iphone data protection

以下為IOS 取證筆記

1.產生專用RAMdisk 檔案

2.用JB code

3.與ios 硬體裝置通訊

4.

原code 參考
http://code.google.com/p/iphone-data...on/wiki/README

如果要用OS X VM 請在這下載
http://kuai.xunlei.com/d/WMSBPYFNTZVX
密碼 HELLOWORLD
user 跟root password 都為9個s

ios ipsw和另外一個opensources專案下載參考點
https://github.com/KatanaForensics/LanternLite

另外取證lantern 下載點
http://katanaforensics.com/lantern/lanternlite


此OS X 要先裝xcode 套件

此套件也要安裝 http://mercurial.berkwood.com/
10.7 載點  http://mercurial.berkwood.com/binari...macosx10.7.zip
10.6 載點 http://mercurial.berkwood.com/binari...macosx10.6.zip
 

以下藍色要注意檔案位置跟名稱 .

準備套件環境 
sudo -s
root密碼9個s
curl -O http://networkpx.googlecode.com/files/ldid
chmod +x ldid
sudo mv ldid /usr/bin/

#install OSXFuse for img3fs 安裝osxfuse 套件
curl -O -L https://github.com/downloads/osxfuse/osxfuse/OSXFUSE-2.3.4.dmg
hdiutil mount OSXFUSE-2.3.4.dmg
sudo installer -pkg /Volumes/FUSE\for\ OS\ X/Install\ OSXFUSE\2.3.pkg -target /
hdiutil eject /Volumes/FUSE\for\ OS\ X/

#you will need these python modules 
sudo ARCHFLAGS='-arch i386 -arch x86_64' easy_install pycrypto
sudo easy_install M2crypto construct progressbar

#準備RAM disk 製作

hg clone https://code.google.com/p/iphone-dataprotection/ 
cd iphone-dataprotection

make -C img3fs/

curl -O -L https://sites.google.com/a/iphone-dev.com/files/home/redsn0w_mac_0.9.9b8.zip
unzip redsn0w_mac_0.9.9b8.zip
cp redsn0w_mac_0.9.9b8/redsn0w.app/Contents/MacOS/Keys.plist .

python python_scripts/kernel_patcher.py IOS5_IPSW_FOR_YOUR_DEVICE


sh ./make_ramdisk_n88ap.sh (這邊要注意生成不同的規格 ram disk 的sh不同 請照上面結果換) 

./redsn0w_mac_0.9.9b8/redsn0w.app/Contents/MacOS/redsn0w -i IOS5_IPSW_FOR_YOUR_DEVICE -r myramdisk.dmg -k kernelcache.release.n88.patched

#將usb port iphone 轉為本地port 
python usbmuxd-python-client/tcprelay.py -t 22:22221999:1999
可新增終端視窗
#現在ios 裝置 SSH  為 localhost:2222. 測試ios裝置是否與有連通
ssh -p 2222 root@localhost
若需要密碼則為alpine
測試連線無誤請按ctrl-z 跳出 

#解密碼指令
python python_scripts/demo_bruteforce.py

#將keychain整合 可看到帳號密碼
python python_scripts/keychain_tool.py -d UDID/keychain-2.db UDID/DATAVOLUMEID.plist

#鏡像指令
