Another hacking group was involved in a cyberattack that targeted SolarWinds software, which was used by a number of federal government agencies, said Microsoft in an update.

An investigation revealed “an additional malware that also affects the SolarWinds Orion product but has been determined to be likely unrelated to this compromise,” said Microsoft on Dec. 18. The malware was most likely “used by a different threat actor,” it said, suggesting another group may have been involved in the breach.
