INTERTNET MALWARE

Hello everyone, today I want to say some words about digital basics, malware, types of malwares and maybe some words about social engineering. Nowadays computer network is so important part of everybody. Do you agree with me? I think you agree with me because it is absolutely clear.

The Internet provides a wide variety of opportunities for communication and development, but unfortunately it also has it dark side. Hackers are computer criminals who use technology to perform a variety of crimes: virus propagation, fraud, intellectual property theft, etc. Hackers differentiate themselves into three groups:

A white hat hacker, upon finding some flaw in a system, will report the flaw to the vendor of that system. For example, if a white hat hacker discovered some flaw in Red Hat Linux, he would then email the Red Hat company (probably anonymously) and explain exactly what the flaw is and how it was exploited. White hat hackers are often hired specifically by companies to do penetration tests.

A black hat hacker is the person normally depicted in the media. Once he/she gains access to a system, his/her goal is to cause some type of harm. He/she might steal data, erase files, or deface websites. Black hat hackers are sometimes referred to as crackers.

A gray hat hacker is normally a law-abiding citizen, but in some cases will venture into illegal activities.

Malware (malicious software) is software created to damage or alter the computer data or its operations. These are main types:

- Viruses are programs that spread by attaching themselves to executable files or documents.

- Worms are self-copying programs that have the capacity to move from one computer to another without human help, by exploiting security flaws in computer networks.

- Trojan horses are malicious programs disguised as innocent-looking files or embedded within legitimate software.

- Spyware, software designed to collect information from computers for commercial or criminal purposes, is another example of malicious software.

Digital technology has transformed the way we live and work, but it has also brought new dangers in the form of malware and social engineering. Malware, short for malicious software, is any program or code that is intended to cause harm to a computer system. There are many different types of malware, each with its own characteristics and methods of attack.

Some of the most common types of malwares include viruses, worms, trojans, and ransomware. A virus is a piece of code that can replicate itself and spread from one computer to another, while a worm is a self-replicating program

that can spread through a network. A trojan is a program that appears to be legitimate but actually contains malicious code, while ransomware is a type of malware that encrypts files on a victim’s computer and demands payment for their release.

While malware can be devastating, it is not the only threat to computer security. Social engineering is another tactic used by cybercriminals to gain access to sensitive information. This involves manipulating people into divulging confidential information or performing actions that could compromise security. For example, phishing emails may appear to be from a legitimate source but actually contain links to malicious websites or attachments that contain malware.

To protect yourself from these threats, it’s important to follow some basic digital security practices. This includes using strong passwords, keeping software and operating systems up to date, avoiding suspicious emails or links, and being cautious when downloading files from the internet. By staying informed and vigilant, we can continue to enjoy the benefits of digital technology without falling victim to its dangers.
