Ukraine’s national telecommunications service provider has been hit by a important cyber-attack, major to the “most severe” disruption to internet connectivity in the region considering the fact that the start off of the conflict with Russia.
Ukrtelecom, the country’s most significant company of fastened internet in terms of geographic protection, verified the incident yesterday and said it is progressively restoring connectivity soon after productively mitigating the attack.
The telecommunications supplier discussed it temporarily restricted entry to non-public buyers and corporations to be certain internet solutions to critical infrastructure and armed forces ended up not interrupted. In a statement, Ukrtelecom’s main government Yuriy Kurmaz wrote: “In buy to guard the critical network infrastructure and not interrupt services to the Armed Forces, other navy bodies and consumers of critical infrastructure, we have been forced to temporarily limit internet obtain to most personal end users and small business prospects.”
The State Support of Unique Communication and Information Security of Ukraine (SSSCIP), the nation’s specialized security and intelligence company, blamed the attack on “the enemy,” Russia. Yuriy Shchygol, head of the SSSCIP, said several towns had been dropped connectivity very last evening, like Berdyansk and Melitopol.
International internet monitor Netblocks reported that the attack was the “most severe” disruption to internet company in Ukraine considering that the Russian invasion started in late February, with connectivity dropping to 13% of pre-war levels.

Commenting on the tale, Toby Lewis, head of risk assessment at Darktrace, reported: “It is no surprise that a main internet company has been specific. Interrupting telecommunication infrastructure is an predicted exercise for a armed forces invasion and carries increased significance in a war becoming dubbed ‘World War Wired.’
“At this stage, we have minimal details, but the readily available network action appears to demonstrate a gradual decrease in connectivity, relatively than a cliff-edge fall regular of DDoS or a ransomware attack at the main of the network. This would propose a provide chain attack wherever endpoint devices this kind of as household routers are gradually currently being taken out. We noticed a similar attack on ViaSat that took spot on the day of the invasion alone, and beforehand with the Solarwinds Orion marketing campaign, wherever the serious harm only transpired soon after updates or malicious configuration improvements ended up pushed out to shoppers.
“Some of the outages we’re viewing may possibly be a result of the incident response actions taken by Ukrtelecom. The service provider is rightly prioritizing critical infrastructure above household and professional prospects, which is most likely to have significant-handed implications.”
There are fears this incident may possibly sign an escalation in cyber-functions adhering to the Russian invasion of Ukraine. So far, the cyber-dimension of the conflict has been somewhat minimal-critical, revolving all-around strategies like DDoS attacks and website defacements rather than trying to choose down critical infrastructure services. On the other hand, major wiper malware campaigns were found to be targeting govt, IT and non-profit corporations throughout Ukraine in the days before the invasion began.
