VILNIUS The Baltic state of Lithuania, on the frontline of growing tensions between the West and Russia, says the Kremlin is responsible for cyber attacks that have hit government computers over the last two years.
The head of cyber security told Reuters three cases of Russian spyware on its government computers had been discovered since 2015, and there had been 20 attempts to infect them this year.
"The spyware we found was operating for at least half a year before it was detected – similar to how it was in the USA," Rimtautas Cerniauskas, head of the Lithuanian Cyber Security Centre said.
When presented with the allegations, President Vladimir Putin's spokesman Dmitry Peskov told Reuters they were "laughable" and unsubstantiated.
"Did it (the spyware) have 'Made in Russia' written on it?" quipped Peskov. "We absolutely refute this nonsense." He said Russia itself was targeted in cyber attacks "round the clock," but said it would be stupid to accuse foreign governments.
Fears of Russian cyber attacks have come to the fore since the U.S. election campaign when hacking of Democratic Party emails led to allegations from U.S. intelligence that Moscow was involved.
Lithuania, Estonia and Latvia, all ruled by Moscow in communist times, have been alarmed by Russia's annexation of Ukraine's Crimea peninsula in 2014 and its support for pro-Russian separatists in eastern Ukraine.
In what Baltic officials say was a wake-up call, Estonia was hit by cyber attacks on extensive private and government Internet sites in 2007. State websites were brought to a crawl and an online banking site was closed.
Lithuanian intelligence services, in their annual report, say cyber attacks have moved from being mainly targeted at financial crimes to more political spying on state institutions.
Russian spyware was transferring all documents it could find, as well as all passwords entered on websites such as GMail or Facebook, to an internet address commonly used by Russian spy agencies, Cerniaukas said.
"This only confirms that attempts are made to infiltrate our political sphere," said Cerniaukas.
Germany's domestic intelligence agency reported earlier this month a striking increase in Russian targeted cyber attacks against political parties and propaganda and disinformation campaigns aimed at destabilizing German society.
The domestic intelligence chief said Russia may seek to interfere in its national elections next year.
Although no Russian cyber meddling was detected in the run up or during the Lithuanian general election in October, Cerniauskas said his country needs to understand it is vulnerable to such meddling.
"Russians are really quite good in this area. They have been using information warfare since the old times. Cyberspace is part of that, only more frowned upon by law than simple propaganda", he said.
"They have capacity, they have the attitude, they are interested, and they will get to it – so we need to prepare for it and we need to apply countermeasures."
Lithuanian officials targeted by the Russian spyware held mid-to-low ranking positions at the government, but their computers contained a stream of drafts for government decisions of its positions on various matters, said Cerniauskas.
The head of the Lithuanian counter-intelligence agency Darius Jauniskis said Russia tried to sow chaos in Lithuania by orchestrating a cyber attack in 2012 against the Lithuanian central bank and its top online news website.
"It is all part of psychological warfare," he told Reuters earlier this month.
