netfilter is a set of hooks inside the Linux kernel that allows kernel modules to register callback functions with the network stack. A registered callback function is then called back for every packet that traverses the respective hook within the network stack.

It detects hidden processes using three techniques:

1. The proc technique consists of comparing /proc with the output of /bin/ps.
2. The sys technique consists of comparing information gathered from /bin/ps with information gathered from system calls.
3. The brute technique consists of bruteforcing the all process IDs. This technique is only available on Linux 2.6 kernels.
