(CNN) - An alarming new alert issued by the Department of Homeland Security's cyber arm Thursday revealed that Russian hackers suspected of a massive, ongoing intrusion campaign into government agencies, private companies and critical infrastructure entities used a variety of unidentified tactics and not just a single compromised software program.
Specifically, the Cybersecurity and Infrastructure Security Agency said it has determined that the SolarWinds Orion software vulnerability disclosed earlier this week is not the only way hackers compromised a variety of online networks -- warning that in some cases, victims appeared to have been breached despite never using the problematic software.
The news will likely only compound already escalating concerns about the scale and scope of the data breach, which CISA said Thursday "poses a grave risk" to networks across both the public and private sector.'
