Since Lithuania, Poland and Estonia have also received similarly threatening messages, the Latvian State Police (VP) has offered to create a joint cooperation group with these countries to work on a joint, coordinated investigation of the case, Latkovskis revealed.
"Seeing that Western democratic countries are being attacked, I can say with 99% certainty that it is most likely Russia that is organizing it," Latkovskis said.
Meanwhile, scientist, cyber security and artificial intelligence technology researcher at the Rīga-based NATO STRATCOMCOE center Gundars Bergmanis-Korāts explained in the program that in order to catch the culprit, it is necessary to assess what type of cyber infrastructure was used to send out the threatening e-mails.
"Very often, people can be caught based on their mistakes, which are revealed in various open sources," said Bergmanis-Korāts, adding that there are technological possibilities to hide using various networks, and hidden IP addresses.
