Extreme-right student activists burst into the office of Macron’s political movement in the southeastern city of Lyon on Friday evening, setting off smoke grenades and scattering false bank notes bearing Macron’s picture, police said.
France is the latest nation to see a major election overshadowed by allegations of manipulation through cyber hacking after U.S. intelligence agencies said in January that Russian President Vladimir Putin had ordered hacking of parties tied to Democratic presidential candidate Hillary Clinton to influence the election on behalf of Republican Donald Trump.
Vitali Kremez, director of research with New York-based cyber intelligence firm Flashpoint, told Reuters his review indicated that APT 28, a group tied to the GRU, the Russian military intelligence directorate, was behind the leak.
Macron’s campaign has previously complained about attempts to hack its emails, blaming Russian interests in part for the cyber attacks.
The Kremlin has denied it was behind any such attacks, although Macron’s camp renewed complaints against Russian media and a hackers’ group operating in Ukraine.
