[建議措施:]
1.目前微軟官方已針對此漏洞釋出更新程式,請各機關可聯絡系統維護廠商或參考以下連結進行更新:
https://msrc.microsoft.com/update-guide/vulnerability/CVE-2022-30190
2.若無法進行更新,可參考微軟官方網站採取下列緩解措施,以暫時關閉微軟支援診斷工具之URL協定:
(1)以系統管理員身分開啟「命令提示字元」視窗
(2)執行「reg export HKEY_CLASSES_ROOTms-msdt filename」指令進行機碼備份
(3)執行指令「reg delete HKEY_CLASSES_ROOTms-msdt /f」
(4)後續安裝修補程式後,若要還原機碼,請執行「reg import filename」
3.請更新電腦防毒軟體病毒碼。
4.請留意可疑電子郵件,注意郵件來源正確性,勿隨意點擊信件連結或開啟附件。
5.請加強內部宣導,提升人員資安意識,以防範駭客利用電子郵件進行社交工程攻擊。
