抓到了!華為旗下海思晶片有後門 恐加深各國對中國產品疑慮

中國企業華為的5G設備正因安全問題被世界各國放大檢視,如今又爆出華為旗下的海思(
HiSilicon)晶片被發現有後門,可讓有心人藉此存取使用該晶片的網路攝影機或閉路電
視所拍到的影像,這項消息恐將加深各國對華為的疑慮。
海思半導體為華為集團旗下的晶片設計公司,產品被應用在數百萬的連網裝置上,包括監
視器、數位錄影機(DVR)及網路硬碟錄影機(NVR)等。
綜合《The Register》、《Extreme Tech》等多個國外科技網站報導,一名俄羅斯安全研
究人員Vladislav Yarmak發現,海思SoC晶片系統韌體有個遠距除錯和管理工具,可存取
同個網路的攝影機和閉路電視等產品的內容。只要有人連接特定端口TCP 9530,並開啟
Telnet守護程序,就可以憑簡單的root帳號和固定密碼登入(而且所有裝置上的密碼都一
樣),進而擁有最高權限,可隨意存取內容或控制該裝置。
Vladislav Yarmak認為,這項漏洞是刻意留存的後門,至少存在於使用 hi3518 SoC 晶片
的大量網路攝影機和閉路電視產品,估計受影響的連網裝置有數十萬到數百萬不等,用戶
恐怕無法期待海思修補這項漏洞,只能限制裝置本身的網路存取能力,或直接改用其它未
含漏洞的產品,才能確保內部資料的安全。
自美中貿易戰以來,美國一直向歐洲各國喊話,強調採用中國企業華為的產品將對國安造
成風險。雖然有些國家始終秉持自己的立場,未對美國的說法全盤買單,但這項消息一出
,無疑重挫華為的信用,且可能會影響更多尚未表態是否採用華為產品的國家的最後決定
。
