Unallocated Space
Definition
Unallocated space is logical space on a operating system hard drive, e.g
Linux, can write to. To put it another way
it is the opposite of “allocated” space, which is where the operating system
has already written with files.
Examples.
If the operating system writes a file to a certain space
on the hard drive that part of the drive is now “allocated”, as the
file is using it the space, and no other files can be written to that section.
If that file is deleted then that part of the hard...
Slack Space
Slack space is harddisk portions not fully used by the current allocated file, and containing data from a previously deleted file.
The example save a 768 bytes file (User_File.txt) that requires only sector 1 and 1/2 sector 2. Depending on the operating system, the 256 bytes in sector 2 might be filled with 1′s or 0′s . Sectors 3 and 4 would not be overwritten and considered slack space. If the slack space contained...

Master Boot Record
A master boot record (MBR) is boot sector type from IBM Personal Computer consisting of a sequence of 512 bytes that is ocated at the first sector of a data storage device like hard disk. MBR is usually placed on storage devices.
The use of MBR are :
As a partition table holding, which describes the partitions of a storage device. In this context the boot sector may also be called a partition sector.
Operating system bootstraping. The BIOS built into a PC-compatible computer loads the MBR from the storage device and passes execution to machine...

Root Exploitation via Web Vulnerability (DVWA)
In this tutorial we will practice how to exploit via Web Vulnerability. We use DVWA as the web.
We will upload our payload via file upload facility in DVWA (high level), then execute nc command to open socket and listening (medium level), then execute our payload.
1. Information Gatherin using Zenmap
We know that the OS kernel is 2.6.3.9
2. Search exploit code in exploit db
/pentest/exploits/exploitdb# ./searchsploit 2.6.3.9
3. Because...

Combining Beef and Metasploit Framework
In last tutorial we practice using metasploit for exploiting the target and modify the webpage in target OS while inject it with beef code. Now, we will using web page injected with beef code. Then, we activate metasploit framework using meterpreter payload and keep it in listening process. So, when the target access our web page, we can exploit it using meterpreter.
Now, let's practice it.
First, try to make webpage included with beef code. To...
