摘要

起初,取证仅限于研究存储在系统硬盘上的数据。然而,随着存储容量和数据加密的增加,应用传统的数字取证程序变得更具挑战性。因此,内存取证技术被开发出来,或者经常被称为实时取证,因为这个过程更快、更复杂。易失性内存取证(通常称为实时取证)对于这种情况是必要的。实时取证存在缺陷,特别是当计算机处于活动VSM(虚拟安全模式)时,某些程序可能会失败。这导致可收回的证据丢失。因此,确定原因是必要的。基于软件的内存采集工具Autopsy、Isobuster、DumpIt和Magnet RAM capture就是其中的几个例子。根据实验结果,已经崩溃的工具包括DumpIt v1.3.2.20110401。以WindBg为工具进行动态代码分析,研究VSM对内存获取工具的影响。本研究的目的是在各种法医仪器中识别坠机实例,这将对法医专家进行调查非常有用。

ANALYSIS OF THE EFFECT OF VSM ON THE MEMORY ACQUISITION PROCESS USING THE DYNAMIC ANALYSIS METHOD
At first, forensics was restricted to studying data that was stored on a system's hard disk. However, as storage capacity and data encryption increased, applying conventional digital forensic procedures became more challenging. As a result, memory forensics techniques are developed, or are frequently referred to as live forensics, because the process is quicker and more sophisticated. Volatile memory forensics, often known as live forensics, are necessary for this condition. Live forensics has flaws, specifically that some programs can fail when the computer is in active VSM (virtual secure mode). This results in the retrievable evidence being lost. Therefore, determining the cause is essential. The software-based memory acquisition tools Autopsy, Isobuster, DumpIt, and Magnet RAM Capturer are just a few examples. According to the findings of the experiments, the tools that have crashed include DumpIt v1.3.2.20110401. A dynamic code analysis using WindBg as a tool was utilized to study the impact of VSM on the memory acquisition tool. This study's goal is to identify the instances of crashes in various forensic instruments, which will be highly useful for forensic experts performing investigations.
