WHAT IS RASPBERRY PI ? EVERYTHING YOU SHOULD KNOW ABOUT PI..

TECHBYTE: Ever wondered that you have a small credit card-sized computer that you can keep that in your pocket and do mostly all the thing that you do with a desktop or with your laptop. Then yes it is possible, in this post you will know all about RASPBERRY PI.

                               The Raspberry Pi is a credit card-sized computer that plugs into your TV and a keyboard. It is a capable little computer which can be used in electronics projects, and for many of the things that your desktop PC does, like spreadsheets, word processing, browsing the internet, and playing games.

     The Pi is developed by the Raspberry Pi Foundation, which is a registered charity in the UK and aims to promote the study of science and other topics.

               

                  This small sized Raspberry Pi  computer comes with the board features a processor, RAM and typical hardware ports you find with most computers like HDMI port , USB , Ethernet  ports , Card reader and many more things that you use in your desktop.

     This means you’re able to do most things a desktop computer can do such as document editing, playing HD video, playing games, coding and much more.

The main operating system for the Pi is Raspbian and is based of Debian. It is a distribution of Linux so you will probably find it a little different if you’re use to a Windows computer. Besides Raspbian you can install other operating systems such as Ubuntu mare, Ubuntu Core, OSMC, RIS OS, Windows 10 IoT and much more. Recently Linux Based SUSE has released the first official 64-bit Linux-based operating system for Raspberry Pi 3.

   There are 3 different models of the Pi that you will currently find . 

•  The original Raspberry Pi 1 Model A was released on February 2012.
•  Raspberry Pi 1 Model A+ was released in November 2014.
•  Raspberry Pi 1 Model B and Pi 1 Model B+.

       The original and first Raspberry Pi included a 700 MHz processor and came with 256MB RAM.The  Raspberry Pi 2 chip came with a quad-core Cortex-A7 900 MHz CPU and 1GB RAM and a Gpu equal to that of 2001 Xbox.
The Raspberry Pi 3 is the latest version of the Pi and beats version 2 in performance and features.
 that are- 

• Broadcom BCM2387 chipset
• The 1.2GHz 64-bit quad-core ARM Cortex-A53 CPU
• Integrated 802.11n wireless LAN and Bluetooth 4.1
• 40 pin extended GPI
• 4x USB 2.0 ports
• Stereo out and composite video port
• HDMI Port
• CSI (Camera Interface Interface) and DSI (Display Serial Interface) ports
• Micro SD card slot
• Micro USB power source

Recently, the Pi Foundation released an official touch display for Raspberry Pi. If you want to get started  with Raspberry Pi, you need to buy the appropriate parts like Raspberry P board, SD cards, USB power supply cable and other little things.

WHAT IS "MIRAI BOTNET" ? WHY SOMEONE IS TRYING TO SHUT DOWN THE INTERNET OF AN ENTIRE COUNTRY USING IT

TECHBYTE: Over the week , someone just used Mirai Botnet to knock the entire country offline. The attack was done on a small African country Liberia  sending it almost entirely offline each time.Botnet 14 also known as Mirai Botnet was responsible for this attack.

          Mirai is a piece of malware designed to hijack busybox systems (commonly used on IoT devices) in order to perform DDoS attacks. It  turns computer systems running Linux into remotely controlled "bots", that can be used as part of a botnet in large-scale network attacks.

       It uses the insecure Internet of Things devices and directs a massive amount of traffic to an online service or website. Some days ago  the cyber attack on Dyn DNS that resulted in shutting down of many popular websites like Reddit, GitHub, and Netflix.

     

              Now someone is trying to take down the whole Internet of a country by launching massive distributed denial-of-service (DDoS) attacks using a botnet of insecure IoT devices infected by the Mirai malware. Now it appears that Mirai knocked an entire country offline using another Mirai IoT botnet known as Botnet 14.

        Why someone tried this attack on a little-known country Liberia whose population is  around 4.5 million and where fewer than 10 per cent of its citizens have Internet access and the entire country is served by just two companies that share a single fiber optic cable. There is a possibility that someone is just testing the Mirai botnet’s capabilities.

      Security researcher Kevin Beaumont was one of the first peoples to notice this attack and wrote about this attack-

    “Shadows Kill” — Mirai DDoS botnet testing large scale attacks, sending threatening messages about UK and attacking researchers.

    Kevin names it as " Shadows Kill". Now  Mirau Botnet has been open source so anyone can use it . Liberia may be an example of knowing the capabilities of Mirai . The next step could be the entire continent or could have much bigger target.

CRITICAL VULNERABILITY IN WINDOWS DISCOVERED BY GOOGLE.

TECHBYTE: Google has disclosed a critical vulnerability in windows that affects Windows kernel. The windows bug has been reported to Tech giant about 10 days ago but it hasn't fix by Microsoft yet. After waiting the days after reporting Google has finally told people of that bug in windows .

         Search engine giant Google has posted critical vulnerability in the Windows kernel, an integral part of the operating system. The bug is Windows Kernel  can be used to escape security sandbox. Google warns Windows about that vulnerability on October 21, but Windows hasn't fix that issue yet.

In the technical term the bug vulnerability as fallows

"The Windows vulnerability is a local privilege escalation in the Windows kernel that can be used as a security sandbox escape. It can be triggered via the win32k.sys system call NtSetWindowLongPtr() for the index GWLP_ID on a window handle with GWL_STYLE set to WS_CHILD. Chrome's sandbox blocks win32k.sys system calls using the Win32k lockdown mitigation on Windows 10, which prevents exploitation of this sandbox escape vulnerability."

       

       Sandbox is a computer security term used to refer to the limits placed on users of applications and processes. Thus, a sandbox escape refers to breaking out of the virtual system and infiltrating others. Google's Chrome browser actively blocks the "escape" on Windows 10, but those using other browsers and other versions of Windows remain susceptible to an attack.

"This vulnerability is particularly serious because we know it is being actively exploited," Google said in a blog post on Monday. 

     This is not the first time Google has reported on bugs in Microsoft's operating system. Google has also reported  Adobe about the Flash vulnerability CVE-2016-7855 on October 21 and the same has been patched. To fix that users need to simply update the Adobe Flash on their  and it will also be available via Chrome auto-update.
