校园网用户：

2017年5月12日20时左右，全球爆发大规模勒索软件感染事件。据公安部通报，教育行业已有数万台终端遭遇了攻击，情况严重。

磁盘文件会被病毒加密为.onion后缀，只有支付高额赎金才能解密恢复文件，对学习资料和个人数据造成严重损失。

根据网络安全机构通报，这是不法分子利用NSA黑客武器库泄漏的“永恒之蓝”发起的病毒攻击事件。“永恒之蓝”会扫描开放445文件共享端口的Windows机器，无需用户任何操作，只要开机上网，不法分子就能在电脑和服务器中植入勒索软件、远程控制木马、虚拟货币挖矿机等恶意程序。

由于以前国内多次爆发利用445端口传播的蠕虫，运营商对个人用户已封掉445端口，但是教育网并没有此限制，仍然存在大量暴露445端口的机器。据有关机构统计，目前国内平均每天有5000多台机器遭到NSA“永恒之蓝”黑客武器的远程攻击，教育网就是受攻击的重灾区！

由于我校提前防御得当，目前网络信息中心还没有接到我校ONION勒索软件病毒感染和爆发的案例。

在此提醒广大师生：目前微软已发布补丁MS17-010修复了“永恒之蓝”攻击的系统漏洞，请广大师生尽快为电脑安装此补丁，并关闭文件共享功能，可以避免遭到勒索软件等病毒的侵害。
