How to Delete OR Format files unrecoverable way

Today probably every computer user know and used to get use of a recovery software to recover deleted files and folders. Those softwares are very useful when we delete some important files let's say you have a photograph that only in your PC and you've mistakenly deleted it. So then recovery software is like came from heaven. But on the other hand think you formatted your hard disk and you sold it out. And the photograph that you're bothered should be a very private one. And the guy who got your PC recover your hard disk from the same manner that you recovered your photograph. So he got your photographs and what do you think he will gonna do with it.

The most important thing with data is private and confidential which are deserved. So when we come to the point of data confidential, data recovery becomes very critical. So let's look how to remove a file forever and ever.

First we will look how files can be recovered. Actually any data on a disk / flash drive cannot be erase like you erase pencil marks on a book. When the data have written on the disk they last forever. Then you may ask "If files cannot be deleted what are we do by deleting files?". You may know File Allocation Table (FAT). (If you want to get some idea of file allocation table and what is file system means look What are File Systems). File Allocation Table has links to data on the disk with files names , attribs ,... So when we have deleted a file , actually its deleted from this FAT table. It's remove the link to the data on the disk from the label of the file. But on the disk the real data (ones and zeros) are exist and they will remain until we over write some data on top of it. The data recovery software is doing , scan for those data on the hard disk. Some times you may have seen when we scan hard / flash drive from a recovery software some file indicate as unrecoverable. Those are files which are over written by other data. When data is over written they cannot be recoverable. There is a phrase "Data cannot be deleted but can be over written".

Windows Hacking Tool INTERCEPTER

There are several windows based hacking tools very useful for day to day hackings. Intercepter is also one of that. There is a linux version also. Any way let's take look at this handy tool.

What are File Systems and How to Open Linux Partitions in Windows

What are file systems?

As simply it is the system of Writing or Retrieving our data on/from a disk or flash drive or any other storage media in systematic way. If there is no file system, a hard drive will be only a disk with ones and zeros that can not be read by a computer because there is no way to find the data position.

Let's assume a Library with thousands of books. Normally in a library it has sections. like Science, History, Fictions, Novels etc. And in a particular section also there may be categorized sub section like Bio science, Electronic Science, Computer Science in Science section. In a particular sub section there may have a Rack or Racks with Rows and columns numbered which a particular cell get a unique combination. In a particular cell there may have 5 books. The librarian has a table of every book of the library describes in which section's in which sub section's in which rack's and in which cell is the book placed.

So if we go to this library and ask from the librarian about a book of "Beginning for Electronic circuits" she/he may look at the table and go through Science section and in Electronic sub section and find the book and locating where is the cell. So librarian will say to you "son, go to science section and then in electronic sub section.Then go to 3rd rack's AZ cell. The book you are finding is there.". So you can find the cell and get the book easily.

How to make a remote desktop connection on Linux and Windows

Here we are going to talk about how to make remote desktop connections in Linux and Windows OSs. I think you know how to establish a RDP connection to windows machine from another windows machine. So firstly i will talk about how to establish a RDP connection to a Windows machine from Linux machine.

Note : This demonstration is for Ubuntu and Kali like linux machines

RDP from Windows to Linux
  
Get the terminal. And type apt-get install xrdp

It will install the XRDP on your linux system. Then type service start xrdp
This will start the XRDP service on your linux machine.

Now in the terminal type whoami. This will show you the host name of your linux. Remember it. And type ifconfig find your ip address and keep in mind.
Go to your Windows machine and get run and type mstsc. Type your linux machine's IP and click on connect. Then a windows will come with black background popup for input username and password. Make sure in front of the Module has selected the Sesman-Xvnc. On the Username field type the Hostname of your linux. On the password type it's password (login password for your linux). Click on OK. Then RDP connection to the linux machine will come.

RDP from Linux to Windows


Install XRDP in Linux machine as above. Get the terminal and type rdesktop and enter. If it say rdesktop has to be install type apt-get intall rdesktop. Then type rdesktop [IP address] . In the [IP address] type your windows machine's IP addres and enter. Then in a new windows it will open up the remote desktop connection to the windows machine. Some times you may get an error of "Failed to connect , CredSSP required by server". For this go to your windows machine and got remote connection properties (Right click Comuter > Properties > Remote Settings >)  Under the Allow Remote connection to this computer remove the tick for Allow connections only from computers running Remote Desktop with Network Level Authentication(recomended). Its for Windows 8. In Windows 7 go to Remote connection settings and select the middle one which is Allow connections from computers running any version of Remote Desktop (less secure). Then connect again from your linux machine.

You can give any resolution for the RDP windows like this. Lets say you want 1320x1020 resolution for the RDP connection... type

rdesktop [IP Address] -g 1320x120

RDP with linux two linux machine also can be done in same manner. Type rdesktop [IP Address] in the other linux machine. You can get the Remote desktop connection.
