The federal Cybersecurity and Infrastructure Security Agency (CISA) said Thursday that the hacking campaign that targeted the federal government is larger than what was previously known.

The alleged foreign actors gained backdoor access in more ways than through the SolarWinds software, which was publicly disclosed by the FBI and Department of Homeland Security (DHS) earlier this week.
