The good news for the tech giant is that no damage was seemingly done according to the Seattle-based company.

"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 wrote Thursday in an update on the hack. "The account did not have permissions to modify any code or engineering systems and our investigation further confirmed no changes were made."
