Microsoft says it found malicious software in its systems

From the article:

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.

Microsoft also had its own products leveraged to attack victims, said people familiar with the matter. The U.S. National Security Agency issued a rare “cybersecurity advisory” Thursday detailing how certain Microsoft Azure cloud services may have been compromised by hackers and directing users to lock down their systems.

However, Microsoft is denying that part:

“Like other SolarWinds customers, we have been actively looking for indicators of this actor and can confirm that we detected malicious Solar Winds binaries in our environment, which we isolated and removed,” a Microsoft spokesperson said, adding that the company had found “no indications that our systems were used to attack others.”
