Ukraine on Monday accused Russian internet networks of massive attacks on Ukrainian security and defence sites, but did not provide details about any damage or say who believed it was behind the attack. Kyiv has accused Moscow of orchestrating major cyber attacks as part of a “hybrid war” against Ukraine, contradicting Russia’s denial.
However, a declaration by the National Security and Defence Council of Ukraine did not show who it believed that had organised the attacks or give any details of the effect that the intrusions had on Ukrainian cybersecurity.
The attacks began on 18 February and were aimed at websites of the Ukrainian Security Service, the Council itself and some other state institutions and strategic companies, it said in a statement. “It was shown that the addresses of certain Russian transport networks were the source of these coordinated attacks,” the Council said. The Council added that the attacks attempted to infect the government’s vulnerable web servers with a virus that added them to a bot-net used for DDoS attacks against other resources.
A DDoS attack is a cyber attack where hackers try to flood a network with unusually high traffic volumes to paralyze it.
Ukraine’s and Russia’s relations have been very problematic since the Russian annexation of Crimea in Ukraine in 2014 and participation in a conflict in the eastern Donbass region of Ukraine, which, according to Kiev, has killed 14000 people.
This month, the Ukrainian army said that five of their staff were killed last week in the east of the country, despite a ceasefire with pro-Russian separatists. On Monday, the military informed another dead soldier who had been killed by a rocket propelled grenade.
