    Abstract: 隨著電信設備系統的成熟發展,簡訊系統所造成的系統安全問題逐漸增多,諸如透過簡訊散播惡意程式、進行詐騙、散佈廣告,或甚至藉此作為殭屍網路溝通的媒介等等。在卡巴斯基 2016 年第一季的報告,指出了新型手機惡意程式的散播中,簡訊型木馬占了 20.5 %,位居第二。有鑑於此,本篇論文提出了 SMS Helper 這個架構來解決這些簡訊系統相關的問題。本論文提供了兩個模式:雲端服務模式(cloud service mode)以及實機輔助模式(real device mode)。由於現今 Android 動態分析框架中,並無法真正地進行收發簡訊,而 SMS Helper 能夠幫助這些框架來達到這個功能。本系統確保簡訊紀錄的完整性,並增強了這些框架,使他們能夠更進一步檢測出惡意程式的簡訊行為,同時,虛擬環境下的運行能夠降低研究成本。除此之外,本篇論文指出了一個透過簡訊的方式,來指出 Android 應用程式所運行的環境是否為虛擬環境,並又藉由 SMS Helper 來規避這樣的檢測方式。接著,個人資料的洩漏導致廣告與詐騙,不斷的騷擾使用者,將 SMS Helper 套用於實體設備上,可以用來保護用戶手機號碼的隱私性。;As the mature technology development in telecommunication systems, the security issues caused by SMS are growing including propagation of malware, fraud, adverting and even botnets. In Q1 2016 reports issued by Kaspersky, SMS Trojan is occupied by 20.5% as second place of the distribution of new mobile malware. Thus, this paper proposes an architecture called SMS Helper aiming to provide a solution to addresses SMS-related issues. This paper provides two modes: cloud service mode and real device mode. Since current Android dynamic analysis frameworks cannot send and receive SMS messages authentically, SMS Helper can help these frameworks to send and receive messages. This system keep the integrity of SMS logs and strengthen the frameworks to observe malware’s further behaviors. Meanwhile, the virtual environment can low the cost of researches. In addition, this paper finds a new way to figure out the operating environment through SMS and by means of SMS Helper to evade this kind of detecting method. Also, the information leaks result in advisements and frauds harassing users frequently. SMS Helper can be adopted in a real device as well to protect the privacy of users’ real numbers.
