| `SECONDARY_DIR` | `C:\` | This is the secondary target, it's less important but nice-to-have with the upload / backup / exfiltration once the primary copy is completed. The target can be a directory or a single file. |
|
||||
| `LOGFILE` | `C:\Windows\Temp\nc_pull.log` | This file is how the script has "persistence". In case the computer is shut down, rebooted, etc, when it comes back online and the script is re-ran against it, it reads this file to pick up where it last was, and attempts to resume from that point. If this transfer is meant to be hidden, put this file somewhere someone is not likely to find it easily. |
