Virtual machine introspection日期 2022 上傳時間 1-八月-2022 17:21:58 (UTC+8) 摘要 ARM硬體架構於行動裝置、個人電腦和雲端伺服器上面的市場份額占比越來越高，進而使針對ARM裝置的網路攻擊也隨之增加。因此，協助分析ARM裝置上的惡意攻擊行為的工具的需求也日益浮現。virtual machine introspection (VMI) 是一個利用virtual machine (VM) 來進行惡意軟體側錄跟惡意行為分析的技術，其先前在x86硬體架構上面已經有廣泛並且成熟的應用，然而此類工具在ARM裝置的支援仍然處遇前期的階段。本研究試圖利用QEMU，開發出一個能夠應用於ARM裝置上面的VMI系統。這個系統會專注於攔截並且側錄虛擬機器上面特定行程的函式呼叫。為了能夠開發出這樣的系統，我們在過程中面臨了兩個主要的問題：判斷需要監控的行程是否正在執行和如何在執行過程中攔截行程特定的函式呼叫。第一個問題我們主要利用行程的page table address跟ARM CPU上面的translation table base pointer比對，來解決判斷行程的問題。第二個問題我們利用了QEMU內部translation block的機制，進而找到適合的攔截函式呼叫的時機。在實作這個VMI系統時，我們修改了QEMU的tiny code generator，並且在每一次QEMU執行一個translation block之前，植入了我們部分的VMI的程式。這樣可以確保我們的VMI程式可以於惡意程式在被執行之前，獲得執行的控制權，讓惡意程式無法偵測到我們的執行，然後隱藏他的攻擊足跡。我們在QEMU monitor commands內加入了幾個方便使用者可以輸入的指令，讓使用者可以透過輸入指令的方式來進行程式側錄，並且將結果輸出成log檔案。最後我們針對這個VMI系統進行效能測量，平均的效能影響僅有4%。
Besides the mobile and IoT device market, ARM has gained more market share in the personal desktop and cloud server markets. Accordingly, the number of attacks against ARM devices has increased. Thus, the need for monitoring and analyzing the malware targeting ARM device has emerged. Virtual machine introspection (VMI) is a mature technology used for malware analysis and intrusion detection. Previous research mainly focuses on building VMI on x86, and there is little research on ARM. We chose QEMU as our hypervisor among all approaches because it can emulate a range of ARM processors and allow us to intercept function calls without context switching, which reduces code complexity.In this paper, we review QEMU`s tiny code generator and translation block and develop a naive approach to intercept function calls by inserting a small piece of code before each translation block is executed. We recognize the process by traversing the process list in the kernel using the QEMU built-in function. We identify the process by comparing the process`s page table pointer and ARM`s translation table pointer. To demonstrate the effectiveness and efficiency of our system, we first implement our VMI system as several QEMU monitor commands. The commands allow researchers to listen to a specific process`s execution and log its execution traces to log files. The benchmark results show an average performance degradation of 3.81 percent on single-threaded tasks and 4.88 percent on multi-threaded tasks.參考文獻 B. C.
