America’s adversaries have more room to operate, at least in the disinformation space, cybersecurity experts say.

This month, a network of pro-Russian websites began a campaign aimed at undermining confidence in the U.S. defense industry, according to disinformation analysts.
The F-35 fighter jet was one target. The effort, coordinated by a Russian group known as Portal Kombat, spread rumors that American allies purchasing the warplanes would not have complete control over them, the analysts said.
In the past, U.S. cybersecurity agencies would counter such campaigns by calling them out to raise public awareness. The F.B.I. would warn social media companies of inauthentic accounts so they could be removed. And, at times, U.S. Cyber Command would try to take Russian troll farms that create disinformation offline, at least temporarily.
But President Trump has fired General Timothy D. Haugh, a four-star general with years of experience countering Russian online propaganda, from his posts leading U.S. Cyber Command and the National Security Agency.
