[建议措施:]

1.目前微软官方已针对此漏洞释出更新程式,请各机关可联络系统维护厂商或参考以下连结进行更新:

https://msrc.microsoft.com/update-guide/vulnerability/CVE-2022-30190

2.若无法进行更新,可参考微软官方网站采取下列缓解措施,以暂时关闭微软支援诊断工具之URL协定:

    (1)以系统管理员身分开启「命令提示字符」视窗

    (2)执行「reg export HKEY_CLASSES_ROOTms-msdt filename」指令进行机码备份

    (3)执行指令「reg delete HKEY_CLASSES_ROOTms-msdt /f」

    (4)后续安装修补程式后,若要还原机码,请执行「reg import filename」

3.请更新电脑防毒软件病毒码。

4.请留意可疑电子邮件,注意邮件来源正确性,勿随意点击信件连结或开启附件。

5.请加强内部宣导,提升人员资安意识,以防范骇客利用电子邮件进行社交工程攻击。
