Ukrainian Sites Saw a 10x Increase Attacks Since Russia Invaded Ukraine

On Tuesday, Wordfence posted on their site that they found a massive number of systems owned by Ukrainian universities were compromised. This coincided with the attack of Russia on Ukraine.

Nearly 30 Ukraine-based universities were hacked by a member of the Monday hacker group. Nevertheless, the attacker exposed himself publicly as “theMx0nday” and gave out a statement that he stands by Russia on this issue.

The hacker was based out of Brazil and used “Njalla” an internet service provider that is claimed to be the most notorious Privacy as a service provider of domains, VPSs, and VPNs. Njalla is a Swedish-based hosting provider owned by Peter Sunde. Peter Sunde was also the co-founder of Pirate Bay which is the largest provider of pirated software.

Wordfence stated that they found servers used for routing were owned by Njalla in Finland. However, Njalla has denied this saying their servers were based out of Secret locations in Sweden. Wordfence came up with solid evidence of the facts that they stated as explained below.

IP’s that Performed the Attack

Wordfence saw a log of nearly 7000 IP addresses during the attack period. However, most of the IPs did not log more than 100 attacks. Except for four IP addresses that were causing almost all of the attacks. The IPs are as follows

IPNumber of attacks
185[.]193[.]127[.]179169,132
159[.]223[.]64[.]15626,074

217.77.209.2421991

185[.]193[.]127[.]179 and Peter Sunde

The IP that logged most of the attacks was owned by Njalla, the hosting provider that was owned by Peter Sunde who was also the co-founder of Pirate Bay. Wordfence allegedly states that Njalla was behind these attacks since they claim themselves as the “most notorious service provider on VPN and VPS” on their homepage.

Wordfence also said that there might be chances that the attacker might be one of their customers, or one of their servers were hacked. It was also described that they targeted educational institutions in Ukraine. The IP 185[.]193[.]127[.]179  A massive amount of 171,000 attacks were conducted on the university sites, few were on government agencies and three individual websites whose name was not revealed.

It seems like the attack was also targeted on companies in Ukraine and some of the attacks were targeted at Brazil.

Wordfence also published various attacks conducted by the “theMx0nday” hacker group. The report also included the duration of time of the attacks and their spike during the Russian Ukraine war.
