There are many types of hacker attacks. It is important to be aware of the most common types of attacks that hackers use to hack your computer.

  • Mailbombing. This is one of the oldest types of hacker attacks. A significant increase in traffic and the number of messages sent lead to the malfunction of server. It paralyzes not only your mail, but also the work of the mail server itself. This type of attack is used very seldom today.
  • Viruses, trojans, mailworms, sniffers. This type of attack combines various third-party programs. The purpose and principle of operation of such programs can be extremely diverse, so it makes no sense to dwell on each of them. All these programs are united by the fact that their main goal is to get access and “infect” the system.
  • Man-in-the-middle. Hacker intercepts a communication channel between two applications. As a result, he gets access to all the information going through this channel. The purpose of the attack is not only theft, but also falsification of information.
  • DoS (Denial of Service) — attack which aims to make server not respond to the requests. This type of attack does not directly imply obtaining some secret information, but is used to paralyze the work of target services.
  • DDoS (Distributed Denial of Service) – a subtype of DoS attacks, which has the same purpose as DoS. But it is conducted from multiple computers belonging to the same network. It leads to the failure of victim’s server. DDoS is used if conventional DoS is ineffective.

How to protect your device from hacking?

Now we know how and why attackers can hack computers. It’s time to share tips on how to prevent this from happening.

  1. Be careful when shopping online. It is better not to make purchases from other people’s devices as it can save your username and password, bank card information etc. Attackers can copy your data and use it for their own purposes. All you need to follow: use a secure network, use strong passwords, make sure that you visit safe online shops, never store card data in your online accounts, check your bank card transactions weekly.
  2. Do not use simple passwords. It is not difficult for a professional hacker to hack your computer if the password is 12345. Use complex encryption. For example, capital and small letters in a word, combine numbers with letters in order to create passwords for your accounts.
  3. Never leave your laptop or smartphone unlocked for a long time. Even if you just walked away for a few minutes and left your gadget accessible, a professional hacker will have enough time to enter the system.
  4. Use end-to-end data encryption. This type of data protection is very popular among companies, as it is considered one of the most reliable in the world. Most of the messengers use this type of protection, so access keys are stored exclusively on users’ devices. This means that without gaining access to the device, third parties will not be able to access the information.
  5. Regularly check the applications which are installed on your computer. Applications which you don’t use should be removed with the help of special utilities and programs such as MacKeeper. This will reduce the risk of hacking the system and increase the performance of the computer.
  6. Two-factor authentication. This implies not only a strong password, but also certain information or a fact that is known exclusively to the user. For example, it could be his voice, fingerprint, smart card, or something else.
