## Mimikatz commands
|
||
|
||
| Command |Definition|
|
||
|:----------------:|:---------------|
|
||
| CRYPTO::Certificates|list/export certificates|
|
||
|CRYPTO::Certificates | list/export certificates|
|
||
|KERBEROS::Golden | create golden/silver/trust tickets|
|
||
|KERBEROS::List | list all user tickets (TGT and TGS) in user memory. No special privileges required since it only displays the current user’s tickets.Similar to functionality of “klist”.|
|
||
|KERBEROS::PTT | pass the ticket. Typically used to inject a stolen or forged Kerberos ticket (golden/silver/trust).|
|
||
|LSADUMP::DCSync | ask a DC to synchronize an object (get password data for account). No need to run code on DC.|
|
||
|LSADUMP::LSA | Ask LSA Server to retrieve SAM/AD enterprise (normal, patch on the fly or inject). Use to dump all Active Directory domain credentials from a Domain Controller or lsass.dmp dump file. Also used to get specific account credential such as krbtgt with the parameter /name: “/name:krbtgt”|
|
||
|LSADUMP::SAM | get the SysKey to decrypt SAM entries (from registry or hive). The SAM option connects to the local Security Account Manager (SAM) database and dumps credentials for local accounts. This is used to dump all local credentials on a Windows computer.|
|
||
|LSADUMP::Trust | Ask LSA Server to retrieve Trust Auth Information (normal or patch on the fly). Dumps trust keys (passwords) for all associated trusts (domain/forest).|
|
||
|MISC::AddSid | Add to SIDHistory to user account. The first value is the target account and the second value is the account/group name(s) (or SID). Moved to SID:modify as of May 6th, 2016.|
|
||
|MISC::MemSSP | Inject a malicious Windows SSP to log locally authenticated credentials.|
|
||
|MISC::Skeleton | Inject Skeleton Key into LSASS process on Domain Controller. This enables all user authentication to the Skeleton Key patched DC to use a “master password” (aka Skeleton Keys) as well as their usual password.|
