But this hasn't "turned out to be false". It's unconfirmed and thus very suspicious. This is an article about an attack so advanced it's generally considered impossible, using the most valuable attack vector in the most important battlefield (see DNI Maguire's hearing answer to the biggest threat facing America) between the world's two superpowers. Would it really be that shocking if, after an initial leak, the US government was able to shut down leaks? You make good points, particularly around the public denials, and I don't want to debate this any further (I was mostly railing against that ridiculous quote), but I think people are being pretty quick to claim this report is false rather than probably false. 130,000 people worked on the atomic bomb for 6 years in secret - when it comes to matters the government considers crucial to national security (and cutting edge breakthroughs in cyber warfare would certainly qualify), silence can be kept.
