Documents unsealed Thursday in a lawsuit have shed new light on how hackers breached Democratic Party email accounts before the 2016 election.
The documents include a forensic analysis by a former top official in the FBI’s cybercrime division, which concluded that a Web server company owned by a Russian Internet entrepreneur was used by Russian operatives to hack Democratic Party leaders.
The Russian businessman, Aleksej Gubarev, has denied involvement in the hack, and his lawyers argued for months that the forensic analysis should be kept under seal and hidden from public view.
The analysis was completed as part of a federal lawsuit Gubarev filed in Florida against BuzzFeed, the online news outlet. Gubarev argued BuzzFeed defamed him by publishing a dossier written by former British spy Christopher Steele. The dossier alleged that hackers used servers from two of Gubarev’s companies — Webzilla and its parent company XBT Holding.
