Google Cloud 旗下的資安團隊 Cybersecurity Action Team,在近期發表的 2023 年資安趨勢報告「Threat Horizons: August 2023 Threat Horizons Report」中指出,愈來愈多駭侵者利用「版本置換」(Versioning)的方式,通過 Google Play Store 的上架前檢查流程並成功上架。
在這份報告中,Google 先列出 Google Cloud 2023 年第一季統計所得的雲端服務攻擊原因,其中未設定密碼或密碼不夠強,其佔比高達 54.8%;其他原因還包括資安設定錯誤(19%)、敏感 UI 或 API 曝光(11.9%)、登入資訊遭竊(7.1%)、使用軟體存有漏洞(2.4%)等。
此外,在這份報告中,Google Cloud 資安團隊也解釋 Google Play Store 中會有惡意軟體上架的原因。駭侵者多半利用一種稱為「版本置換」(Versioning)的手法,先把不含任何惡意軟體的最初版本上架到 Google Play Store 中,以通過各種資安檢查流程,成功上架到 Googel Play Store 上;待使用者下載安裝後,再以版本更新的機制,將惡意軟體酬載自第三方伺服器安裝到使用者已安裝在裝置中的 App 內。
雖然 Google 在其 Play Store 使用規範中明白規定,禁止任何軟體使用 Google Play 官方提供的更新機制以外的方式,對已下載安裝的軟體進行更新、變更或替換,也禁止自第三方伺服器下載任何可執行檔,例如 dex、JAR 等檔案,但顯然有不少 App 並未遵守這個禁令,仍會在使用者下載完沒有問題的版本後,再透過第三方伺服器安裝惡意軟體程式碼酬載。
建議 Android 使用者即使在官方 Google Play Store 中下載安裝軟體,也應在下載前先檢視其他使用者的意見回饋,如有大量負評則應避免下載。
德國柏林科技大學(Technical University of Berlin)的資安研究人員,日前表研究報告,指出研究人員發展出一種破解 Tesla 車內資訊娛樂系統(Infotainment systems)的方法,可以破解 Telsa 對某些付費專屬軟體的限制。
Tesla 車內配備的資訊娛樂系統,採用由晶片設計大廠 AMD 生產製造的 AMD Zen 1 CPU 作為主要處理器;研究人員利用逆向工程技術,追蹤該系統的啟動流程,並且找到該晶片系統的「越獄」(jailbreak)方法。
研究團隊表示,在越獄後,研究人員即可自由啟用通常必須付費才能使用的 Tesla 車內進階功能,例如電熱椅或更凌厲的加速動力。
此外,由於研究人員能夠以這種破解法取得該資訊娛樂系統的 root 權限,因此也能夠竊得車主的多種機敏個人資料,包括車主個人資訊、通訊錄內容、行事曆項目、電話通聯紀錄、Spotify 與 Gmail 連線階段的 cookie、Wi-Fi 密碼、曾造訪過的地點等多項資訊。
研究人員也說,這個破解方式也能夠讓車輛在尚未支援的地區行駛,並且讓車主可以自行進行車輛維修、系統修改等。
研究團隊在找到破解的概念驗證方法後,隨即通報 Tesla 原廠;Tesla 原廠在稍後發表聲明,指出該團隊用以破解以啟動電熱椅的方法,僅適用於舊版 Tesla 韌體,新版韌體已加強安全簽署流程;然而研究團隊指出該攻擊方法照樣可適用於目前推出的最新版韌體。
此外,有部分媒體在相關報導中指出,可利用該破解法啟用「完全自動駕駛」(Full Self-Driving, FSD)功能,但該團隊指出報導是錯誤的,並無法使用該破解方式啟用 FSD。
建議智慧車輛車主對此類破解消息應謹慎處理,避免自行套用,以免影響行車安全。
