Techniques Used

Domain ID Name Use
Enterprise T1134 .005 Access Token Manipulation: SID-History Injection

Mimikatz's MISC::AddSid module can append any SID or user/group account to a user's SID-History. Mimikatz also utilizes SID-History Injection to expand the scope of other components such as generated Kerberos Golden Tickets and DCSync beyond a single domain.[2][3]

Enterprise T1098 Account Manipulation

The Mimikatz credential dumper has been extended to include Skeleton Key domain controller authentication bypass functionality. The LSADUMP::ChangeNTLM and LSADUMP::SetNTLM modules can also manipulate the password hash of an account without knowing the clear text value.[2][4]

Enterprise T1547 .005 Boot or Logon Autostart Execution: Security Support Provider

The Mimikatz credential dumper contains an implementation of an SSP.[1]

Enterprise T1555 Credentials from Password Stores

Mimikatz performs credential dumping to obtain account and password information useful in gaining access to additional systems and enterprise network resources. It contains functionality to acquire information about credentials in many ways, including from the credential vault and DPAPI.[1][5][6][7][8]

.003 Credentials from Web Browsers

Mimikatz performs credential dumping to obtain account and password information useful in gaining access to additional systems and enterprise network resources. It contains functionality to acquire information about credentials in many ways, including from DPAPI.[1][5][6][7]

.004 Windows Credential Manager

Mimikatz contains functionality to acquire credentials from the Windows Credential Manager.[9]

Enterprise T1003 .001 OS Credential Dumping: LSASS Memory

Mimikatz performs credential dumping to obtain account and password information useful in gaining access to additional systems and enterprise network resources. It contains functionality to acquire information about credentials in many ways, including from the LSASS Memory.[1][5][6][7]

.002 OS Credential Dumping: Security Account Manager

Mimikatz performs credential dumping to obtain account and password information useful in gaining access to additional systems and enterprise network resources. It contains functionality to acquire information about credentials in many ways, including from the SAM table.[1][5][6][7]

.004 OS Credential Dumping: LSA Secrets

Mimikatz performs credential dumping to obtain account and password information useful in gaining access to additional systems and enterprise network resources. It contains functionality to acquire information about credentials in many ways, including from the LSA.[1][5][6][7]

.006 OS Credential Dumping: DCSync

Mimikatz performs credential dumping to obtain account and password information useful in gaining access to additional systems and enterprise network resources. It contains functionality to acquire information about credentials in many ways, including from DCSync/NetSync.[1][5][6][7][8]

Enterprise T1207 Rogue Domain Controller

Mimikatz’s LSADUMP::DCShadow module can be used to make AD updates by temporarily setting a computer to be a DC.[1][2]

Enterprise T1649 Steal or Forge Authentication Certificates

Mimikatz's CRYPTO module can create and export various types of authentication certificates.[2]

Enterprise T1558 .001 Steal or Forge Kerberos Tickets: Golden Ticket

Mimikatz's kerberos module can create golden tickets.[10][8]

.002 Steal or Forge Kerberos Tickets: Silver Ticket

Mimikatz's kerberos module can create silver tickets.[10]

Enterprise T1552 .004 Unsecured Credentials: Private Keys

Mimikatz's CRYPTO::Extract module can extract keys by interacting with Windows cryptographic application programming interface (API) functions.[2]

Enterprise T1550 .002 Use Alternate Authentication Material: Pass the Hash

Mimikatz's SEKURLSA::Pth module can impersonate a user, with only a password hash, to execute arbitrary commands.[2][7][8]

.003 Use Alternate Authentication Material: Pass the Ticket

Mimikatz’s LSADUMP::DCSync and KERBEROS::PTT modules implement the three steps required to extract the krbtgt account hash and create/use Kerberos tickets.[2][3][11][7]

Groups That Use This Software
