Microsoft Corp. said the suspected Russian hackers behind the stunning breach of numerous U.S. government agencies also accessed the company’s internal source code, although no customer data or services were compromised.

“We detected unusual activity with a small number of internal accounts and upon review, we discovered one account had been used to view source code in a number of source code repositories,” Microsoft said Thursday in a blog postBloomberg Terminal that updated its continuing investigation of the attack. “The account did not have permissions to modify any code or engineering systems and our investigation further confirmed no changes were made.”
