Hacking Cookies - Latest Hacking News

INTRODUCTION.
Most internet users are familiar with the term Cookie because we see it pop up in most websites but do we know the purpose it serves.

Let us start with what it is, a cookie ( also known as browser cookie, internet cookie, web cookie or HTTP cookie) is small piece of data that websites store on your disk in the form of a text file.Cookies allow websites to store specific information helpful to remember each visitor uniquely.

What do browser cookies do.
The purpose of the computer cookie is to help the website track of your visits and activity and is not a bad thing.A good example are the online retailers to keep track of the items in user's shopping cart as they explore the site, without the cookies the shopping cart would reset to zero with every click.

A website also uses the cookies to store information about you recent visits or record you login information which i do not really recommend from a security perspective

Types of browser cookies.

Session cookie
Session cookies comes in handy when one is navigating the web and does not have to be treated as a new visitor. The session cookie makes it possible  foe the website to keep track of the user information such as shopping cart account details and other preferences are not lost during navigation. A session cookie is stored temporary and is usually deleted on the closure of the browser.

Persistent Cookie
Also known as permanent cookie also facilitates websites to track user settings and information when they visit the same website in the future and it is not deleted upon closure of the browser. They are used to collect identifying information about the user and can be used to authenticate a user to the same websites upon revisits without having to log in again

Secure cookie
It is also known as HTTPOnly Cookie, is type of cookie that only works with HTTP/HTTPS and does not work with scripting languages like Javascript.Since it is only storing information and is used fro hypertext transfer protocols request and data over the internet , this now makes it hard for exploit's and hacks to be made through it , to add also cross-site scripting(XSS) can not happen because it prevents it from happening.


Third-party Cookie
Third -party Cookie are those cookies that originate from a website other than the one you are using which are used by advertisers or ad servers to track user behavior , and generate virtual user profiles.If you have ever seen an ad that is exactly matched to you recent web activity, fill the gaps, it is no coincidence.

TTY in linux and how to use it

Ok, how about we start with what is TTY.It stands for “teletypewriter.” What can tty tell us. In Linux, there is a pseudo-teletype multiplexor which handles the connections from all of the terminal window pseudo-teletypes (PTS). The multiplexor is the master, and the PTS are the "slaves". The multiplexor is addressed by the kernel through the device file located at /dev/ptmx. The tty command will print the name of the device file that your pseudo-teletype slave is using to interface to the master. And that, effectively, is the number of your terminal window. The output shows that we are connected to to the device file at /dev/pts/4. Our terminal window, which is a software emulation of a teletype (TTY), is interfaced to the pseudo-teletype multiplexor as a pseudo-teletype (PTS). And it happens to be number four.For the number at the end shows that. The Silent Option . The -s (silent) option causes tty to generate no output. This is how it will look on your terminal It do...

Virtualization Technology

    Virtualization is the process of running a virtual instance of a computer system in an abstract layer of the physical hardware.     It ensures efficient utilization of physical computer hardware and is the foundation of cloud computing.     Virtualization uses a software to create an abstraction layer over computer hardware that allows the hardware  elements of a single computer  such as processor, memory , storage and more to be divided into multiple virtual computers , commonly called virtual machines(VMs)     Each VM  runs its own operating system and behaves like an independent computer, even though it is running on just a portion of the actual underlying hardware.     This is the technology that drives the cloud computing economics. This enables cloud providers to serve users with their existing physical computer hardware; it enables cloud users to purchase only the computer in resources they need when ...
