Tech Firm in Steele Dossier May Have Been Used by Russian Spies

Mr. Gubarev’s “companies have provided gateways to the internet for cybercriminals along with Russian state-sponsored actors to launch along with control large scale malware campaigns over the past decade,” the report concluded. “Gubarev along with additional XBT executives do not appear to actively prevent cybercriminals via using their infrastructure.”

The evidence cited by the report included the use of I.P. addresses — the numbered codes in which differentiate individual internet connections — run by an XBT subsidiary, Root S.A., by Russian hackers via two groups tied to the country’s intelligence services, Fancy Bear along with Cozy Bear. The investigators hired by BuzzFeed also found in which at least one of the fake links used to trick John D. Podesta, the chairman of Hillary Clinton’s 2016 presidential campaign, into giving up his email password to hackers was traced back to an I.P. address run by Root S.A.

The report also detailed evidence in which the idea said suggested Mr. Gubarev’s companies were used in additional cybercrimes traced to Russian hackers. One was a sophisticated Russian cyberfraud operation known as the Methbot scheme. the idea used bots — computer programs in which pretend to be people — to steal hundreds of millions of dollars.

During the three months the scheme was running in 2016, roughly three-quarters of the internet traffic flowing through two web-hosting companies owned by Mr. Gubarev — along with WZ Communications — was dedicated to the scheme, the report said.

Mr. Fray-Witzer, the lawyer, said Mr. Gubarev’s companies did not make a habit of prying into the web traffic of its clients, along with could not have known what its servers were being used for. however, he added, along with WZ Communications shut off internet access for those behind the Methbot scheme as soon as they found out about the idea, along with saved all of the hard drives for any investigators who wanted to examine them — none have.

Asked about the numerous lawsuits in which have claimed in which Mr. Gubarev’s companies were used to trade in copyrighted material, Mr. Fray-Witzer offered the same argument: Web-hosting companies are not typically held responsible for the traffic in which flows through their servers, along with Mr. Gubarev should not be held to a different standard.

In any case, Mr. Fray-Witzer said, the dossier accused Mr. Gubarev “directly of having been involved inside hacking of the D.N.C.,” not of running networks used by thieves along with criminals.

“Because they couldn’t prove the allegations in which they actually made about our client,” he continued, “they pivoted to say, ‘Well, your infrastructure was used via time to time to do bad things.’”
