What is the difference between a virus and a worm in UK and Ireland?

Hacker attacks are not just entertainment for programmers, as they were many years ago. Cyber attacks today are a serious criminal business that brings in millions of dollars. Unfortunately, not a single PC or other gadget user is 100% protected from virtual threats. Such attacks can await you at the most inopportune time, so it is important that you are prepared and can make the right decisions. Experts have divided online threats into 2 types: passive and active.

If your home PC is “attacked” by a virus, the consequences can be very unpleasant, including the failure of the entire system and data theft. However, if we are talking about large organizations, then the consequences of a cyber attack can cause serious financial and reputational losses for them. Let's find out in more detail what can harm your device and how to distinguish Internet threats from each other. It will also be useful for you to know which modern cyber security solutions will provide a reliable shield for your gadgets.

What are cyber attacks in UK and Ireland?

In simple terms, global cyber attack is a specific set of actions by virtual criminals that are aimed at web resources, databases, systems, or confidential info with the goal of stealing or destroying.

Cyber fraudsters or thieves use various methods to achieve their goals. Nowadays, gadgets have become much smarter, and almost everyone has access to the Internet. Home and office PCs are stuffed with various software, e-wallets with electronic money, and banking applications that have appeared where there is all the detailed information about the individual.

Any type of cyber attack is a huge danger for ordinary users and office computers. And the consequences of such attacks can be critical. Virtual attackers can blackmail users using bots, infiltrate the network through QR codes, and look for errors in the system in order to attack it with “brute force”.

Types of cyber threats

Malware has also evolved significantly, and without reliable protection, it can penetrate almost any system. Most dangerous software is aimed specifically at stealing bank data, but there are some that infect PCs with viruses and worms. There are also many other virtual attacks, and you need to be aware of them.

• DDoS attacks. In 2023, research was conducted among large corporations and cyber threats. This type of attack came first. The cybercriminal's goal is to make the system inaccessible. First, the hacker uses data from several corporate PCs as sources. Then, the entire OS becomes flooded with a huge number of requests and overloaded. Its throughput decreases sharply and makes the system inaccessible.
• Phishing. The second place in the above-mentioned study won these types of computer threats. Here, the danger lies in emails that come to the user on behalf of a popular company or the organization where he or she works. The disguised letter contains a link or file with a text message where there is a request to transfer personal data - bank account (card) number, password, or login. An attacker infects a link or file, and the virus penetrates the system, stealing data.
• Bot. This cyber security attack is one of the most effective because it is a robot that imitates human behavior. Its purpose is to perform tasks to increase user activity. There are harmless bots that maintain conversations with people and help them. But there are also dangerous bots. Their goal is to scan web portals and search for the slightest “holes”; after discovering them, the bot launches a cyber attack on the site. More often than not, this is a simple cyberattack that can be detected and quarantined in time by an experienced programmer.
• Brute-force. This method involves simply guessing the victim's password. The attacker uses scripts or an application that tries different password combinations to enter the user's profile. If your password is weak, it will most likely be determined. For this reason, many companies insist on strict password policies. Don't know how to set a strong password? Try the password manager integrated in some antivirus products or download the program separately.
• Worms. It is difficult to count how many computers were attacked by this target cyber attack. A worm is an attachment (for example, an email) or a file that a user downloads from the Internet. The infected file attacks systems and begins to send copies of itself throughout the WWW. Unfortunately, if your PC is attacked by a worm, it may stop functioning completely. Here, we cannot fail to mention how important it is to download files from trusted and reliable sources.
• Trojan. This danger looks like an ordinary harmless application that you want to install. For example, you need a codec to watch video materials. After downloading a file with a Trojan, it is embedded in the system and can delete specific files. Another threat is the ability to completely format disks.
• Rootkits. These cyber attack types are “cunning bugs” that penetrate into the very core of your OS, where they can intercept its main functions. The peculiarity of this threat is that rootkits always cover up the traces of their introduction into the system.
• Spy software. The goal of such software is not just to get into your PC; they need to collect as much important data as possible for cybercriminals. Often, this is the data that you are trying to hide. Imagine the consequences if such software penetrated the state computer network or the PCs of scientific research institutes.
• Scareware. This cyber attack vector pops up on your screen and says that it has detected an error in the system or a virus. Then, it offers you a super solution, and you see a download button (to protect yourself 100% from all cyber threats). The goal of such an attack is to force the victim to follow a link, download a dangerous file, and install it. Once in the system, the program begins to operate, and you experience a data leak, theft of banking information, system failures, and so on.
• Keyloggers. This type of attack is very well designed to steal as much personal information as possible from users’ devices. It monitors people online and tracks their activity. Then, more aggressive actions are used to begin: hacker’s code breaks into the system and takes more confidential information from it.

If we take the 2017 cyber attack or earlier years, now the situation is much more complicated because cryptocurrencies have appeared. Virtual attackers are not sitting idle; they are also looking for ways to hack this niche. The concept of cryptojacking or hidden mining appeared. Miners are a certain type of programs that spend device resources to generate different cryptocurrencies. Sometimes, people install such software themselves, but there are also illegal installations. The application is set up without your consent and then harms the computer system through viruses or malware or just slows it down.

But everyone should always be careful; malware is introduced when you don't expect it. It could be an infected email that looks like a message from your boss.

How is a worm different from a Trojan in United Kingdom and Ireland?

Worms are a type of computer program that looks for mistakes in a system and crawls into it to reproduce without infecting other files (like viruses). A Trojan is software that is activated through a simple program that you decide to install. By pressing a button, the Trojan begins its work and often disrupts the system or even destroys it.

Difference between virus and worm in UK and Ireland

The difference between virus and a worm is simple: a worm can be called a subtype of a virus because it also penetrates the system and harms it. But unlike a virus, a worm works locally. It can jump from PC to PC but does not “run” from file to file within the system.
