90s, and has since reached a user-base that spans industries and continents. For those in the know, you understand that Linux is actually everywhere. It’s in your phones, in your cars, in your refrigerators, your Roku devices. It runs most of bitcoin linux tutorial pdf Internet, the supercomputers making scientific breakthroughs, and the world’s stock exchanges.

Just like Windows XP, Windows 7, Windows 8, and Mac OS X, Linux is an operating system. An operating system is software that manages all of the hardware resources associated with your desktop or laptop. The Bootloader: The software that manages the boot process of your computer. For most users, this will simply be a splash screen that pops up and eventually goes away to boot into the operating system. The kernel is the core of the system and manages the CPU, memory, and peripheral devices. The Shell: You’ve probably heard mention of the Linux command line.

This is no longer the case. With modern desktop Linux, there is no need to ever touch the command line. Desktop Environment: This is the piece of the puzzle that the users actually interact with. Applications: Desktop environments do not offer the full array of apps. Just like Windows and Mac, Linux offers thousands upon thousands of high-quality software titles that can be easily found and installed. App Store-like tools that centralize and simplify application installation. The Linux Foundation is a non-profit consortium enabling collaboration and innovation through an open source development model.

Kali Installation is not our speciality, read up multiple website and watch youtube videos for installation. The first category comprises the typical viruses that infect your computers, get inside your USB, copy themselves to every avenue they can. They slow down your computer, limit it’s functionality, and in general, make a lot of changes that make them easy to detect. These, in general, serve no particular useful purpose for the writer of the malicious code, other than perhaps giving them the lulz or maybe some sense of accomplishment. The second ones are the precisely crafted viruses called trojans. These hide behind legitimate files, spread only through very few avenues as seen fit by their programmer. Most viruses would copy themselves to all devices attached to the infected system, try to spread via the network, internet etc.

Trojans will not automatically copy themselves. They will stay hidden and inactive. As with everything else, the means of spread of trojan is also precise. The malicious code writer will hide them behind a legitimate file, and then spread this file using social networks, spam mails, etc.

This way, only those computers will get infected that the attacker wants to infect. These are trojans which, when installed on the system, silently position themselves in such a way that they allow the attacker to control the system remotely. Botnet – This is a special use of a freely spreading trojan whose purpose is to infect as many computers as possible with a RAT like functionality but less control on who gets infected. This reduced control and increase rate of spreading is important because of the purpose of a botnet. Botnet is basically a large network of infected computers which the attacker uses to do his bidding. They are often used to carry out DDOS attacks. That means he can easily say- “Give me money or I’ll delete all your files”.

Unfortunately for the attacker, once the victim sees this message, the trojan is no longer covert. So, the attacker needs to do something which is equivalent to deleting, but reversible. Also, the reverse procedure should require the consent of the attacker. There is one solution – Encryption. If you know what encryption is, then you should see by now what’s up. What the attacker can do is similar to what happens when you find a compressed archive with a password.
