今天上班先干啥?开机前先断网 避免感染勒索病毒

今天上班第一件事干啥?

别急着打开电脑,先断网!

省网络安全部门:为避免一开机就被感染勒索病毒

□记者 沈丽焕

本报讯 5月14日,“网信海南”微信公众号发布一篇名为《速看!海南省网络安全部门提示:周一上班先拔网线再开电脑》的文章,文中提到近日WannaCry勒索病毒爆发,为了避免周一上班后刚开机就被感染病毒,导致硬盘所有文件被恶意加密,请在开机前先断网,然后咨询本单位网络安全管理员,索取windows补丁安装光盘。

文中称,凡是开机发现电脑已经中病毒的,文件被加密的,禁止接入网络,随后使用光盘安装windows补丁,用不同介质(光盘等)备份电脑里的重要文件,确认445端口关闭,并确认光盘补丁已经安装完毕后,再联网检查更新打补丁。这几天微软补丁更新服务器访问流量太大,连接速度很慢,请大家多试几次。

文中还提醒,使用windows操作系统的主机都有可能被感染,尤其是各单位的“教育网”“内网”“专网”和“局域网”,网内主机长期怠于更新补丁,所以更易被病毒感染。请各单位网络安全管理员按照以上要求通知单位所有人员,避免周一出现一波电脑瘫痪高峰。同时立即关闭各服务器和网络设备上的445等危险端口,然后再去处理个人用户,防止病毒通过服务器和网络设备大范围传播,避免用户装新系统又被感染。如果是内网不方便下载和打补丁,请及时联系当地网络安全厂商,各安全厂商应急小组会安排人员提供现场服务。同时也希望各网络安全公司及时发布公告,提醒用户不要使用来路不明的补丁包和解密软件,严防有黑客制作夹带木马病毒的补丁包和解密软件传播。
