Ukraine Delivers One of Largest Cyberattacks in History, Source Says

On the evening of Tuesday, July 30, hackers from Ukraine’s Main Intelligence Directorate (HUR) completed one of the largest Distributed Denial-of-Service (DDOS) attacks in history, derailing Russia’s internet infrastructure, hitting critical resources and gaining access to a vast array of confidential data, sources in Ukrainian intelligence told the Kyiv Post on Wednesday morning.

According to a Ukrainian intelligence source, the attack lasted continuously for a week. It affected the online services of all major Russian banks, including the Central Bank, telecommunications service providers, national payment systems, social networks and messengers, government resources, and dozens of other services.

All the attacked resources were in some way involved in supporting or financing the Russian Federation’s armed aggression against Ukraine.

“We can now exhale and confirm the completion of the operation. Thank you to everyone who participated, helped, and supported. Of course, this is just a prelude to even more interesting events,” the source said. “We advise the Russians to start digging a grave for their digital infrastructure.”

“It’s time for the enemy to recall the idea of an isolated, inherently Russian ‘CheburNet’ with moats, digital guards, and firewalls around the perimeter. See you in the next act of this captivating story.”
