Microsoft says it found malicious software in its systems

Microsoft Corp said on Thursday it found malicious software in its systems related to a massive hacking campaign disclosed by U.S. officials this week, adding a top technology target to a growing list of attacked government agencies.

The Redmond, Washington company is a user of Orion, the widely deployed networking management software from SolarWinds Corp which was used in the suspected Russian attacks on vital U.S. agencies and others.
