防范勒索软件病毒攻击的方法在这里
近期国内多所院校出现勒索软件感染情况,磁盘文件会被病毒加密,加密使用了高强度的加密算法对难以破解,被攻击者除了支付高额赎金外,往往没有其他办法解密文件,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。

在此提醒广大校园网用户:
1、为计算机安装最新的安全补丁,微软已发布补丁MS17-010修复了“永恒之蓝”攻击的系统漏洞,请尽快安装此安全补丁,网址为https://technet.microsoft.com/zh-cn/library/security/MS17-010。
2、关闭445、135、137、138、139端口,关闭网络共享。
3、强化网络安全意识:不明链接不要点击,不明文件不要下载,不明邮件不要打开。??
