Romanian government websites and financial institutions were hit by a series of DDoS (distributed denial of service) attacks carried out by a Russian hacker group known as Killnet.

According to Serviciul Român de Informații (SRI), the Romanian intelligence service, the attacks started on April 29 and affected websites belonging to the Romanian government entities, including defense ministry, border police, railway company CFR Calatori and a financial institution, which were not available for several hours.

SRI said in a statement that the attackers used compromised network equipment outside Romania to launch DDoS attacks. Earlier this month, the Killnet hacker group launched DDoS attacks on the websites of institutions in the US, Estonia, Poland, the Czech Republic, as well as NATO sites.

Last week, Ukraine’s CERT team warned of DDoS attacks targeting pro-Ukraine websites using hacked WordPress websites containing a malicious JavaScript code, tracked as BrownFlood, which generates malicious traffic to a list of URL addresses included in the malicious code.

Cybersecurity Help statement on the critical situation in Ukraine

On February 24, people in many cities and towns across Ukraine woke up to the sounds of explosions and artillery fire, as the Russian Federation launched a full-scale invasion of the country. Such actions are unacceptable, political ambitions of any man aren’t worth of blood, tears, and destruction of millions of lives. We give our full support to the Ukrainian people in these hard times. No more war! Слава Україні!
