Parameters
----------
jail : Jail
The jail which the action belongs to.
name : str
Name assigned to the action.
category : str
Valid badips.com category for reporting failures.

Minimum score for bad IPs. Default 3.
age : str, optional
Age of last report for bad IPs, per badips.com syntax.
Default "24h" (24 hours)
banaction : str, optional
Name of banaction to use for blacklisting bad IPs. If `None`,

of blacklist IPs.
updateperiod : int, optional
Time in seconds between updating bad IPs blacklist.
Default 900 (15 minutes)

# IPThreat configuration file
#
# Added to fail2ban by Jeff Johnson (jjxtra)
#
# Action to report IP address to ipthreat.net
#
# You must sign up to obtain an API key from ipthreat.net and request bulk report permissions
# https://ipthreat.net/integrations
#
# IPThreat is a 100% free site and service, all data is licensed under a creative commons by attribution license
# Please do not integrate if you do not agree to the license
#
# IMPORTANT:
#
# Reporting an IP is a serious action. Make sure that it is legit.
# Consider using this action only for:
# * IP that has been banned more than once
# * High max retry to avoid user mis-typing password
# * Filters that are unlikely to be human error
#
# Example:
# ```
# action = %(known/action)s
# ipthreat[]
# ```
#
# The action accepts the following arguments: ipthreat[ipthreat_flags="8",ipthreat_system="SSH", ipthreat_apikey=...]
# In most cases your action could be as simple as: ipthreat[], since the default flags and system are set to the most correct default values.
# You can optionally override ipthreat_system and ipthreat_flags if desired.
# The ipthreat_apikey must be set at the bottom of this configuration file.
#
# `ipthreat_system` is a short name of the system attacked, i.e. SSH, SMTP, MYSQL, PHP, etc.
#
# For `ipthreat_flags`, most cases will use 8 (BruteForce) which is the default, but you could use others.
# You can use the name or the ordinal.
# Multiple values are comma separated.
# ```
# Name Ordinal Description
# Dns 1 Abuse/attack of dns (domain name server)
# Fraud 2 General fraud, whether orders, misuse of payment info, etc
# DDos 4 Distributed denial of service attack, whether through http requests, large ping attack, etc
# BruteForce 8 Brute force login attack
# Proxy 16 IP is a proxy like TOR or other proxy server
# Spam 32 Email, comment or other type of spam
# Vpn 64 IP is part of a VPN
# Hacking 128 General hacking outside of brute force attack (includes vulnerability scans, sql injection, etc.). Use port scan flag instead if it's just probe on ports.
# BadBot 256 Bad bot that is not honoring robots.txt or just flooding with too many requests, etc
# Compromised 512 The ip has been taken over by malware or botnet
# Phishing 1024 The ip is involved in phishing or spoofing
# Iot 2048 The ip has targetted an iot (Internet of Things) device
# PortScan 4096 Port scan
# See https://ipthreat.net/bulkreportformat for more information
