CREATE A BOOTABLE USB

Creating a bootale usb in Linux is much easier than that in Windows.

First what you need to have is the iso image of the OS which you wish to install, which can be either downloaded from the internet. In case you do not have an iso but you have the setup files, in the sense all the files that are to be included in the iso, then you should create an iso with those files.

In ubuntu or anyother Linux distros, it can be done the following way:Select all the files to be included in the iso image and right click and then select CompressA window apppers asing for the location and the type of the compressed file. There you select .iso and click 'Create'.It is done

Now, after you have the iso image ready, place it in an accessable directory. To simplify the case, lets put it in the Desktop. Then folow the steps,

Open the terminal (Ctrl+Alt+T).Type in

sudo fdisk -l.

This command will give you the list of all the harddrives connected to you PC and there you can can find out the name of your flash drive. It will be in the form /dev/sdb<?>

Then change the working directory to the location where you have placed the iso. Here we are in the Desktop. So, type in cd Desktop/. (In general, cd /home/userName/path)sudo dd if=iso_name.iso of=/dev/sdb/<?>

Here, iso_name refers to the name of the iso which you want to write to the flash drive and /dev/sdb<?> is the name of your USB/flash drive.

Wait for a few minutes till the process is completed. When completed successfully, few messages will be displayed. Later you can reboot your PC to install the OS.

In windows, there are applications like rufus which is a very small and effecient portable application which allows you to boot a USB Drive.

MORE ABOUT RANSOMWARES. PART 1

Not long ago, a man committed suicide after an automatically generated notice from a computer virus threatened him with jail unless he paid a ransom thousands of dollars. The year was 2014. As incredible as the story seems, it marked the first known time a computer virus actually killed somebody. The next generations stole cash from users around the globe, and Cryptolocker raised the stakes – holding data of hundreds of thousands of users hostage. Despite successive short-lived take downs, the malware has made a comeback as CTB (Curve-Tor-Bitcoin) Locker. This challenging breed of malware is continuously improving, reaching new levels of complexity as smartphones and tablets are increasingly used to store crucial personal and enterprise-level documents. Bitdefender, the anti-malware solutions provider, zooms in on the subject to show how this type of virus works and to tell users how to prevent being locked out and extorted. What is ransomware? Ransomware is a type of malware th...

SQL INJECTION

SQL in Web Pages In the previous chapters, you have learned to retrieve (and update) database data, using SQL. When SQL is used to display data on a web page, it is common to let web users input their own search values. Since SQL statements are text only, it is easy, with a little piece of computer code, to dynamically change SQL statements to provide the user with selected data: Server Code txtUserId = getRequestString (" UserId "); txtSQL = "SELECT * FROM Users WHERE UserId = " + txtUserId ; The example above, creates a select statement by adding a variable (txtUserId) to a select string. The variable is fetched from the user input (Request) to the page. The rest of this chapter describes the potential dangers of using user input in SQL statements. SQL Injection SQL injection is a technique where malicious users can inject SQL commands into an SQL statement, via web page input. Injected SQL commands can alter SQL statement and com...
