There are so many tools that able to check the hidden process and port, the tools are rootkits/lkms/unhide etc.
In this tutorial i will discuss something more simple to use and the tools is UNHIDE.

Unhide is a tool to find hidden processes and TCP/UDP ports by rootkits / LKMs or by another hidden technique. This tools works under both Linux / Unix, and MS-Windows operating systems.

It detects hidden processes using three techniques:

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

WebDAV (Web-based Distributed Authoring and Versioning) is a way to share files over HTTP, much like you would use Samba or NFS.

It has more limitations, and less speed, than file systems like Samba or NFS, but with the proliferation of Web servers and the ability to reach Web sites from multiple clients in various locations, WebDAV certainly has its appeal. Unlike Samba or NFS, which are best suited for local area networks, you can use an HTTP server anywhere in the world and likewise access it from anywhere.

WebDAV support is also baked right into most modern operating systems (OS), making it extremely easy to access as a client. Setting it up on the server, however, may be more of a challenge. Certainly setting it up correctly can be.

What is DD ?

dd is a common Unix program whose primary purpose is the low-level copying and conversion of raw data. dd is an application that will "convert and copy a file" [1] according to the referenced manual page for Version 7 Unix and is most likely inspired from DD found in IBM JCL, and the command's syntax is meant to be reminiscent of this;[2] in JCL, "DD" stands for Data Description. dd is used to copy a specified number of bytes or blocks, performing on-the-fly byte order conversions, as well as more esoteric EBCDIC to ASCII conversions.[3] dd can also be used to copy regions of raw device files, e.g. backing up the boot sector of a hard disk, or to read fixed amounts of data from special files like /dev/zero or /dev/random.
