Microsoft Corp. said its systems were exposed to the malware used in the Russia-linked hack that targeted U.S. states and government agencies, adding that investigations so far show the malicious software wasn’t used to attack others and didn’t impact customer data or outward-facing systems.

The company is a customer of SolarWinds Corp., whose software the hackers are believed to have used to gain access to networks by installing malicious code. Microsoft found code related to that cyber-attack “in our environment, which we isolated and removed,” spokesman Frank Shaw said in a statement posted to his Twitter account. “We have not found evidence of access to production services or customer data.”
