HiddenWall - Tool to generate a Linux kernel module for custom rules with Netfilter hooking. (block ports, Hidden mode, rootkit functions etc)

HiddenWall is a Linux kernel module generator for custom rules with netfilter. (block ports, Hidden mode, rootkit functions etc). The motivation: on bad situation, attacker can put your iptables/ufw to fall... but if you have HiddenWall, the attacker will not find the hidden kernel module that block external access, because have a hook to netfilter on kernel land(think like a second layer for firewall).
