Internet services in Lithuania came under “intense” distributed denial of service attacks on Monday as the pro-Russia threat-actor group Killnet took credit. Killnet said its attacks were in retaliation regarding Lithuania’s recent banning of shipments sanctioned by the European Union to the Russian exclave of Kaliningrad.

Lithuania’s government said that the flood of malicious traffic disrupted parts of the Secure National Data Transfer Network, which it says is “one of the critical components of Lithuania’s strategy on ensuring national security in cyberspace” and “is built to be operational during crises or war to ensure the continuity of activity of critical institutions.” The country’s Core Center of State Telecommunications was identifying the sites most affected in real time and providing them with DDoS mitigations while also working with international web service providers.

“It is highly probable that such or even more intense attacks will continue into the coming days, especially against the communications, energy, and financial sectors,” Jonas Skardinskas, acting director of Lithuania’s National Cyber Security Center, said in a statement. The statement warned of website defacements, ransomware, and other destructive attacks in the coming days.
