Discrediting Lithuania and NATO
The recent hacking incident is aimed at discrediting Lithuania and NATO, the Baltic country's National Defence Minister Juozas Olekas says.
Security flaws will be identified during an investigation and measures will be taken to remove vulnerabilities, he said.
"I see it as a possible hacking incident, and we are carrying out an investigation to identify what measures are necessary to avoid such incidents in the future. The contents was provocative and aimed at discrediting Lithuania and NATO," Olekas told journalists on Thursday. "It is undoubtedly an initiative of people or institutions unfriendly for Lithuania and NATO."
The minister acknowledged that "both sides are improving" – hackers and institutions in charge of cyber security, and it will be "a good lesson" for future considerations of additional security measures.
