Security experts, however, point out that, despite this fact, DDoS attacks can still cause a major disruption to traffic, even if their developers are not primarily focused on financial gain.
"During the third quarter, the invaders were most active in August and September, as evidenced by the high numbers of attacks on educational institutions that have steadily increased since the beginning of the academic year. The most striking attacks in the period under review hit the website of one of the UK's most prestigious universities – the University of Edinburgh. He was also an American provider of web services for parents of children attending private schools in a number of American cities – Infinite Campus, "said Alexey Kiselev, a member of DDoS Protection Team at Kaspersky Lab.
DDoS attacks were recorded in 82 countries between July and September of this year. Most attacks took place in China, followed by the United States and Australia in the unflattering ranking. It was the first time in the DDoS attacks ranking high.
"The main driver of any cybercrime activity is profit. However, this may not only be of a financial nature. An example of this is DDoS attacks on universities, schools, and other educational institutions most likely to stand alone students who want to make work more difficult for their cantors or simply delay the test, "Kiselev said.
It is also important that these attacks are not carried out with the help of botnets that usually have professional cybercriminals. "It seems that you are now more focused on the illegal mining of cryptos and occasional profitable attacks. An initiative demonstrated by pupils and students could be reserved in certain circumstances if it did not cause real damage to the affected organizations. It is therefore clear that even educational institutions are more interested in cyber security and prepared for similar attacks, "concluded a security expert.
For similar attacks, unintentionally computer pirates also help some users who do not even worry about securing their devices. It should be noted that the speech is not only about smart phones and classical computers, but also for example the so-called Internet-based devices (IoT) – for example, the various cameras that can connect to the Internet.
It is these devices that have become part of a giant botnet that has used cybercriminals to attack Dyn DNS servers. By default, they translate web addresses into physical addresses of physical machines (IP addresses). This is why hackers have been able to disable several large sites off the East Coast of the US – because the compiler (DNS servers) did not work, web browsers did not know where to connect.
Users could not connect to Twitter, Facebook, the Daily News, CNN and the New York Times, and the Spotify and Soundcloud music portals. [celá zpráva]
Emphasis on security
End-user attacks use computer piracy very often with various viruses to control the attacked station remotely. It then assigns it to a giant botnet, whereby if they are of sufficient size, they can virtually eliminate any destination on the Internet.
To prevent DDoS attacks, first of all, the users themselves, when they put enough emphasis on the security of their devices.
