Russian threat actors associated with the Killnet organization have taken credit for an extensive cyberattack against Lithuania on Monday. Lithuanian defense officials stated that a distributed denial-of-service (DDoS) attack occurred against a secured data network, the State Tax Inspectorate, the Migration Department, and several other entities. This attack is in a retaliation from Killnet in response to Lithuania suspending all transportation of steel, coal, and other metal materials through the country due to European Union sanctions against Russia. After the first wave of DDoS attacks, Killnet proceeded to target networks of Lithuanian airports, specifically of Vilnus Airport, Kaunas Airport, and Palanga Airport, reportedly effectively rendering taking down their systems inaccessible for a brief period. Following the Lithuanian airport attacks, threat actors targeted telecommunications companies, including the Central State Archive, and Supreme Administrative Court. Killnet threat actors gloated about the attacks on their Telegram channel, stating the explicit targeting of an online accounting system used by Lithuania and Lativa, as well as the future targeting of additional network infrastructure in Lithuania. With tensions continuing to grow from the Russia/Ukraine conflict, CTIX analysts expect these attack trends to continue for the months to come.
