Volatility Analysis
Volatilityによるメモリフォレンジック
セキュリティコンテストで
初メモリフォレンジックの問題に挑戦したが
惨敗です。。。
メモリフォレンジックといえば
Volatility Framework を使うらしいので
調べた使い方をまとめとく
- インストール方法（mac）
$ brew install volatility
- とりあえずヘルプを見てみる
$ vol.py -h Volatility Foundation Volatility Framework 2.5 Usage: Volatility - A memory forensics analysis platform. Options: -h, --help list all available options and their default values.

plugin directories to use (colon separated) --info Print information about all registered objects --cache-directory=/Users/Tk/.cache/volatility Directory where cache files are stored --cache Use caching --tz=TZ Sets the (Olson) timezone for displaying timestamps using pytz (if installed) or tzset -f FILENAME, --filename=FILENAME Filename to use when opening an image --profile=WinXPSP2x86 Name of the profile to load (use --info to see a list of supported profiles) -l LOCATION, --location=LOCATION A URN location from which to load an address space -w, --write Enable write support --dtb=DTB DTB Address --shift=SHIFT Mac KASLR shift address --output=text Output in this format (support is module specific, see the Module Output Options below) --output-file=OUTPUT_FILE Write output in this file -v, --verbose Verbose information -g KDBG, --kdbg=KDBG Specify a KDBG virtual address (Note: for 64-bit Windows 8 and above this is the address of KdCopyDataBlock) --force Force utilization of suspect profile --cookie=COOKIE Specify the address of nt!ObHeaderCookie (valid for Windows 10 only) -k KPCR, --kpcr=KPCR Specify a specific KPCR address Supported Plugin Commands: amcache Print
