rctf-bloodwatch

rctf-bloodwatch from redpwn but in Python. The only additional feature is selecting specific divisions to count (to exclude admins, for example).

Usage

argument	environment	required	default	type	description
-u / --url	RCTF_URL	yes	(none)	string	rCTF URL to monitor
-t / --token	RCTF_TOKEN	yes	(none)	string	rCTF API token
-d / --division	RCTF_DIVISION	no	all divisions	string	rCTF division(s) to include
-w / --discord-webhook	DISCORD_WEBHOOK	yes	(none)	string	Discord webhook URL
-m / --message	BLOOD_MESSAGE	yes	(none)	string	Message to send to webhook
-i / --interval	BLOOD_INTERVAL	no	60	integer	Seconds between checks
-l / --log-level	LOG_LEVEL	no	INFO	NOTSET | DEBUG | INFO | WARNING | ERROR | CRITICAL	Log level

Divisions

--division can be specified multiple times to include multiple divisions. Alternatively, specify a space-separated list in RCTF_DIVISION.

Message

--message is a template string with these variables available:

• challenge (challenge object)
• blooder (solve object)

See rCTF for the shape of these objects. Here's an example message:

Congratulations to [`{{ blooder.userName | replace("`", "") }}`](<https://ctf.tjcsec.club/profile/{{ blooder.userId }}>) for first blood on `{{ challenge.name }}`!

This sends a message that looks like this:
