More Cyber Attacks Disable Ukrainian Websites
Wednesday’s denial-of-service attacks on government, financial sites resemble earlier ones attributed to Russia.
Various financial and government websites in Ukraine were temporarily disabled on Wednesday by heavy denial-of-service attacks that resembled ones last week attributed to Russia by U.S. officials.
Around 4 p.m. local time, attackers began to direct large volumes of fake traffic to various websites. The public-facing sites of the Cabinet of Ministers, Security Service of Ukraine, the Verkhovna Rada legislature, and the Ministry of Foreign Affairs were briefly knocked offline, according to Ukraine’s Center for Strategic Communications. The public website of Privatbank, a financial company, was also rendered temporarily inaccessible.
“Now they are already working, but there are possible interruptions,” the center said.
The attacks resembled ones that struck Ukrainian sites last week. On Feb. 18, Anne Neuberger, Deputy National Security Advisor for Cyber and Emerging Technology, attributed those attacks to Russian military elements "transmitting high volumes of communication to Ukraine-based IP addresses and domains.”
On Wednesday, a senior U.S. defense official on Wednesday said, "There's more sites that were attacked than were a couple of weeks ago. It's certainly a piece of their playbook, but we haven't been able to ascribe attribution, specifically at this time.”
