We are used to using new technologies daily. We know its benefits, but sometimes we forget the risks we take when browsing the web. One of them is cyber-attacks.
This computer attack can cause our computers to become infected. Allowing access to the computer system will affect information such as our bank details, credit cards, email, social networks and millions of dollars in the event of cyber attacks on companies.
wpkraken shows you what types of cyber attacks exist and what to do if we suffer from one. I’m sure you’re interested; keep reading!
What is a cyber attack?
Before going into depth, we must explain the technical concepts. What is a cyber attack?
In this context of cyber wars, we must say that it is a set of offensive manoeuvres which aims to destabilize, take control or damage a computer system, be it the private network or computer, or destroy databases or companies.
The attacker or attackers can be an organization or an individual. These claim to have control of the computer system. This is for any malicious damage, such as stealing information or doing harm. They can be directed at systems and equipment that operate on the network and cancel their services, such as information or data storage. They can use it to spy or steal.
This is done using malicious codes that corrupt any algorithms, private data, and principles. The consequences are that this generates compromise and significantly violates information security.
More and more criminal organizations dedicate their activity to using malicious software. This is because its profitability is high, and its infrastructure is less complex. It is also more challenging to be discovered since following their trail is complex.
How many types of cyber attacks are there?
In the criminal world, digital or analogue, there are different ways of acting. On the Internet, the same applies completely. There are other ways depending on how it is done, the purpose of it, and even its victim. Here are the most common:
- Virus: this concept may sound familiar to you. These are found in the files and programs that, when executed by the user, spread and infect the device.
- Worm: it is also another of the best known. Its main characteristic is that it does not require the user to intervene for it to spread with viruses; instead, they “creep” from one terminal to another within the same network.
- Trojan: another well-known concept. They need to be executed. It differs from the previous ones in that they do not camouflage or spread but instead open a back door that allows them access.
- Phishing: consists of deceiving the user through their email or a false web page where personal information, bank details, passwords, etc., are requested.
- Spyware: These do not spread. They are executed automatically every time an infected computer is turned on. They collect information that will be sent to a third party without authorization.
- Denial of service or Denial of Service: these, as their name suggests, block or saturate a system. Its goal is to exhaust resources, and it does this by launching many connection requests at once. To do this, several devices prepared for this action are usually used. They cause an inability for requests to be completed.
- Ransomware: This is very well known, but few know its name. It blocks access to a computer through software, and a monetary payment is requested for it to be released. The ransomware attack is applied to large companies with millions of customers for greater profitability.
These are some of them, although there are others such as a rootkit, adware, malware, and SQL injection, among others.
