By Michael Novinson January 27, 2021, 09:23 AM EST Fidelis Cybersecurity was a target of interest to the SolarWinds hackers after installing a trial copy of malicious SolarWinds Orion network monitoring software in May. The company said it identified a four-day period in May where a machine on its network communicated with the malware’s infrastructure in the initial passive phase of the attack, said Chief Information Security Officer Chris Kubic. The malware then flagged the Fidelis machine for the second associated phase of the attack, indicating that the company was a target of interest to the SolarWinds hackers.
