Ukrainian Computer Emergency Response Team (CERT-UA) said that Ukraine was hit by large-scale DDoS attacks.
CERT-UA has published a report on ongoing DDoS attacks on Ukrainian websites and a government web portal.
The code is executed on the visitor’s computer and generates a huge number of requests in order to stop the websites from working. Cyberattacks occur without the knowledge of the owners of compromised sites and create subtle performance disruptions for users.
By the way, we talked about the State Department Offers $1 million for Info on Russian Hackers.
In addition, it is important to keep the content management systems (Content Management Systems, CMS) of the site up to date, update plugins and restrict access to site management.
We also note that it seems that the Chinese comrades do not support Russian hackers: we wrote that Chinese Mustang Panda Cyberspies Attack Russian Officials.
