PARIS — Maybe it was the suspect timing of the leaked documents. Or the staggering amount and possibility that some were fake. Or a feeling among the French that, having witnessed how hacking may have altered the American election, they would not fall for the same ploy.

Whatever the reasons, newspapers and broadcasters in France have so far conspicuously avoided reporting any details of what was described on Friday night as a “massive” pre-election hacking attack on Emmanuel Macron’s campaign.

The bereft coverage extended into Monday night, well after a 44-hour legal ban on election reporting surrounding the Sunday vote had lifted.

By then it was clear that the hacked material — regardless of what it might contain — had caused no ill effects on the campaign of Mr. Macron, who won decisively over the far-right candidate Marine Le Pen.
