One of the most significant cybersecurity events in recent history also seems to have ensnared Microsoft, which Reuters reported Thursday was also infiltrated by the Russian hacking groups that inserted malware into the software updates of a prominent IT company called SolarWinds.
Microsoft representatives had no immediate comment on the report, which did not specify the Microsoft products that were affected by the hack. If confirmed, this breach could be far more significant than the one that affected SolarWinds, which makes monitoring software for corporate networks. Microsoft software has been used inside countless businesses and government organizations around the world for decades.
Update 4:56pm: Microsoft said that it had "detected malicious SolarWinds binaries in our environment" but had found no evidence that its products were compromised or used to conduct further attacks on its customers.
