The National Coordination Center of Cyber Security of the National Security and Defense Council of Ukraine (NSDC) warns about new mechanisms of attacks on the Ukrainian infrastructure launched recently by the Russian hackers, as NSDC reported.
“Since February 18, 2021, the National Coordination Center of Cyber Security is spotting massive DDoS attacks on the Ukrainian segment of the internet, mostly on the websites of the security and defense sector. Particularly, the websites of the Security Service of Ukraine, the NSDC, resources of other state bodies and strategic enterprises were attacked,” the message said.
It is established that the source of these coordinated cyber attacks is IP addresses owned by particular Russian networks of traffic exchange. The perpetrators used a new mechanism of cyber-attacks during which the vulnerable web servers of the state bodies were infected with viruses that made them the elements of the bot networks used for DDoS attacks on other resources.
The security systems of the internet providers determined the discredited web servers as the sources of the attacks and started to block their work through automatic blacklisting. Thus, after the end of the cyber attacks, the websites remain unavailable for users.
As we reported, the number of phishing attacks using the topic of coronavirus vaccination has increased in Ukraine. The hackers created a fake website that mimicked the website of the Ukrainian Ministry of Health.
