## F-Secure's C3 Client script
|
|
|
|
This is a simple [F-Secure's C3](https://github.com/FSecureLABS/C3) client Python script offering a few functions to interact with C3 framework in an automated manner.
|
|
|
|
It connects to the C3 WebController (typically the one that's listening on port _52935_) and allows to issue API requests automating few things for us.
|
|
|
|
### Usage:
|
|
|
|
The script offers subcommands-kind of CLI interface, so after every command one can issue `--help` to get subcommand's help message.
|
|
|
|
|
|
**General help**:
|
|
|
|
```
|
|
PS D:\> py c3-client.py --help

usage: Usage: ./c3-client.py [options] <host> <command> [...] alarm relay [-h] [-e EXECUTE] [-x WEBHOOK] [-g gateway_id]
|
|
|
|
optional arguments:
|
|
-h, --help show this help message and exit
|
|
-e EXECUTE, --execute EXECUTE
|
|
If new Relay checks in - execute this command. Use following placeholders in your command: <computerName>, <userName>,
|
|
<domain>, <isElevated>, <osVersion>, <processId>, <relayName>, <relayId>, <buildId>, <timestamp> to customize executed
|
|
command's parameters. Example: powershell -c "Add-Type -AssemblyName System.Speech; $synth = New-Object -TypeName
|
|
System.Speech.Synthesis.SpeechSynthesizer; $synth.Speak('New Relay just checked-in
|
|
<domain>/<userName>@<computerName>')"
|
|
-x WEBHOOK, --webhook WEBHOOK
|
|
Trigger a Webhook (HTTP POST request) to this URL whenever a new Relay checks-in. The request will contain JSON message
|
|
with all the fields available, mentioned in --execute option.
|
|
-g gateway_id, --gateway-id gateway_id
|
|
ID (or Name) of the Gateway which Relays should be returned. If not given, will result all relays from all gateways.
|
|
```
|
|

|
|
|
|
- `list`

|
- `gateways` - list gateways in either JSON or text format
|
|
- `relays` - list relays in either JSON or text format

### Example Usage
|
|
|
|
**Example 1**
|
|
This example shows how to keep all of your Relays pinged every 45 seconds:
|
|
|
|
```
|
|
PS D:\> py c3-client.py http://192.168.0.200:52935 ping -k 45
|

[.] Sending a ping every 45 seconds.
|
|
[.] Pinged relay: matter4 from gateway gate4
|
|
[.] Pinged relay: mssql1 from gateway gate4
|
|
[.] Pinged relay: ldap9 from gateway gate4
|
|
[.] Pinged relay: mssql1 from gateway gate4
|
|
[+] Pinged 4 active relays.
|
|
|
|
[.] Sending a ping every 45 seconds.
|
|
[.] Pinged relay: matter4 from gateway gate4
|
|
[.] Pinged relay: mssql1 from gateway gate4
|
|
[.] Pinged relay: ldap9 from gateway gate4
|
|
[.] Pinged relay: mssql1 from gateway gate4
|
|
[+] Pinged 4 active relays.
|
|
|
|
```
|
|
|
|
**Example 2**
|
|
|
|
In this example setup an alarm that triggers upon new Relay checking-in. Whenever that happens, a command is executed with placeholders that will be substituted with values extracted from Relay's metadata:
|
|
|
|
```
|
|
PS D:\> py c3-client.py http://192.168.0.200:52935 alarm relay -g gate4 --execute "powershell -file speak.ps1 -message \`"New C3 Relay Inbound: <domain>/<userName>, computer: <computerName>\`""
