Jan 30 (Reuters) - Russia's domestic spy agency was likely responsible for cyberattacks late last month on 30 Polish renewable energy facilities, a manufacturing firm and a plant supplying heat for nearly 500,000 customers, Polish officials said on Friday.
A report by Poland's Computer Emergency Response Team on the incident - which a Polish minister said was the worst of its kind in years - pointed to a team of hackers from Russia's Federal Security Service, known by its Russian acronym FSB.
