各位老师、同学:

近日,国内很多学校电脑感染勒索病毒,重要文件被加密,类似下图所示。

此类勒索病毒利用了基于445端口传播扩散的SMB漏洞,一旦中毒,恢复文件比较困难,经查,我室许多开放了445端口,为此,建议师生们做预防处理。

 

一、此次利用的SMB漏洞影响以下未自动更新的操作系统:

Windows XPWindows 2000Windows 2003

Windows VistaWindows Server 2008Windows Server 2008 R2 

Windows 7Windows 8Windows 10

Windows Server 2012Windows Server 2012 R2Windows Server 2016

 

二、个人预防措施:

1.未升级操作系统的处理方式(临时缓解):

启用并打开“Windows防火墙”,进入“高级设置”,在入站规则里禁用“文件和打印机共享”相关规则。

2.升级操作系统的处理方式(推荐):

建议广大师生使用自动更新升级到Windows的最新版本。

3. 勤做重要文件非本地备份(推荐);

4.不要打开来历不明或者可疑的电子邮件和附件(推荐)。

 

三、未自动升级的电脑建议安装微软MS17-010补丁
