module ~ sekurlsa
This module extracts passwords, keys, pin codes, tickets from the memory of lsass
(Local Security Authority Subsystem Service
)
the process by default, or a minidump of it! (see: howto ~ get passwords by memory dump for minidump or other dumps instructions)
When working with lsass
process, mimikatz
needs some rights, choice:
- Administrator, to get
debug
privilege viaprivilege::debug
-
SYSTEM
account, via post exploitation tools, scheduled tasks,psexec -s ...
- in this casedebug
privilege is not needed.
Without rights to access lsass
process, all commands will fail with an error like this: ERROR kuhl_m_sekurlsa_acquireLSA ; Handle on memory (0x00000005)
(except when working with a minidump).
So, do not hesitate to start with:
mimikatz # privilege::debug
Privilege '20' OK
mimikatz # log sekurlsa.log
Using 'sekurlsa.log' for logfile : OK
...before others commands 😉
The information that can be extracted depends on the version of Windows and authentication methods: [en] http://1drv.ms/1fCWkhu
Starting with Windows 8.x and 10, by default, there is no password in memory.
Exceptions:
- When DC is/are unreachable, the
kerberos
provider keeps passwords for future negocation ; - When
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\SecurityProviders\WDigest
,UseLogonCredential
(DWORD) is set to1
, thewdigest
provider keeps passwords ; - When values in
Allow*
inHKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa\Credssp\PolicyDefaults
orHKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\CredentialsDelegation
, thetspkgs
/ CredSSP provider keeps passwords.
Of course, not when using Credential Guard.

Pass-The-Hash
mimikatz
can perform the well-known operation 'Pass-The-Hash' to run a process under another credentials with NTLM
hash of the user's password, instead of its real password.
For this, it starts a process with a fake identity, then replaces fake information (NTLM
hash of the fake password) with real information (NTLM
hash of the real password).
Arguments:
-
/user
- the username you want to impersonate, keep in mind that Administrator is not the only name for this well-known account. -
/domain
- the fully qualified domain name - without domain or in case of local user/admin, use computer or server name,workgroup
or whatever. -
/rc4
or/ntlm
- optional - the RC4 key / NTLM hash of the user's password. -
/aes128
- optional - the AES128 key derived from the user's password and the realm of the domain. -
/aes256
- optional - the AES256 key derived from the user's password and the realm of the domain. -
/run
- optional - the command line to run - default is:cmd
to have a shell.

Remarks:
- this command does not work with minidumps (nonsense);
- it requires elevated privileges (
privilege::debug
orSYSTEM
account), unlike 'Pass-The-Ticket' which uses one official API ; - this new version of 'Pass-The-Hash' replaces
RC4 keys
of Kerberos by thentlm
hash (and/or replacesAES
keys) - it permits to the Kerberos provider to askTGT
tickets! ; -
ntlm
hash is mandatory on XP/2003/Vista/2008 and before 7/2008r2/8/2012kb2871997
(AES
not available or replaceable) ; -
AES
keys can be replaced only on 8.1/2012r2 or 7/2008r2/8/2012 withkb2871997
, in this case you can avoidntlm
hash.

List and export Kerberos tickets of all sessions.
Unlike kerberos::list, sekurlsa
uses memory reading and is not subject to key export restrictions. sekurlsa
can access tickets of others sessions (users).
Argument:
-
/export
- optional - tickets are exported in.kirbi
files. They start with user'sLUID
and group number (0
=TGS
,1
=client ticket
(?) and2
=TGT
)
