Lithuanian energy company hit by DDoS attack

Ignitis Group, a state-controlled energy holding firm in Lithuania has been hit by a hacker attack disrupting online services amid mounting geopolitical tensions caused by Russia's invasion of Ukraine.

According to Ignitis Group, no critical infrastructure networks were damaged by the distributed denial-of-service event.

Even as the cyberattack has subsided, the firm warned that threat actors continued to probe for an opening. Cloudflare is providing DDoS protection to the firm.

Lithuania has faced a spate of intensive DDoS attacks over the past few weeks from Russia-supporting hacktivist groups (see: Lithuanian Government Issues DDoS Attack Alerts). A top Ministry of National Defense official earlier this month tweeted that Russia has placed his country under intensive DDoS pressure:

Ignitis Group commented on the cyber security incident in a social media post:

We experience attacks all the time. For the last few weeks we experienced DDoS attacks, but it did not affect our websites.

On Saturday night around 3 am the intensity of the attack was increased and we experienced malfunctions in our websites. Around midday we resolved the problems and suppressed the attack.

The Baltic country is a main supply chain chokepoint for the Russian exclave of Kaliningrad. Last month, it banned the transit of materials sanctioned by the European Union, including coal, metals and advanced technologies, leading to angry accusations from Russia that Kaliningrad is under siege.

In the same time the other Baltic country Latvia has come under the most intense massive wave of hacker attacks in its history, including a 12-hour onslaught on its public broadcasting center.
