“Massive cyberattack” against Ukrainian ISP has been neutralized, says Ukraine





Ukrainian internet service provider Ukrtelecom was the target of a “massive cyber attack,” the Ukrainian government said Monday. By 12:35 a.m. PT on Monday, the attack had been neutralized, according to the State Service for Special Communications and Information Protection (SSSCIP) of Ukraine.

The attack on core IT infrastructure affected the entire country, according to global internet access tracker NetBlocks, which led to the worst internet outage on record in Ukraine since the Russian invasion. NetBlocks said that, according to network data, connectivity appeared to collapse to 13% of pre-war levels.

The SSSCIP said Monday afternoon that Ukrtelecom was resuming services. However, the agency said on Twitter: “In order to maintain its network infrastructure and continue to provide services to the Ukrainian Armed Forces and other military formations, as well as to the customers, #Ukrtelecom has temporarily limited its services to the majority of private users and business customers.”

In a separate statement Monday, SSSCIP chairman Yurii Shchyhol said “the first cyber war in human history is underway.”

The “entire IT community of the world” is united against the Russian invasion, Shchyhol added, calling on companies like Microsoft and Oracle to help Ukraine. In addition, the SSSCIP said it can “assume” on the basis of reports that the “hacker community opposing Russia” aims to destroy the military infrastructure that threatens Ukraine.

“Our main challenge today is victory over the enemy on all battlefields, including cyberspace,” the SSSCIP said in a release. “Each of us can help in this fight by following the rules of cyber hygiene: do not open unknown messages, do not download files whose origin is not clear, treat all incoming information critically.”
