Emmanuel Macron gestures after speaking at the Parc des Expositions in Paris, France, on April 23, 2017.

French presidential frontrunner Emmanuel Macron has qualified for next month's runoff election, but a Russian government-linked group seems eager to slow down the campaign's progress.

According to research from cybersecurity firm Trend Micro, members of the hacking team known as Fancy Bear — called Pawn Storm by the report's author — created phishing domains related to the Macron campaign, such as "onedrive-en-marche.fr," plausibly similar to En Marche!, Macron's political party. The domains were spotted by the researchers as they were created by the group, which likely used them in an attempt to steal credentials and hack the Macron campaign.
