"This incident involving spam emails has already been resolved," Rytis Rainys, head of NKSC, told BNS.

"(Spam) filters have been fixed, and the Seimas members won't receive such emails anymore," he said.

According to the center, the spam that reached the systems of the Seimas office was sent from a botnet with a large range of IP addresses.

The 15min.lt news website has reported that the parliamentarians hit by the attack included Foreign Minister Linas Linkevičius and MPs Arvydas Anušauskas, Gabrielius Landsbergis, Rasa Juknevičienė, Laurynas Kasčiūnas, Andrius Kubilius and Kęstutis Masiulis of the opposition conservative Homeland Union – Lithuanian Christian Democrats, as well as Liberal MP Aušrinė Armonaitė and Mantas Adomėnas of the non-attached group.

Liudvikas Jonikas of the parliament's IT division described it as a targeted attack on a certain group of people.

However, R. Rainys said he could neither confirm nor deny it was a targeted attack.
