The Internet is transforming the world we live in. Considered as impossible yesterday is child's play today. But also there detractors in the online space.
Here you will see the most popular categories of digital threats - Malware, Virus, Worm, Fishing and Farming, Hacking and how with little steps we can be protected from these.
Malware is a collective term for malicious software, as viruses and worms are being the most popular. Generally speaking, their goal is to access sensitive information or steal your computer's resources. It is very possible as a user, you do not suspect that you have malware installed, but at the same time it is stealing sensitive information or sending spam emails from your account. Malware has many faces, but is most often hidden in another file or masked as a harmless application or program. Sometimes this "bad" software is synchronizing in order to overthrow a larger target. A botnet is a group of connected malware-infected devices. Compromised machines are called zombies, and as we know well from the movie world, a zombie army can destroy even the best protected fortresses.
Digital viruses are malicious code, often hidden behind the mask of something seemingly safe or even useful. Like a parasite, the virus attaches to your system through a file or program and starts to reproduce when a specific event occurs (for example, working with an infected program, the onset of a selected hour, etc.). In addition to copying, viruses usually have a specific purpose - from displaying a message to completely destroying the information you store. The most common viruses are the Trojan horse - a program that misleads the user about its function, leaving a backdoor for cybercriminals and so on. logic bomb - software that destroys or alters information in the presence of a predefined precondition.
The computer worm has a similar function of the virus - to reproduce without control, causing damage - with the only difference that it does not need to be attached to a program or file. The worm exists independently as a separate piece of software and does not need special conditions to be distributed locally to your computer or network. The worm can be added to you as email, infected site, chat applications, etc.
What can you do?
•Update your operating system as well as the antimalware package as often as possible.
•Periodically scan your operating system.
•Think beforeyou click - attachments from unfamiliar email addresses or suspicious links are among the things to watch out for.
•Don't trust pop-ups - standalone messages (usually ads) that pop up on your screen without being invited or requested.
•Make copies periodically of important files separately - in the cloud or on external memory.
•Always keep your firewall on - this is another built-in protection that can prevent trouble
Fishing & Farming
These terms are part of the so-called Social Engineering category. This basically describes a set of manipulation methods for retrieving sensitive information. The most popular frauds in this category are fishing and farming. Phishing is a practice that gets you an email that looks real and secure, but at the same time prompts you to fill in valuable information under false pretext. The sender may be hiding behind the mask of your bank, trustworthy company, or a generous Nigerian prince who needs your banking details to send you several million dollars. Like phishing, pharming is a practice that redirects you to a fake webpage where you enter your data so that it is forwarded to the fraudster. The more authentic the page looks, the harder we can understand that they are trying to deceive us.
What can you do?
•Be careful before downloading a file or clicking on a link (avoid suspicious shortcuts, such as misspellings or numeric links only).
•Keep your valuable information as your eyes - a large company would never ask you to send identifying or confidential information, and no one would ask you to share your password.
•When entering sensitive data into a web page, check that https is presented in front of domain name - this is a protocol that guarantees a secure connection and an authentic source.
•If it sounds too good to be true, then it is not. Always think twice before sharing your information.
•Always check the source, especially for suspicious emails. The mask of a seemingly legitimate sender falls easily at the sight of an apparently fake email address.
The threats we have mentioned so far are, to some extent, automatic - the hacker lets his bad luck go by and watches the world burn. But sometimes a dark hooded subject decides to deal with you personally. An example of this is the Man-in-the-middle attack, where the enemy is conveniently located between you and your final destination. As a mediator, he has full access to communication. To hide its traces, a hacker can use Rootkit, a set of programs that hide the presence of unwanted processes while giving administrative rights to the attacker. As a last resort, a hacker may try to guess your password based on a sample error or so-called brute force attack.
What can you do?
•We will repeat because you have to - always, always, always update your operating system and anti-malware package.
•Any unsolicited messages or pop-ups are a good enough sign of fraud.
•Firewall literally means "fire wall". So always keep it on so you don't get burned.
•Be creative with your passwords - any characters, letters, numbers are welcome, and we recommend updating them fairly often.
How do you know that your device is infected?
•Let's start with the obvious - when your security software detects a threat, then you've pulled the short straw
•Strange messages pop up on your screen - pop-ups
•You have no space on the computer without doing anything special
•Random file appearance
•Your machine is unbearably slow
•Your cursor is moving on its own
•Your computer shuts down at its discretion
•Your browser homepage has been changed
