In the last years, we have seen how different attackers targeted crypto exchanges, users and investors. Just in 2017, cyber attacks caused $275 million dollars in damages to businesses according to Equifax.

It is possible for hackers to steal private information, sensible data, virtual currencies or other funds. In order to remain competitive, hackers and cyber attackers have invented new ideas to steal funds.

In this article we will be describing some of the most common attacks.

Ransomware is a new way of stealing private information that requires the attacker to introduce a file in the victim’s system. Once the file is installed, the hacker will be using advanced phishing methods that will give him the information about important files.

If the victim opens the file that the hacker sent, the hacker would be able to lock and encrypt a specific folder, file or document. The user would not be able to access to them. Indeed, the hacker would be sending a message to the victim saying that he would have to pay a certain amount of Bitcoin or other virtual currency.

In 2017, these attacks grew exponentially. Some of the favorite targets are important companies or government agencies.

Internet of things – also known as IoT – is one of the latest technologies that are being implemented and developed in the world. It allows objects from our daily lives such as TVs, cars, washing machines and other devices, to be connected to the internet and interact with each other.

The main intention of this technology is to make our lives easier.

However, if a group of IoT devices are connected to the internet, then, they are clearly more vulnerable to attacks and cyber threats.

Hackers can have access to these devices and create important damage to the company or victim. It is possible to know certain patterns such as at which time the owners of a flat arrive at night or which day the victim leaves the home.

This is one of the oldest methods for hackers to attack today. Attackers identify themselves as a company or a services provider that request information about the victims. Everything seems very legitimate, and it is very easy to provide the information that they request.

If a hacker contacts all the employees of a company saying that he is the administrator and that he needs private information, some employees would certainly give the information. In this way, it is possible to give the password or username of an account or even private information such as ID number or a picture of the passport.

Although this kind of attack is quite old and used in many different industries, there will always be victims. Attackers will become very cautious and strict with the information they ask and in this way they would be able to access the information they want.

In the last year, as virtual currencies grew at an exponential rate, some hackers decided to start working in Twitter. Attackers create fake profile accounts of important figures in the space such as Vitalik Buterin or Changpeng Zhao. Then, they start commenting under popular tweets saying that they give away virtual currencies for free. But there is only one condition to participate, the victim should send ETH or BTC before.

This is a more difficult and complicated strategy used by hackers. They use a powerful software that enters millions of passwords with the intention to find the correct one.

In general, people use simple passwords to enter their platforms and services. This is why, it is always important to have secure (complex) passwords.

If there is a person using an unsecure network, there may be a hacker trying to spy on other people’s devices. A company is at risk at all times when workers do not use a secure network. If a hacker has access to the victim’s computer, then, it can access sensitive information such as passwords, usernames or emails.

It may not be easy to avoid cyber attacks. There are many different ways to execute them, and hackers are learning new techniques all the time. Individuals should always use secure networks, avoid opening emails from untrusted sources or use complex passwords.
