SQL injection

SQL Injection merupakan cara hack website yang paling banyak digunakan oleh para hacker. Kenapa? Karena dengan melakukan SQL injection, kita dapat langsung mengetahui username dan password dari website yang akan kita bajak. Kok bisa gitu? Kasih tau gak yah? hehe, ya udah siapin kopi dulu sana terus lanjut bacanya karena untuk melakukan teknik ini dibutuhkan kesabaran ekstra,hehe..

Upload Vulnerability

Upload is process of transmitting a file from a computer system to other computer systems. Attacker to upload files to insert in accordance with the desired command so that it can remotely victim. This attack is passive as it waits for the victim to take action on a file that is uploaded.

XSS

XSS is a hacking technique that uses a script-injection method with a certain gap in a web page. The gap can sometimes be through the input form, or by modifying the URL parameter. The script that is injected, there are several kinds, can HTML tags, JavaScript, PHP, ASP (as web server), etc.

There are two methods used in using the XSS :

Magic Number

       A magic number or sometimes referred to as a file signature is a number embedded at or near the beginning of a file that indicates its file format (i.e., the type of file it is). magic number can be viewed using a hex editor.
       for example, the magic number for JPEG (Joint Photographic Experts Group) image files is 0x4A464946, which is the ASCII equivalent of JFIF (JPEG File Interchange Format). However, JPEG magic numbers are not the first bytes in the file; rather, they begin with the seventh byte.
       Similarly, the magic number for image files having the subsequently introduced GIF89a format is 0x474946383961. For both types of GIF (Graphic Interchange Format) files, the magic number occupies the first six bytes of the file. They are then followed by additional general information (i.e., metadata) about the file.

Slack Space

Slack space is the area between the end of a file and end of the last cluster or sector used by the file in question. Area is an area that will not be used again to store the information there, so the area is "wasted" useless. Slackspace is common in file systems that use a large cluster size, while the file system that uses a small cluster size can organize the storage media more effectively and efficiently.Amount of wasted disk space can be thought is estimated by multiplying the number offiles (including the number of directories) with half the size of a cluster.

Unallocated Space

Unallocated Space is available disk space that is not allocated to any volume. The type of volume that you can create on unallocated space depends on the disk type. On basic disks, you can use unallocated space to create primary or extended partitions. On dynamic disks, you can use unallocated space to create dynamic volumes
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 drive is no longer required to be “allocated” it becomes unallocated. This means that  new files can now be re-written to that location.
On a standard, working computer, files can only be written to the unallocated space.
If a newly formatted  drive is connected to a computer, virtually all of the drive space is unallocated space (a small amount of space will be taken up by files within the file system, e.g $MFT, etc). On a new drive the unallocated space is normally zeros, as files are written to the hard drive the zeros are over written with the file data
