Story highlights Macron's party: Document dump mixed fake and real documents to create confusion

French voters will head to the polls Sunday in race between Macron and Marine Le Pen

(CNN) French presidential candidate Emmanuel Macron has been the victim of a "massive and coordinated hacking operation," his campaign team said, slamming the attack as a last-ditch attempt to undermine him before Sunday's election.

The document dump happened Friday night, less than 48 hours before the country votes in the final round of the presidential election, which pits the independent centrist Macron against the far-right Marine Le Pen.

The files were released just before 2 p.m. ET Friday, around four hours before the election campaign period officially closed with its restrictions on campaigning, reporting and polling. These restrictions are aimed at preventing last-minute scandals from emerging and influencing the election's outcome.

Around 14.5 gigabytes of emails, personal and business documents were posted to the text-sharing site Pastebin through links to more than 70,000 files, a CNN look at the data shows.

Officials from Macron's En Marche! party said in a statement that the perpetrators of the hack had mixed fake documents with authentic ones "to create confusion and misinformation."
