Russian government hackers lurked in the records system of the US courts for years and stole sensitive documents that judges had ordered sealed from public view, according to two people familiar with the matter and a report seen by Bloomberg News.
The attackers had access to what was supposed to be protected information for multiple years, the report on the breach shows. They gained access by exploiting stolen user credentials and a cybersecurity vulnerability in an outdated server used by the federal judiciary, according to the report, which says the hackers specifically searched for sealed records.
