民留住乡音，新市民读懂杭州文脉，以乡音凝聚邻里温情，构建包容共融的幸福社区。
