微軟怪罪美政府

「想哭」據信是美國國家安全局（NSA）遭竊的網路工具，主要是利用微軟較舊版本操作系統的安全漏洞。微軟早於3月發布修補程式，但許多用戶未更新，淪為攻擊目標。美國總統川普已下令國家安全顧問博塞特負責遏止災情擴大。
微軟總裁史密斯將此怪罪美國政府，指責中央情報局（CIA）和NSA不向軟體商通報安全漏洞，反而儲存一些會被駭客利用的軟體密碼。「這次攻擊再次證明為何政府囤積安全漏洞會變成問題」，「全球政府應把這次攻擊視為警鐘」。 

如何避免遭勒索病毒攻擊

1.使用隨身碟、外接硬碟或雲端空間，將重要資料備份
2.關閉Windows系統的445通訊埠，關閉網路共用資料夾
3.不要點擊來路不明的網站、檔案和郵件
4.安裝微軟Eternal Blue安全性修補程式
5.不要繳納贖金，駭客得知你有能力付贖金，再被勒索可能性很高，也不保證駭客會履約
6.開啟Windows Update，隨時升級系統，修補漏洞
7.剛跳出中毒畫面，資料逐漸被加密，建議立即切斷網路並強制關機
8.檔案已全數遭駭客加密完成，可考慮嘗試防毒軟體公司釋出的解密工具，千萬不要開啟防毒軟體硬碰硬，以免檔案即使解密也無法再開啟
9.若採用上述方式解密仍失敗，務必留下硬碟，或直接找顆硬碟對拷
